NPM install issue - bson module didn't build

[ghost]

I am reporting this issue for the records mostly - in case it will lineup with another thread one day...

Building a new MEAN stack project from IDE every module dependencies in package.json file were installed from Run As... > npm install but one: mongoose.

mongoose depends on mongodb that depends on bson module: the bson module didn't build from IDE therefore mongoose installation failed.

What let me think this is not a module but an IDE issue is quite simple: $ npm install from a command line is working just fine.

That is quite possible, because when running npm install from within Eclipse, Java runs in process environment, that is different from OS shell. (I know now better after making simple Maven and Gradle plugins for Eclipse)

What is needed is to know what new process environment lacks, it may be some environment variable

Please add postinstall script in package.json and compare

    "scripts": {
        "test": "echo \"Error: no test specified! Configure in package.json\" && exit 1",
        "postinstall": "node pev.js"
    },

pev.js

console.log(process.env);

no more others ideas so far

pev.js was never called: looks like NPM exits before reaching it - is this making sense?

I wonder how npm install was implemented in the first place: will it be possible to send it to OS shell instead? I could be wrong but it actually rings a bell: is this not quite similar to an express 4 project generator to be run from OS shell we discussed weeks ago?

to send it to OS shell instead?

Just try to lunch other process from Node and Java and you will see that it will run in bare environment quite different from OS shell. OS shell is cmd on windows.

Try check if package.json has e.g. preinstall option.

The Java code for launching npm is old https://github.com/Nodeclipse/nodeclipse-1/blob/master/org.nodeclipse.ui/src/org/nodeclipse/ui/npm/LaunchConfigurationDelegate.java and it lacks environment variable handling I added for Node.js

But before blindly adding more environment variables, it would be nice to have some reference docs... What is minimal and needed for npm to run ?

I don't see added value in this log

@nodeleaf I have added similar handling on envVar to npm launch. But I am not testing it against bson module.

So once 0.18 is released, we can return and check this issue.
