删除python2.7后，mkvirtualenv不工作

在我从笔记本电脑上删除python2.7之后，我开始出现这个错误。 我正在尝试使用

/bin/easy\u install

使用

mkvirtualenv

创建虚拟环境
我已经试过这个命令了

╭─ fsadykov ~
╰─() mkvirtualenv --python=`which python` example

这个呢

╭─ fsadykov ~

Python版本

╭─ fsadykov ~
╰─() python --version
Python 3.7.4

我想从我的MacBookPro中删除python2.7，如果它可以用于所有python3.7。但由于某种原因，我得到了这个错误

注意：此文件不存在

/bin/easy\u install

Could not install packages due to an EnvironmentError: [Errno 1] Operation not permitted: '/bin/easy_install'

嗨，我只能给你提个建议。您应该重新安装Python，然后再试一次—似乎缺少一些文件。然后将python和pip更新为最新版本。

我对VirtualEnvrapper不熟悉，但从日志记录来看，python 2.x似乎仍在使用。另外，您是否注意到日志记录中的警告：

请确保从/Users/fsadykov/.pydistutils.cfg文件中删除任何以前的自定义路径。

我不确定此文件的用途，但它可能包含Python 2.x安装的路径？？权限错误可能是因为您需要root访问权限（

sudo

）才能写入

/bin

。谢谢您的评论。我试过使用
