Why do I get the following error when doing this in python:
>>> import locale
>>> print str( locale.getlocale() )
(None, None)
>>> locale.setlocale(locale.LC_ALL, 'de_DE')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/locale.py", line 531, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting
This works with other locales like fr or nl as well. I'm using Ubuntu 11.04.
Update: Doing the following did not yield anything:
dpkg-reconfigure locales
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8",
LANG = (unset)
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
Run following commands
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales
It will solve this.
Make sure to match the .UTF-8
part to the actual syntax found in the output of locale -a
eg .utf8
on some systems.
According to this link , it solved by entering this command:
export LC_ALL=C
You probably do not have any de_DE
locale available.
You can view a list of available locales with the locale -a
command. For example, on my machine:
$ locale -a
C
C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
it_CH.utf8
it_IT.utf8
POSIX
Note that if you want to set the locale to it_IT
you must also specify the .utf8
:
>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'it_IT') # error!
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/locale.py", line 539, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting
>>> locale.setlocale(locale.LC_ALL, 'it_IT.utf8')
'it_IT.utf8'
To install a new locale use:
sudo apt-get install language-pack-id
where id
is the language code (taken from here )
After you have installed the locale you should follow Julien Palard advice and reconfigure the locales with:
sudo dpkg-reconfigure locales
One of the above answer provides the solution:
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales
However, if you are providing your code to work on the client machine then this is a bad approach. I also tried executing the above commands using os.system(), but still it doesn't work.
locale.setlocale(locale.LC_ALL,'en_US.UTF-8')
More permanent solution would be to fill the missing values, in the output shown by command: locale
Output from locale
is:
$ locale
LANG=en_US.utf8
LANGUAGE=
LC_CTYPE="en_US.utf8"
LC_NUMERIC=es_ES.utf8
LC_TIME=es_ES.utf8
LC_COLLATE="en_US.utf8"
LC_MONETARY=es_ES.utf8
LC_MESSAGES="en_US.utf8"
LC_PAPER=es_ES.utf8
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT=es_ES.utf8
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=
To Fill the missing values edit ~/.bashrc :
$ vim ~/.bashrc
Add the following lines after the above command (suppose you want en_US.UTF-8 to be your language):
export LANGUAGE="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
If this file is ReadOnly you would be needing to follow the steps mentioned by The GeekyBoy . The answer given by Dr Beco in Superuser has details relating to saving readonly files.
After saving the file do:
$ source ~/.bashrc
Now you wont be facing the same problem anymore.
如果您使用的是 Debian(或 Debian fork),您可以使用以下命令添加语言环境:
dpkg-reconfigure locales
You error clearly says, you are trying to use locale something was not there.
>>> locale.setlocale(locale.LC_ALL, 'de_DE')
Traceback (most recent call last):

locale.Error: unsupported locale setting
To check available setting, use locale -a
deb@deb-Latitude-E7470:/ambot$ locale -a
C
C.UTF-8
en_AG
en_AG.utf8

en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
POSIX
so you can use one among,
>>> locale.setlocale(locale.LC_ALL, 'en_AG.utf8')
'en_AG.utf8'
>>>
for de_DE
This file can either be adjusted manually or updated using the tool, update-locale.
update-locale LANG=de_DE.UTF-8
在 Arch Linux 上,我可以通过运行sudo locale-gen
来解决这个问题
For the record, I had this same problem, but none of the solutions worked. I had upgraded my computer and migrated my PC. I had aa mixed locale english and spanish:
$ locale
LANG=en_US.utf8
LANGUAGE=
LC_CTYPE="en_US.utf8"
LC_NUMERIC=es_ES.utf8
LC_TIME=es_ES.utf8
LC_COLLATE="en_US.utf8"
LC_MONETARY=es_ES.utf8
LC_MESSAGES="en_US.utf8"
LC_PAPER=es_ES.utf8
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT=es_ES.utf8
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=
But, on my new Debian installation, I just selected english as locale. Which finally worked was to reconfigure locales package to add and generate spanish too.
$ grep -v "#" /etc/locale.gen
en_US.UTF-8 UTF-8
es_ES.UTF-8 UTF-8
Place it in the Dockerfile
above the ENV
.
# make the "en_US.UTF-8" locale so postgres will be utf-8 enabled by default
RUN apt-get update && apt-get install -y locales && rm -rf /var/lib/apt/lists/* \
&& localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
ENV LANG en_US.UTF-8
Just open the .bashrc file and add this
export LC_ALL=C
and then type source .bashrc in terminal.
locale
to get what locale is used. Such as:LANG=en_US.UTF-8
LANGUAGE=en_US:en
LC_CTYPE=zh_CN.UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
/etc/locale-gen
file. Uncomment to used oneslocale-gen
to generate newly added localesIn my opinion, the easiest way to setup the local locale in python{,3} is:
>>> import locale
>>> locale.setlocale(locale.LC_ALL, '')
'de_DE.UTF-8'
Then, locale aware stuff just works, if you're on a decent linux distro, and should work on binary distributions of the other OSes as well (or that's a bug IMHO).
>>> import datetime as dt
>>> print(dt.date.today().strftime("%A %d. %B %Y"))

