python - 无法使用 mkvirtualenv， "site-packages/_markerlib"权限被拒绝

Question

编辑，这似乎是一般权限问题:

The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was:
/Library/Python/2.7/site-packages/
Perhaps your account does not have write access to this directory?

我发现了这个问题，这正是我的问题，但我没有 ~/.pydistutils.cfg 文件:

virtualenv: could not create '/lib/python2.7': Permission denied

我也确实安装了 setuptools 和命令行工具，如下所述:Error when ex mkvirtualenv in Mountain Lion

我用 sudo 安装了所有东西，但我不能在这里使用 sudo:

sudo: mkvirtualenv: command not found

回溯:

mkvirtualenv myenv
......stuff here......

build/lib/setuptools/_backport/hashlib
running install_lib

error: could not create '/Library/Python/2.7/site-packages/_markerlib': Permission denied

Answer 1

sudo chown -R your-username:wheel /Library/Python/2.7/site-packages

您可能需要 chmod 目录的权限和/或卸载并重新安装 virtualenv:

sudo pip uninstall virtualenv
sudo pip uninstall virtualenvwrapper
sudo pip install virtualenv 
sudo pip install virtualenvwrapper
echo "source `which virtualenvwrapper.sh`" >> ~/.bash_profile 
. ~/.bash_profile
