无法在虚拟环境中本地安装 PyMySQL [Errno 13] 权限被拒绝

Question

我正在尝试安全安装 PyMySQL。我读过很多关于为什么应该避免 sudo pip install 的很好的论点，但有时似乎无法摆脱。

有没有办法在 OSX 中本地安装 PyMySQL 而无需使用 sudo？

(VirtualEnv) : ^.^ :pip install --no-cache-dir --user PyMySQL

要在虚拟环境中安装运行此命令。

pip install --install-option="--prefix=/Users/TomNason/VirtualEnv/lib/python2.7" PyMySQL

通常 - 如果您无法在虚拟环境中使用 pip 安装 PyMySQL（即使您使用 --user 选项），您可以尝试...

pip install --install-option="--prefix=PATH_TO_YOUR_VIRTUAL_ENV_DIR/lib/PYTHON_VERSION" PyMySQL

这对我来说仍然是一个奇怪的情况。欢迎任何关于为什么我必须明确说明我的 python 目录的评论。我认为使用虚拟环境的原因是 pip 将始终选择安装在那里。
