virtualenv 错误解释器错误：没有这样的文件或目录

Question

如果我尝试创建一个虚拟环境，我会收到此错误消息，我不明白它是： bad interpreter: No such file or directory 。我已经查看了 这个堆栈溢出答案，并尝试将其应用到下面的诊断步骤中。

这是我在 Mojave 上运行的第一天，但我不知道这是否是导致此问题的一个因素。

我在 /Users/Wes/Dropbox/Programming/Python/glade_againn 为项目创建了一个新的空文件夹

我的计划是在 virtualenv 中运行项目 /Users/Wes/.virtualenvs/glade_againn

但是，当我尝试使用 virtualenv 时，我收到此错误消息。

 $ virtualenv --version
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

如果我尝试使用 PIP 安装 virtualenv，我会被告知它已经存在。

 $ pip install virtualenv
Requirement already satisfied: virtualenv in /usr/local/lib/python2.7/site-packages (15.2.0)
$

我目前的路径是

echo $PATH
/Library/Frameworks/Python.framework/Versions/3.6/bin:/opt/local/bin:/opt/local/sbin:/usr/local/opt/postgresql@9.4/bin:/usr/local/Cellar/postgresql/9.5.4_1/bin/psql/:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Applications/Wireshark.app/Contents/MacOS:/usr/local/git/bin:/Users/Wes/bin:/sw/bin:/usr/local/bin:/Users/Wes/.sdkman/candidates/groovy/current/bin/

有没有人建议如何让 virtualenv 再次工作？

Answer 1

尝试使用此重新安装

pip install -U --force-reinstall virtualenv

如果上述解决方案对您不起作用，您应该因为 mojave 更新而再次创建一个新的 virtualenv
