VS Code - 使用 Conda/Pip 安装 autopep8 时出错

Question

In my VS Code, I got the Python extension running, Python 3.6.1 and Anaconda3 installed. When I copy and paste some code, VS Code asked me to install autopep8. When I press "Yes", it shows a box as .

First I chose "Install using Conda". Next, the following error message pops out and it failed to properly install autopep8:

PS D:\Python> conda activate base

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.

To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - cmd.exe
  - fish
  - tcsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.


PS D:\Python> & conda install --name base autopep8

I don't understand what the message means. Can anyone help me?

Note: Here's all the paths I've included in the PATH:

Answer 1

Ok I figured the solution to this problem. The root cause is that my Powershell is not configured to allow scripts from running in my system. Here are the steps if anyone has this problem too:

1. Launch Powershell as administrator
2. Set-ExecutionPolicy -ExecutionPolicy Unrestricted and pick Y
3. Within Powershell, type conda init powershell and run
4. Re-open VS Code. Then copy and paste some Python code in the .py file
5. At the bottom right corner, VS Code will ask whether to install autopep8. Choose Yes.
6. VS Code will then automatically run some Powershell commands. This should work now

Answer 2

Your installation under conda failed because you have not set up your shell to use conda. The instructions are a little down in the error message on how to set this up:

To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - cmd.exe
  - fish
  - tcsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.
