linux - virtualenv安装linux错误

Question

尝试安装 virtualenv 时收到一个有趣的错误:

$ pip install virtualenv

产生以下错误:

Collecting virtualenv
  Using cached virtualenv-15.0.2-py2.py3-none-any.whl
Installing collected packages: virtualenv
Exception:

    shutil.copyfile(srcfile, destfile)
  File "/usr/lib/python2.7/shutil.py", line 83, in copyfile
    with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/virtualenv.py'

我想知道是否有人对解决这个问题有一些见解？我读到 usr/bin 中可能引用了旧版本的软件，这是可能的，但是这台计算机位于较新的一侧。最好的选择是进入并清除所有对“virtualenv”的引用(我能找到的就是)？

谢谢!

问题在于您尝试将软件包安装到通常需要 root 权限的位置。您可以按照 @Vince West 建议并运行 sudo pip install virtualenv ，或者你可以这样做pip install --user virtualenv ，这会将软件包安装到 ~/.local/lib/python<version>/site-packages 。如果您走这条路，您可能需要确保$HOME/.local/bin包含在您的$PATH中.
