我正在尝试遵循Mozilla Django指南：
https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/development_environment
按照指南中的步骤，我已经成功安装了Python3.7.3和pip3。当我输入python3 -V和pip3 list时，将得到预期的响应。
下一步是安装 virtualenvwrapper 。我使用推荐的命令来做到这一点：
sudo pip3 install virtualenvwrapper
但是当我按下Enter键时，我收到以下警告：
The directory '/Users/myusername/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.

下一步是编辑文件 virtualenvwrapper.sh 。我可以在目录Macintosh HD/Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh中找到它。
但是，当我尝试编辑文件 virtualenvwrapper.sh 时，我收到Xcode的警告，指出 virtualenvwrapper.sh当前已锁定，因为您不是该文件的所有者，并且没有拥有写权限。
进行一些谷歌搜索，看来我有两种选择：
sudo -H命令进行安装，并永久使用-H。如果是这样，我是否需要卸载我第一次安装的virtualenvwrapper + python3 + pip3？推荐的解决方案是什么？ 预先感谢您的帮助。
