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

[helegrod]

All .re files report an error at the first symbol of the file.

Occurred after creating a project with bsb-init app -theme react-hooks

Issue occurs across multiple machines, and over several version of bs-platform and reason-vscode.

Code still builds without issue.

C:\Users\Brothersr\Desktop\WorkBench\ReasonReact\app\node_modules\bs-platform\lib\bsc.exe: wrong argument '3''; option '-bs-jsx' expects an integer.
Usage: bsc <options> <files>
Options are:
  -bs-super-errors  Better error message combined with other tools 
  -bs-jsx  Set jsx version
  -bs-re-out  Print compiler output in Reason syntax
  -bs-gentype  Pass gentype command
  -bs-suffix  Set suffix to .bs.js
  -bs-no-implicit-include  Don't include current dir implicitly
  -bs-assume-has-mli  (internal) Assume mli always exist 
  -bs-assume-no-mli  (internal) Don't lookup whether mli exist or not
  -bs-D  Define conditional variable e.g, -D DEBUG=true

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#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?

@Paosder it is fixed in beta release
