python - 在 virtualenv 中使用 pip 安装时出现“权限被拒绝”错误

Question

编辑:已修复!

只需要 chown .cache 目录

我试过 virtualenvwrapper docs说明，我试过了this guy's instructions以及these ...我试过 sudo pip uninstall virtualenv , sudo pip uninstall virtualenvwrapper, sudo pip3 uninstall virtualenv, sudo pip3 uninstall virtualenvwrapper 在尝试每组指令之前。我看过其他 SO 帖子，例如 this one ，但 sudo 问题与我自己的问题不同。通过这个，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 安装包，它只会说我已经安装了包(在 virtualenv 之外)。

我也试过 pip install --user virtualenv(wrapper)

这是我做的:

~ $ 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
Downloading/unpacking virtualenvwrapper
  Downloading virtualenvwrapper-4.5.1-py2.py3-none-any.whl
Requirement already satisfied (use --upgrade to upgrade): virtualenv-clone in /usr/local/lib/python3.4/dist-packages (from virtualenvwrapper)

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

然后我将这两行添加到我的 .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'

接下来我尝试了这个:

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

为什么 virtualenv 不能正常工作？

我认为，如果您这样做，pip install numpy --no-cache-dir 它将起作用。

如果你运行 pip --help 你会发现:

--no-cache-dir 禁用缓存。

希望对以后的人有所帮助。
