无法让 VS Code 从 launch.json 传递 arguments 到 Python

Question

I cannot figure out how to get VS Code for Mac to start debugging my Python script with the arguments I have defined in my launch.json file by using the debug button to the right I have circled here. The only way I can get my arguments to be recognized is if I go to the menu and select "Run|Start Debugging" or if press F5.

How do I tell VS Code to use my launch.json file when using that button???

If you look at the answer from Sourya Dey at the link below, this is what made me write this. There must be some simple setting or step missing to link that button to F5. It appears others are also confused about this.

Visual Studio Code: How debug Python script with arguments

For clarity, here is my launch.json file which works as expected with F5. It does not work with the button I have circled in red above

Answer 1

In your Python code, you can call debugpy.breakpoint() at any point where you want to pause the debugger during a debugging session. I recommend reading this document for more information. You can also add a manual breakpoint by clicking the left part of the line numbers shown on the side of the source code window. When the program stops at the breakpoint during debug, you can see the current value of the variable when you move the cursor over the variable.

To debug Python code in VS Code, install the following plugins:

• Python
• Python Preview

Answer 2

I filed a bug with the Microsoft VS Code team regarding this issue and they sent me over to the Microsoft Python extension group. I then filed a bug there referencing the VC Code ticket and it was immediately assigned for "area-debugging triage". I presume this will be fixed in a later version (I am on 1.63.2)

First, it is not obvious where this button comes from. I have noted this issue as well with Microsoft so they can improve their documentation. When you install VS Code with no extensions, this button is not present. But as soon as you load your first Python file, Microsoft urges you to install the official "Microsoft Python Extension" and then the button shows up. In my mind, I assumed this was a native VS Code button that showed up when you had a language debugger installed. When I removed all extensions, except the Microsoft Python extension, I was convinced this was part of VS Code.

The answer above incorrectly states that this is the correct behaviour for the button. It is not. Microsoft has confirmed this and if you read issue #2338 ("Documentation for python.terminal.launchArgs is unclear") there is a response in there stating:

"Unfortunately that's just how vscode works. When debugging all settings are read from launch.json and non-debugging settings.json is used This applies to all languages (extensions) in vscode."

So for now, there is nothing much to do other than wait for this to be fixed.

Lastly, for those who are wondering why I wanted to use that button in the first place. For the most part, I use keyboard mappings to start debugging when I am inside VS Code. But for this particular project, I was going to other external windows and when coming back to VS Code, since I was already using the mouse, I just wanted to click there out of convenience. I don't keep the debug tab open which also has a debug button that works as intended.
