Question

如果我尝试创建虚拟环境，则会收到此错误消息，我不理解该错误消息：错误的解释器：没有此类文件或目录。我已经审查了this stack overflow answer，并尝试将其应用于以下诊断步骤。

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原因。

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 /Users/Wes/.virtualenvs/glade_againn

中运行项目

但是，当我尝试使用virtualenv时，会出现此错误消息。

$ 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PATH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。

有人对如何使virtualenv重新工作提出建议吗？

Answer 1

就我而言，我正在重命名项目和项目的文件夹，其中 venv 所在的位置。

所以就我而言，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，我需要以 root 权限登录：sudo su。 sudo vim.tiny venv/bin/pip 只是不允许我编辑文件。

我只更改了以 #!/home... 开头的第一行

Answer 2

尝试使用此方法重新安装

pip install -U --force-reinstall virtualenv

如果上述解决方案对您不起作用您应该由于莫哈韦沙漠更新再次创建一个新的virtualenv

Answer 3

就我而言，我使用的是 MacOS 并且安装了 python3.9，但是 virtualenv 是使用 python3.7 安装的，并且在某些时候我卸载了 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

但是，我的python版本：

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

没有多少 pip 或 pip3 install/uninstall/install virtualenv 对我有用。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

然后

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

耶！！

Answer 4

这解决了我的问题：（我的 env 文件名为 .venv)

mv .venv .venv_old
python3.7 -m venv .venv
source .venv/bin/activate
pip install wheel
pip install --upgrade pip wheel setuptools
pip install -r requirements.txt

virtualenv错误错误的解释器：没有这样的文件或目录