This error can occur, if you have just added a new locale. You need to restart the python interactive shell ( quit(
) and python
) to get access to it.
If I were you, I would use BABEL: http://babel.pocoo.org/en/latest/index.html
I got the same issue here using Docker, I've tried every single step and didn't work well, always getting locale error, so I decided to use BABEL, and everything worked well.
For those deploying a docker image and using a locale that isn't shown in the locale -a
command, add this line to your Dockerfile
RUN apt-get install -y locales
This should add all locales to your image, I used de_DE which is not part of AWS default Ubuntu server.
In trying to get python to spit out names in specific locale I landed here with same problem.
In pursuing the answer, things got a little mystical I find.
I found that python code.
import locale
print locale.getdefaultlocale()
>> ('en_DK', 'UTF-8')
And indeed locale.setlocale(locale.LC_TIME, 'en_DK.UTF-8')
works
Using tips here I tested further to see what is available using python code
import locale
loc_list = [(a,b) for a,b in locale.locale_alias.items() ]
loc_size = len(loc_list)
print loc_size,'entries'
for loc in loc_list:
try:
locale.setlocale(locale.LC_TIME, loc[1])
print 'SUCCES set {:12} ({})'.format(loc[1],loc[0])
except:
pass
which yields
858 entries
SUCCES set en_US.UTF-8 (univ)
SUCCES set C (c.ascii)
SUCCES set C (c.en)
SUCCES set C (posix-utf2)
SUCCES set C (c)
SUCCES set C (c_c)
SUCCES set C (c_c.c)
SUCCES set en_IE.UTF-8 (en_ie.utf8@euro)
SUCCES set en_US.UTF-8 (universal.utf8@ucs4)
SUCCES set C (posix)
SUCCES set C (english_united-states.437)
SUCCES set en_US.UTF-8 (universal)
Of which only above is working! But the en_DK.UTF-8
is not in this list, though it works!?!? What?? And the python generated locale list do contain a lot of combos of da and DK, which I am looking for, but again no UTF-8 for da/DK...
I am on a Point Linux distro (Debian based), and here locale
says amongst other LC_TIME="en_DK.UTF-8"
, which I know works, but not the locale I need.
locale -a
says
C
C.UTF-8
en_DK.utf8
en_US.utf8
POSIX
So definitely need to install other locale , which i did by editing /etc/locale.gen
, uncomment needed line da_DK.UTF-8 UTF-8
and run command locale-gen
Now locale.setlocale(locale.LC_TIME, 'da_DK.UTF-8')
works too, and I can get my localized day and month names.
My Conclision:
Python : locale.locale_alias is not at all helpfull in finding available locales!!!
Linux : It is quite easy to get locale list and install new locale. A lot of help available.
Windows : I have been investigating a little, but nothing conclusive. There are though posts leading to answers, but I have not felt the urge to pursue it.
if I understand correctly, the main source of error here is the exact syntax of the locale-name. Especially as it seems to differ between distributions. I've seen mentioned here in different answers/comments:
de_DE.utf8
de_DE.UTF-8
Even though this is obviously the same for a human being, the same does not hold for your standard deterministic algorithm.
So you will probably do something along the lines of:
DESIRED_LOCALE=de
DESIRED_LOCALE_COUNTRY=DE
DESIRED_CODEPAGE_RE=\.[Uu][Tt][Ff].?8
if [ $(locale -a | grep -cE "${DESIRED_LOCALE}_${DESIRED_LOCALE_COUNTRY}${DESIRED_CODEPAGE_RE}") -eq 1 ]
then
export LC_ALL=$(locale -a | grep -m1 -E "${DESIRED_LOCALE}_${DESIRED_LOCALE_COUNTRY}${DESIRED_CODEPAGE_RE}")
export LANG=$LC_ALL
else
echo "Not exactly one desired locale definition found: $(locale -a | grep -E "${DESIRED_LOCALE}_${DESIRED_LOCALE_COUNTRY}${DESIRED_CODEPAGE_RE}")" >&2
fi
python 查找 .UFT-8,但您可能有 .utf8 尝试使用 sudo dpkg-reconfigure locales 安装 .UFT-8 包
first, make sure you have the language pack installed by doing :
sudo apt-get install language-pack-en-base
sudo dpkg-reconfigure locales
Not the answer for this question but this question helped me to find the answer for my problem.
I had this problem when using inside a Docker container.
I solved by installing locales , adding my language to the locale.gen file, executing locale-gen (it reads from locale.gen) and finally setting LANG to my language.
For example, my Dockerfile:
RUN apt-get install -y locales
RUN echo "pt_BR.UTF-8 UTF-8" >> /etc/locale.gen
RUN locale-gen pt_BR.UTF-8
ENV LANG=pt_BR.UTF-8
