如何在MacOS High Sierra中使用pip安装virtualenv？

Question

我以前安装virtualenv的命令： -

sudo pip install virtualenv

结果： -

The directory '/Users/apple/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

The directory '/Users/apple/Library/Caches/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Requirement already satisfied: virtualenv in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

Answer 1

sudo -H pip install virtualenv

Answer 2

如果您在尝试运行pip时试图摆脱此错误，只需添加-H标志：

sudo -H pip install foo
