npm install - how to trigger npm task as a post-install hook?

Question

After npm install is run I would like to run

npm run jspm install

I have package.json

"scripts": {
    "postinstall" : "npm run jspm install",
    "jspm": "jspm"
},

This throws an error since npm run jspm install gets passed to node rather than npm. What's the correct way to do this?

@FelixKling because that would make the assumption that jspm (and the proper version of jspm) is installed globally on the system — George Mauer, Sep 10 '16 at 16:10
No, it will pick up the local version if it is installed (afaik). I mean, you have `"jspm": "jspm"` there as well. Why should `"jspm": "jspm"` work differently than `"postinstall": "jspm install"` ? — Felix Kling, Sep 10 '16 at 16:21
@FelixKling hmm...good point, everything in npm scripts is pathed to the `node_modules` directory so yeah that should work. Feel free to make that an answer so I can mark it correct. — George Mauer, Sep 10 '16 at 16:38

There doesn't seem to be a reason to reference the jspm script. You can refer to jspm directly in the postinstall script:

"postinstall" : "jspm install",

for any reason my start process fails because of this line. If I type "jspm installe" as single command on the command line it will work but as postinstall it will fail. Do you have an idea what could cause this behavior? – Ben Jan 20 '17 at 11:34
