在virtualenv中使用pip install时出现“权限被拒绝”错误

Question

Edit: FIXED!

Just had to chown the .cache directory

I've tried the virtualenvwrapper docs instructions, I've tried this guy's instructions as well as these ...I've tried sudo pip uninstall virtualenv , sudo pip uninstall virtualenvwrapper , sudo pip3 uninstall virtualenv , sudo pip3 uninstall virtualenvwrapper before attempting each set of instructions. I've looked at other SO posts like this one , but the sudo issue isn't the same as my own. By this, I mean that I don't use sudo when making the virtualenv, and if I try to use sudo to pip install a package, it'll just say that I've already installed the package (outside of the virtualenv).

I've also tried doing pip install --user virtualenv(wrapper)

Here's what I did:

~ $ sudo pip3 install virtualenv
Downloading/unpacking virtualenv
  Downloading virtualenv-13.0.3-py2.py3-none-any.whl (1.7MB): 1.7MB downloaded

~ $ mkdir ~/.virtualenvs
~ $ sudo pip3 install virtualenvwrapper

Cleaning up...
~ $ export WORKON_HOME=~/.virtualenvs/

Then I added these two lines to my .bashrc: (I also tried setting VIRTUALENVWRAPPER_PYTHON to /usr/bin/python )

source /usr/local/bin/virtualenvwrapper.sh
VIRTUALENVWRAPPER_PYTHON='/usr/bin/python3'

Next I tried this:

~ $ mkvirtualenv test
New python executable in test/bin/python
Installing setuptools, pip, wheel...done.
(test)~ $ pip install numpy
Collecting numpy

Why can't virtualenv just work?

Answer 1

I think that if you do that pip install numpy --no-cache-dir it will work.

If you run pip --help you will find:

--no-cache-dir Disable the cache.

Hope that it can help to someone in the future.

Answer 2

you need to change the owner of directory of pip.

run chown -R <user>:<group> /home/aweeeezy/.cache/pip .
