安装python扩展时出错"无法打开文件“目录+文件名":[Errno 2] 没有这样的文件或目录“ [英] error while installing python extensions " can't open file 'directory + filename': [Errno 2] No such file or directory "

问题描述

我尝试在 vs 代码中安装 mypy 扩展，但它一直在下面显示这个错误

I tried to install mypy extension in vs code but it keeps showing me this error below

C:\Users\Yourusername\Dev\django_project_boilerplate\env\Scripts\python.exe: can't open file 'c:UsersYourusername.vscodeextensionsms-python.python-2020.6.89148pythonFilespyvsc-run-isolated.py': [Errno 2] No such file or directory
(env)

然后我意识到终端正在从下面命令中的文件位置删除反斜杠，因为它是一个特殊字符

then I realized that the terminal is removing the anti-slashes from the file location in the commande below because it's a special character

c:/Users/Yourusername/Dev/django_project_boilerplate/env/Scripts/python.exe c:\Users\Yourusername\.vscode\extensions\ms-python.python-2020.6.89148\pythonFiles\pyvsc-run-isolated.py pip install -U mypy 

推荐答案

我在单击安装 ipykernel"时遇到了同样的错误在 VS Code 中尝试使用 Python 交互模式时的​​弹出窗口.

I got the same error when clicking the "Install ipykernel" on the pop-up window when trying to use Python Interactive mode in VS Code.

我的问题是我在 Windows 上运行 VS Code 时将 git bash 作为我的默认 shell，因此无法正确处理文件路径.

My problem was that I had git bash as my default shell while running VS Code on Windows, hence filepaths where not being processed properly.

我通过更改终端的默认 shell 解决了这个问题:

I solved the problem by changing my Terminal's default shell:

1. 输入:ctrl + shift + p
2. 在下拉列表中，选择 Terminal: Select Default Shell
3. 在随后的下拉列表中，选择 Command Prompt C:\...
4. 再次尝试运行交互模式(例如，在一行代码上方添加 #%%，然后单击Run Cell)
5. 现在点击安装 ipykernel"；在右下角出现的弹出窗口中.

现在从 cmd shell 执行安装没有任何问题，并且交互模式工作正常.

The installation now executed from the cmd shell without any problems, and Interactive mode worked fine.
