Pip 在 Python3 中安装索引器错误 Windows 10

Question

My cloned app from git repository need module indexer in the app. So I install indexer using python3 :

python3 -m pip install indexer //this is equal to pip3 install indexer*

However it generates this error:

I search it and I got an answer from this stackoverflow question .

So it seems it is a problem with a different syntax from a different python version.

I tried to install it with python2 and it works. But since I use python3 to run it, I search another indexer module that compatible in python3 and I found python3-lzo-indexer and tried to install it. But when I run it with python3 , it still missing module indexer .

How can I install indexer with python3 ?

Someone already asked on stackoverflow here but still there is no solution

*) I used the command above since I install a dual version of python ( python2 and python3 ) on my machine. Even though that is not the case.

Answer 1

Reinstall Python and try again. I tried to reproduce this error.

Running python3 -m pip install indexer gives this error.

The Downloading line shows where it's being downloaded from so you can just download the tar.gz from there and unpack it. In the base folder you should see a setup.py file. THe Traceback from the previous error gives you a good hint on where the error occurred. This line

except OSError, ex:

is invalid python 3 syntax and translates to

except OSError as ex:

in python 3.

So you need to change lines 107 and 116 to that as they'll both have the same syntax error. Additionally, there's an import which needs to be changed. Change line 14 from

from os.path import isdir, exists, join, walk

to this

from os.path import isdir, exists, join

and add another line beneath it like this

from os import walk

In python 3 walk is called from directly inside the os module.

When that is saved you can just run python3 -m pip install <path to base folder> where <path to base folder> is the folder that setup.py is in.

DISCLAIMER:

This will only get you part of the way as this package is intended for python 2.

After installing it, I can see in Lib\site-packages\indexer\postgres8_indexer.py , Lib\site-packages\indexer\search.py , and probably other places there are a few instances of the python 2 print statement. These can obviously be changed as you come across them but there are most likely other more subtle syntax differences.
