ImportError：没有名为 pip 的模块

Question

OS: Mac OS X 10.7.5 Python Ver: 2.7.5

I have installed setuptools 1.0 with ez_setup.py from https://pypi.python.org/pypi/setuptools Then I download pip.1.4.1 pkg from https://pypi.python.org/pypi/pip/1.4.1 .

Run (sudo) python setup.py install in iTerm shows that

Anyone who met the same problem before and can give me some tips to solve it?

Answer 1

I had the same problem. My solution:

For Python 3

sudo apt-get install python3-pip

For Python 2

sudo apt-get install python-pip

Answer 2

On Mac using brew is a better option as apt-get is not available. Command:

brew install python

In case you have both python2 & python3 installed on machine

python2.7 -m ensurepip --default-pip

simply should solve the issue.

If instead you are missing pip from python 3 then simply change python2.7 to python3 in the command above.

Answer 3

With macOS 10.15 and Homebrew 2.1.6 I was getting this error with Python 3.7. I just needed to run:

python3 -m ensurepip

Now python3 -m pip works for me.

Answer 4

After installing ez_setup , you should have easy_install available. To install pip just do:

easy_install pip

Answer 5

Try to install pip through Python:

Please go to: https://pip.pypa.io/en/stable/installing/

and download get-pip.py , and then run:

(sudo) python get-pip.py

Answer 6

On some kind of Linux, like distros based on Debian, you might want to consider updating your ' apt-get ' first, in case you are installing python-pip through it.

sudo apt-get update

This might help apt-get to update its indexes and locate the python-pip package. After this, u might install pip like this-

sudo apt-get install python-pip (Python2)
sudo apt-get install python3-pip (Python3)

Answer 7

Run

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Then run the following command in the folder where you downloaded: get-pip.py

python get-pip.py

Answer 8

I ran into this same issue when I attempted to install the nova client.

spencers-macbook-pro:python-novaclient root# python  setup.py install    
running install
/usr/bin/python: No module named pip
error: /usr/bin/python -m pip.__init__ install   'pbr>=0.5.21,<1.0' 'iso8601>=0.1.4' 'PrettyTable>=0.6,<0.8' 'requests>=1.1' 'simplejson>=2.0.9' 'six' 'Babel>=0.9.6' returned 1

I use homebrew so I worked around the issue with sudo easy_install pip

spencers-macbook-pro:python-novaclient root# brew search pip
aespipe     brew-pip    lesspipe    pipebench   pipemeter   spiped  pipeviewer

If you meant "pip" precisely:

Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
    sudo easy_install pip
spencers-macbook-pro:python-novaclient root# sudo easy_install pip

The commands should be similar if you use macports.

Answer 9

I think none of these answers above can fix your problem.

I was also confused by this problem once. You should manually install pip following the official guide pip installation (which currently involves running a single get-pip.py Python script )

after that, just sudo pip install Django . The error will be gone.

Answer 10

我从这里下载了pip二进制文件，它解决了这个问题。

Answer 11

I know this thread is old, but I just solved the problem for myself on OS X differently than described here.

Basically I reinstalled Python 2.7 through brew, and it comes with pip.

Install Xcode if not already:

xcode-select –install

Install Brew as described here :

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then install Python through Brew:

brew install python

And you're done. In my case I just needed to install pyserial.

pip install pyserial

Answer 12

I encountered the same error with Python 3.8.6 on MacOS Big Sur.

Whether I used pip or pip3 I'd get this error:

 File "/Users/marcelloromani/dev/<repository>/venv/bin/pip", line 5, in <module>
    from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip'

It turns out my virtualenv was out of date. This fixed the issue for me:

1. Remove the old virtualenv

$ deactivate
$ rm -rf venv

2. Initialise a new virtualenv

$ virtualenv venv
$ . venv/bin/activate

3. Install the new requirements then worked:

$ pip install -r src/requirements.txt

Answer 13

In terminal try this:

ls -lA /usr/local/bin | grep pip

in my case i get:

-rwxr-xr-x 1 root  root      284 Сен 13 16:20 pip
-rwxr-xr-x 1 root  root      204 Окт 27 16:37 pip2
-rwxr-xr-x 1 root  root      204 Окт 27 16:37 pip2.7
-rwxr-xr-x 1 root  root      292 Сен 13 16:20 pip-3.4

So pip2 || pip2.7 in my case works, and pip

Answer 14

Download:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

---

Then Install pip:

py get-pip.py

---

Then Install biopython:

py -m pip install biopython

---

I wish it would be useful

Answer 15

I encountered the issue ModuleNotFoundError: No module named 'pip' when I created a new Python 3 virtual environment using the command

python3 -m venv ~/venv/ontology    ## << note: "python3" (problematic)

which is a command often suggested (here, elsewhere). When I entered that venv, pip was nowhere to be found.

