VS Code Debugger：导入错误，没有名为scrapy的模块

Question

I am able to run all the scrapy spiders on vs code without any error. But when I try to run the debugger, it raises an exception

No module named scrapy

I am on MacOS. I can properly run scrapy commands from the terminal as well.

Answer 1

Try running your script from cmd in debug mode with

python -m debugpy --listen 5678 --wait-for-client ./__main__.py

Make sure to install it using python -m pip install debugpy

and then configure a launch.json file in the debugger to attach to the python script listening on port 5678

{
  "name": "Python: Attach",
  "type": "python",
  "request": "attach",
  "connect": {
    "host": "localhost",
    "port": 5678
  }
}

The complete file will look something like this

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Attach",
            "type": "python",
            "request": "attach",
            "connect": {
                "host": "localhost",
                "port": 5678
            }
        }
    ]
}

After that set the breakpoints in your program and start the debugger from vscode

Also check if the version running during the debug is the same used normally, just create a blank file with the following content

import sys

def main():
    print(sys.version)

if __name__ == "__main__":
    main()

the following will print something like

3.6.9 (default, Jan 26 2021, 15:33:00) \\n[GCC 8.4.0]

Also check from the statusbar at the bottom of vscode if you have the right python version selected.
