BSC.exe: Wrong Argument. -bs-jsx expects an integer about vscode-reasonml

[tomcase]

This seems to be an issue on Windows, and I ran into the same problem. The way I solved it is by going into your .merlin auto-generated configuration file, and removing the quotes from around the FLG -ppx 'C:\Users\Brothersr\Desktop\WorkBench\ReasonReact\app\node_modules\bs-platform\lib\bsppx.exe -bs-jsx 3'

So mine looks like this:

FLG -ppx C:\Users\tom\dev\myproj\node_modules\bs-platform\lib\bsppx.exe -bs-jsx 3 

The issue comes down to using quotes to guard against spaces in windows path names. It lumps the second ' in with the integer at the end (3).

This is probably more of an issue with the bucklescript compiler than with this extension. See: rescript-lang/rescript-compiler#3588

I know this issue was opened two weeks ago, but I came across it while investigating the same issue, so I'll leave the answer in case anyone else does the same.

This issue still occurs in windows 10 and it seems not resolved yet. Any progress?
