问题
I'd like to find a free solution to debug vbscripts, and I tried Visual Studio 2019 Community Edition. I did the very basic installation with only one additional component, the Just-In-Time debugger. I ran all the following steps as administrator.
I have created the file Script2.vbs with this very simple script:
a=1
b=1/0
c=1
I started the command line (cmd.exe) and entered cscript.exe /x "C:\...\Script2.vbs
The script is executed and fails as expected at line 2 but
the problem is that the Just-In-Time debugger doesn't start.
(I expect the popup which is below "The Visual Studio Just-In-Time Debugger window appears" in this Microsoft article)
I have found in this question about the previous version of the Community Edition that there should be the option "Script", but I don't have it:
Note also that if I try to start the script from Visual Studio Community, the menu Debug > Start debugging is grayed out:
My main question is:
Is the feature of debugging scripts turned off with Visual Studio Community Edition?
(which leads to the second question: is there a solution to debug VBS scripts for free?)
回答1:
If you are still interested, there is a way to fix Visual Studio Community. It's likely some missing pre-requisites. Therefore you need to "Modify" the installed options and find "Script" debugging options in the Individual Components setup.
For example this is my minimum set of components.

You can download the VBS debugger from my OneDrive https://1drv.ms/u/s!AvqkaKIXzvDieQeOGgxLJICZ-uY?e=3r5B91
It is called scd10en.exe.
It has disappeared from MS's web site.

I installed Visual Studio 2019 Community Edition on a new installation of Windows 10 and experienced this same problem.
My initial installation of VS included just the ".NET desktop development" workload.
Once I installed the "Python Development" workload, the script option appeared under the Just-In-Time debugging options. No other changes were required.

peregrinus gave the right answer so I Accepted it. Here are the details :
My test was with Visual Studio Community 2019, version 16.7.7.
I installed Visual Studio from scratch with only the following 3 minimal components
- Compilers, build tools, and runtimes
- C++ CMake tools for Windows
- MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.27)
- Debugging and testing
- Just-In-Time debugger
- Compilers, build tools, and runtimes
I ran the VBS with the option
/xto start the debuggerCScript.exe /x Script2.vbs
A popup appears to select the Just-In-Time Debugger, I kept the options as proposed and pressed OK
The VBS code is shown, the debugger stops at the first line of the script
I can add a breakpoint at line 2, watch the variable
a, and if I press Continue (F5), that stops at the breakpoint, etc.
NB: for information, I now see the third debugging option "Script" in VS menu Tools > Options:
