Doesn't seem to work for "prepack" lifecycle script

[Venryx]

I added shx as a dev-dependency for my fork of an npm module here: https://github.com/Venryx/mst-decorators

However, even with it in the dev-dependencies, when I run npm install Venryx/mst-decorators in another project, I get this error:

PS C:\Root\Apps\@V\CDL\Client> npm install Venryx/mst-decorators

> mst-decorators@2.1.1 prepack C:\Users\Stephen\AppData\Roaming\npm-cache\_cacache\tmp\git-clone-4f5c52b7
> yarn clean && yarn cjs && yarn esm

yarn run v1.19.1
$ shx rm -rf cjs esm

The problem seems to be that the dev-dependencies are only installed after running npm install in the mst-decorators folder -- not merely when my mst-decorators fork is being installed through the npm "install from github repo" function.

Any solution to this?

npm install doesn't install the package's dev deps. Furthermore, prepack should only run before builing a tarball, so not as part of the install (https://docs.npmjs.com/misc/scripts).

So it's weird that it tries to run prepack without the dev dependencies.

I'm not familiar with prepack, but if this is an npm script you expect dependent modules to run, or as part of running npm install, then you need to add shx to the regular dependencies rather than dev-dependencies.

I don't think there's anything for shx to do here, so I'm going to close this out. Please ping this if I've misunderstood.
