我最近删除了我的 Mac 并重新安装了 OSX El Capitan public beta 3。我使用 sudo easy_install pip 安装了 pip，并使用 sudo pip install virtualenv 安装了 virtualenv，但没有任何问题。

现在，当我尝试 sudo pip install virtualenvwrapper 时，我得到以下信息:

Users-Air:~ User$ sudo pip install virtualenvwrapper

由于问题似乎与 six 包有关，因此手动尝试使用 sudo pip uninstall Six 卸载它会导致相同的错误。输出也建议使用 -H 标志，但我仍然得到几乎相同的错误:

我使用 sudo nvram boot-args="rootless=0" 禁用了 rootless，但这没有任何效果。任何帮助将不胜感激!

最佳答案

您可以手动安装库存 10.11 安装中不存在的依赖项，然后使用 --no-deps 安装其他软件包以忽略依赖项。这样它会跳过 six (以及已经安装的 argparse )。这适用于我的 10.11 beta 6 安装:

sudo pip install pbr
sudo pip install --no-deps stevedore
sudo pip install --no-deps virtualenvwrapper

并且无需禁用无根。
