Not exactly sure what's happening, I guess node doesn't let you have a node package globally installed that conflicts with a local package's version?

[tracymedcalf]

I'm having the same problem. @Schmavery any suggestions?

[Ctrlmonster]

Hey, I'm running into the same problem. Any news?

[Schmavery]

The long-term answer is that we've been working to try and get the changes in bsb-native upstreamed into bucklescript here: https://github.com/BuckleScript/bucklescript/pull/3762

I'm not sure what the specific bug is in this case, unfortunately the only workaround I'm aware of currently is not globally installing bs-platform.

[bsansouci]

Hey all! Sorry about this, I'm guessing you're all on linux? We're working on figuring out what's going on to see if we can fix it soon

[spike7638]

Any progress here? I'd love instructions for the "not globally installing" solution if that is something that would get me to a working state...

[bsansouci]

Hey @spike7638 sorry for the long-ass wait. So I’d recommend nuking your global install of bs-platform by doing npm global remove bs-platform and then install bsb-native locally: npm install bsb-native@4.0.7000 That version should work better than the latest.

[spike7638]

Thanks...I'll give that a try. And thanks for the details -- I'm still learning the arguments/options to both npm and bsb. :(

[Ctrlmonster]

Sorry for the delayed answer. Thanks for the workaround. And yes, I'm on Linux. Cheers

[spike7638]

OK. I'm trying once again Just for the record, I'm on a Mac, v 12.0.1. Using your advice from April 3, combined with what worked for me a while ago (see Dec '19 discussion in https://reasonml.chat/t/is-reprocessing-alive/2045/4), I tried this:

% npm uninstall -g bsb
% mkdir foo
% cd foo
% git clone https://github.com/bsansouci/reprocessing-example.git
% cd reprocessing-example
% npm install bsb-native@4.0.7000
> bsb-native@4.0.7000 postinstall /Users/jfh/Desktop/foo/reprocessing-example/node_modules/bsb-native
> node postinstall.js

/Users/jfh/Desktop/foo/reprocessing-example/node_modules/bsb-native/postinstall.js:22
let version = JSON.parse(fs.readFileSync("package.json")).version;

and got the results you see. Sadly, everything related to Javascript is a mystery to me, so I have no idea what's going on here. But I also tried following the instructions in the README (https://github.com/bsansouci/reprocessing-example/blob/master/README.md) and failed in essentially the same way. It might improve the Readme slightly if, after the git clone, you had us change directory (cd reprocessing-example/) before running npm install . But that's clearly not the main problem here.
