How do I fix 'ImportError: cannot import name

问题:

When I try to install anything with pip or pip3, I get:

$ sudo pip3 install python3-tk
Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    load_entry_point('pip==1.5.6', 'console_scripts', 'pip3')()

  File "/usr/lib/python3/dist-packages/pip/download.py", line 25, in <module>
    from requests.compat import IncompleteRead
ImportError: cannot import name 'IncompleteRead'

I have a Ubuntu 14.10 system.

How can I fix this problem?

回答1:

While this previous answer might be the reason, this snipped worked for me as a solution (in Ubuntu 14.04):

First remove the package from the package manager:

# apt-get remove python-pip

And then install the latest version by side:

# easy_install pip

(thanks to @Aufziehvogel, @JunchaoGu)

回答2:

This problem is caused by a mismatch between your pip installation and your requests installation.

As of requests version 2.4.0 requests.compat.IncompleteRead has been removed. Older versions of pip, e.g. from July 2014, still relied on IncompleteRead. In the current version of pip, the import of IncompleteRead has been removed.

So the one to blame is either:

• requests, for removing public API too quickly
• Ubuntu for updating pip too slowly

You can solve this issue, by either updating pip via Ubuntu (if there is a newer version) or by installing pip aside from Ubuntu.

回答3:

For fixing pip3 (worked on Ubuntu 14.10):

easy_install3 -U pip

回答4:

Or you can remove all requests.

For example:

• rm -rf /usr/local/lib/python2.7/dist-packages/requests*

回答5:

On Ubuntu 14.04 I resolved this by using the pip installation bootstrap script, as described in the documentation

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

That's an OK solution for a development environment.

回答6:

The problem is the Python module requests. It can be fixed by

$ sudo apt-get purge python-requests
[now requests and pip gets deinstalled]
$ sudo apt-get install python-requests python-pip

If you have this problem with Python 3, you have to write python3 instead of python.

回答7:

This should work for you. Follow these simple steps.

First, let's remove the pip which is already installed so it won't cause any error.

Open Terminal.

Type: sudo apt-get remove python-pip

It removes pip that is already installed.

Method-1

Step: 1 sudo easy_install -U pip

It will install pip latest version.

And will return its address: Installed /usr/local/lib/python2.7/dist-packages/pip-6.1.1-py2.7.egg

or

Method-2

Step: 1 go to this link.

Step: 2 Right click >> Save as.. with name get-pip.py .

Step: 3 use: cd to go to the same directory as your get-pip.py file

Step: 4 use: sudo python get-pip.py

It will install pip latest version.

or

Method-3

Step: 1 use: sudo apt-get install python-pip

It will install pip latest version.

回答8:

Simply running easy_install -U pip resolved my problem.

回答9:

Check wether you have an older version of requests sitting in your ~/.local/lib/python2.7/site-packages/ and remove it if it is the case (change path to reflect your python version). This solved the issue for me.

回答10:

My version of pip on ubuntu suggests:

  pip install --upgrade pip

回答11:

In Windows, this worked from an administrative prompt:

• Delete C:\Python27\Lib\site-packages\requests*
• easy_install requests==2.3
• pip install --upgrade pip
• pip install --upgrade requests

回答12:

I tried with every answer below, but couldn't make it.

Did this and worked

sudo apt-get purge python-virtualenv
sudo pip install pip -U

After that I just installed virtualenv with pip

sudo pip install virtualenv

I builded the virtualenv that I was working on and the package was installed easily. Get into the virtualenv by using source /bin/activate and try to install your package, for example:

pip install terminado

It worked for me, although I was using python2.7 not python3

回答13:

Check if have a python interpreter alive in any of the terminal windows. If so kill it and try sudo pip which worked for me.

回答14:

1. sudo apt-get remove python-pip
2. sudo easy_install requests==2.3.0
3. sudo apt-get install python-pip

回答15:

You can download recent packages manually from these pages:

• https://packages.debian.org/fr/stretch/all/python3-pip/download
• https://packages.debian.org/fr/stretch/all/python-pip-whl/download

Then, install it by running dpkg:

dpkg -i *.deb

回答16:

For CentOS I used this and it worked please use the following commands:

sudo pip uninstall requests
sudo pip uninstall urllib3
sudo yum remove python-urllib3
sudo yum remove python-requests

(confirm that all those libraries have been removed)

sudo yum install python-urllib3
sudo yum install python-requests
