virtualenv错误错误的解释器：无此文件或目录

Question

如果尝试创建虚拟环境，则会收到此错误消息，我不理解该错误消息：解释错误：没有这样的文件或目录。我已经查看了此堆栈溢出答案，并尝试在以下诊断步骤中应用它。

这是我在Mojave上跑步的第一天，但​​我不知道这是否是造成此问题的因素。

我为位于以下位置的项目创建了一个新的空文件夹 /Users/Wes/Dropbox/Programming/Python/glade_againn

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，出现此错误消息。

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

如果我尝试通过PIP安装virtualenv，则会被告知已经存在。

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

我当前的路径是

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/

如果您在所有这些目录中搜索pyth *，则会按此顺序获得此列表。

是否有人对如何使virtualenv重新工作提出建议？

Answer 1

尝试使用此重新安装

pip install -U --force-reinstall virtualenv

如果以上解决方案对您不起作用，则由于莫哈韦沙漠更新，您应该再次创建一个新的virtualenv

Answer 2

就我而言，我正在重命名项目和项目venv所在的文件夹。

因此，就我而言，我在以下文件中更改了 python 解释器的路径：

~/PycharmProjects/myproject/venv/bin/activate*

并将~/PycharmProjects/myproject/venv/bin/pip*文件修改为：

#!/home/myuser/PycharmProjects/myproject/venv/bin/python
# -*- coding: utf-8 -*-
import re
import sys
from pip._internal.cli.main import main
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

要修改它，我需要使用root权限登录：sudo su。只是sudo vim.tiny venv/bin/pip不允许我编辑文件。

我只更改了第一行#!/home...

Answer 3

就我而言，我使用的是MacOS，并且安装了 python3.9，但 virtualenv 是使用 python3.7 安装的，并且在某个时候我卸载了 python3.7。

$ /usr/local/bin/virtualenv --version
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory

然而，我的Python版本：

$ which python3.9
/usr/local/bin/python3.9

无论有多少 pip 或 pip3 install/uninstall/install virtualenv 对我来说都不起作用。最后我做了以下事情：

$ python3.9 -m pip install --user virtualenv
Collecting virtualenv
  Using cached virtualenv-20.4.6-py2.py3-none-any.whl (7.2 MB)
<snip>
Successfully installed appdirs-1.4.4 distlib-0.3.1 filelock-3.0.12 virtualenv-20.4.6

进而

$ /usr/local/bin/virtualenv --version
virtualenv 20.4.6 from <mypath>

耶！！