In the interim, since first using that command to create Python virtual environments, my system Python had upgraded (Arch Linux system updates) from Python 3.7.4 to Python 3.9.2.

The solution is to use the command

python -m venv <your_venv>  ## e.g. python -m ~/venv/ontology

When I did that ( python -m ... not python3 -m ... ), that venv now contained pip ...

To upgrade pip within that venv, use

<your_venv_path>/bin/python -m pip install --upgrade pip

## e.g.
## /home/victoria/venv/ontology/bin/python -m pip install --upgrade pip

Answer 16

If you get "No module named pip" in ubuntu, try this.

$python3 -m pip --version
/usr/bin/python3: No module named pip

$sudo apt-get install python3-pip

It worked for me.

After successful installation validate using

$python3 -m pip --version

To upgrade to latest pip version

$python3 -m pip install --upgrade pip

Answer 17

I solved a similar error on Linux by setting PYTHONPATH to the site-packages location. This was after running python get-pip.py --prefix /home/chet/pip .

[chet@rhel1 ~]$ ~/pip/bin/pip -V
Traceback (most recent call last):
  File "/home/chet/pip/bin/pip", line 7, in <module>
    from pip import main
ImportError: No module named pip

[chet@rhel1 ~]$ export PYTHONPATH=/home/chet/pip/lib/python2.6/site-packages

[chet@rhel1 ~]$ ~/pip/bin/pip -V
pip 9.0.1 from /home/chet/pip/lib/python2.6/site-packages (python 2.6)

Answer 18

my py version is 3.7.3, and this cmd worked

python3.7 -m pip install requests

requests library - for retrieving data from web APIs.

This runs the pip module and asks it to find the requests library on PyPI.org (the Python Package Index) and install it in your local system so that it becomes available for you to import

Answer 19

Tested below for Linux: You can directly download pip from https://pypi.org/simple/pip/ untar and use directly with your latest python.

tar -xvf  pip-0.2.tar.gz
cd pip-0.2

Check for the contents.

anant$ ls
docs  pip.egg-info  pip-log.txt  pip.py  PKG-INFO  regen-docs  scripts  setup.cfg  setup.py  tests

Execute directly:

anant$ python pip.py --help
Usage: pip.py COMMAND [OPTIONS]

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -E DIR, --environment=DIR
                        virtualenv environment to run pip in (either give the
                        interpreter or the environment base directory)
  -v, --verbose         Give more output
  -q, --quiet           Give less output
  --log=FILENAME        Log file where a complete (maximum verbosity) record
                        will be kept
  --proxy=PROXY         Specify a proxy in the form
                        user:passwd@proxy.server:port. Note that the
                        user:password@ is optional and required only if you
                        are behind an authenticated proxy.  If you provide
                        user@proxy.server:port then you will be prompted for a
                        password.
  --timeout=SECONDS     Set the socket timeout (default 15 seconds)

Answer 20

Here's a minimal set of instructions for upgrading to Python 3 using MacPorts:

sudo port install py37-pip
sudo port select --set pip pip37
sudo port select --set pip3 pip37
sudo pip install numpy, scipy, matplotlib

I ran some old code and it works again after this upgrade.

Answer 21

Followed the advise on this URL, to rename the python39._pth file. That solved the issue

https://michlstechblog.info/blog/python-install-python-with-pip-on-windows-by-the-embeddable-zip-file/#more-5606

ren python39._pth python39._pth.save

Answer 22

我只需要用pip3替换pip所以我最终运行了如下命令： pip3 install matplotlib

Answer 23

I had a similar problem with virtualenv that had python3.8 while installing dependencies from requirements.txt file. I managed to get it to work by activating the virtualenv and then running the command python -m pip install -r requirements.txt and it worked.

Answer 24

Try to re-install the pip use curl command to download the get-pip.py file:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

if curl is not working then open this link : get-pip.py

create a get-pip.py file in your directory copy the code from this link and put it in the get-pip.py file and save the file in the same directory. then run the command

python get-pip.py

Answer 25

I am using Debian, but this solution can also be applied for Ubuntu.

1. Usually, pip comes with python by default, in order to check if pip is installed in your system run.

 python -m pip --version

2. If pip is not there, install it using Aptitude Linux Package Manager,

 # For Python 2 sudo apt install python-pip # For Python 3 sudo apt install python3-venv python3-pip

3. I wouldn't use the get-pip.py script in Debian/Ubuntu, because in the documentation page mentions the following.

Be cautious if you are using a Python install that is managed by your operating system or another package manager. get-pip.py does not coordinate with those tools, and may leave your system in an inconsistent state.
