Question

There is a thread解决了降级Python后如何使Jupyter正确链接的问题，但这是指Conda安装。我降级Python的动机是因为TensorFlow is broken on Python 3.7。

在卸载Jupyter并降级Python之后，我收到此错误。

/usr/local/bin/jupyter: /usr/local/Cellar/jupyter/1.0.0_5/libexec/bin/jupyter: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory
/usr/local/bin/jupyter: line 2: /usr/local/Cellar/jupyter/1.0.0_5/libexec/bin/jupyter: Undefined error: 0

如何正确链接Jupyter和Python才能正常工作？

谢谢，那库尔

Answer 1

首先尝试卸载jupyter笔记本：

brew uninstall jupyter（如果在Mac上）

或python3 -m pip uninstall jupyter

然后通过以下方式强制重新安装jupyter：

python3 -m pip install jupyter --force

Answer 2

首先，转到存储jupyter的cd /usr/local/bin/。

您可以通过输入nano jupyter notebook

#!/usr/local/opt/python/bin/python3.7
# -*- coding: utf-8 -*-
import re
import sys

from jupyter_core.command import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

然后，您需要从#!/usr/local/opt/python/bin/python3.7更改为#!/usr/local/opt/python/bin/python3.6

这就是我修复它的方式。

macOS：

如果您从酿造中获得Jupyter，则可以：

brew link --overwrite jupyter

这将使用指向/usr/local/bin/jupyter的符号链接覆盖您的../Cellar/jupyter/1.0.0_5/bin/jupyter

在我的安装中，该文件现在看起来像

#!/bin/bash
JUPYTER_PATH="/usr/local/etc/jupyter" PYTHONPATH="/usr/local/Cellar/jupyter/1.0.0_5/libexec/lib/python3.7/site-packages:/usr/local/Cellar/jupyter/1.0.0_5/libexec/vendor/lib/python3.7/site-packages" exec "/usr/local/Cellar/jupyter/1.0.0_5/libexec/bin/jupyter" "$@"

而不是早期的

#!/usr/local/Cellar/python/3.6.4_2/bin/python3.6

# -*- coding: utf-8 -*-
import re
import sys

from jupyter_core.command import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

这为您解决了确切的问题。

我敢肯定它可能会与conda环境发生冲突，因此我不希望它不会破坏其他内容。
