删除python2.7后mkvirtualenv不工作

Question

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_install创建具有virtualenvwrappermkvirtualenv的虚拟环境。
我试过这个命令

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

这个呢

╭─ fsadykov ~
╰─()  mkvirtualenv  example                                                                                                                                              1 ↵

版本

VirtualEnvrapper版本

╭─ fsadykov ~
╰─() mkvirtualenv --version

Python版本

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

我想从我的MacBookPro中删除python2.7，如果它是可行的并且可以用于python3.7的所有东西。但由于某种原因，我得到了这个错误。你知道吗

注意：此文件不存在/bin/easy_install
