编辑:修正!
只需修改.cache目录
我试过virtualenvwrapper docs指令,也试过this guy's instructions和these…我试过sudo pip uninstall virtualenv
在尝试每一组指令之前,sudo pip uninstall virtualenvwrapper
,sudo pip3 uninstall virtualenv
,sudo pip3 uninstall virtualenvwrapper
。我看过其他类似this one这样的帖子,但是sudo的问题和我自己的不一样。我的意思是,我在制作virtualenv时不使用sudo,如果我尝试使用sudo来pip安装一个包,它只会说我已经安装了这个包(在virtualenv之外)。
我也试过做pip install --user virtualenv(wrapper)
以下是我所做的:
~ $ sudo pip3 install virtualenv
Downloading/unpacking virtualenv
Downloading virtualenv-13.0.3-py2.py3-none-any.whl (1.7MB): 1.7MB downloaded

Cleaning up...
~ $ export WORKON_HOME=~/.virtualenvs/
然后我将这两行代码添加到.bashrc中:(我还尝试将VIRTUALENVWRAPPER_PYTHON
设置为/usr/bin/python
)
source /usr/local/bin/virtualenvwrapper.sh
VIRTUALENVWRAPPER_PYTHON='/usr/bin/python3'
接下来我试了一下:
~ $ mkvirtualenv test
New python executable in test/bin/python
Installing setuptools, pip, wheel...done.
(test)~ $ pip install numpy

为什么virtualenv不能工作?
我认为如果你那样做,它会起作用的。
如果运行
pip --help
,您将发现:--no-cache-dir Disable the cache.
希望对将来的人有帮助。
您需要更改pip目录的所有者。
运行
chown -R <user>:<group> /home/aweeeezy/.cache/pip
