Installation fails on postinstall

[benediktwerner]

When installing with npm install -g bs-platform on WSL I get the following error:

/root/.npm-global/bin/bsb -> /root/.npm-global/lib/node_modules/bs-platform/lib/bsb
/root/.npm-global/bin/bsc -> /root/.npm-global/lib/node_modules/bs-platform/lib/bsc
/root/.npm-global/bin/bsrefmt -> /root/.npm-global/lib/node_modules/bs-platform/lib/bsrefmt

Any ideas how to fix this?

bucklescript works on windows natively -- I will see if I can reproduce it on WSL
btw, there are lots of bugs in npm5, we came to it lots of times, can you try also on npm4 and yarn

[bobzhang]

feel free to reopen it if you still have such issue, or anyone see this happen again

I'm having the same problem, while trying to follow this guide. However, instead of WSL, I'm installing bs-platform inside a Ubuntu 16.04 docker image.

> bs-platform@2.1.0 postinstall /root/.npm-global/lib/node_modules/bs-platform
> node scripts/install.js

module.js:540
    throw err;
    ^

As you can see, both @benediktwerner and I mkdir this directory ~/.npm-global to fix the NPM permission issue, which explains why the folder appeared in the error log.

Any idea why this is happening? Thanks!

UPDATE:
Oh it seems the script is there, but npm will not execute scripts when running as root (as mentioned here. Turns out upon being unable to execute the script, npm for some reason showed the Cannot find module error instead.

TL;DR: just run npm install -g bs-platform --unsafe-perm and it should work.

After an entire day of trying to get bucklescript in a container(debian) running as root.
The above update finally worked!
npm install -g bs-platform --unsafe-perm

node -v :- 8.9.4
