Re: Node and NPM don't work properly on some LPARS?

Aaron

If you are on 0.12.7 it would be interesting to hear how this little test runs on your box: https://gist.github.com/kpturner/0c7104b32ecca7689fc0

You just run "node main.js" and the main process fires up a worker child and then repeatedly asks it to convert a string to upper case on a 1 second interval.

On our servers on 0.12.7 this fails immediately because the child process gets terminated for no logical reason.

Our problem may not be related to node at all of course, but something odd on the LPARs that do not work.

Cheers
Kevin

OK - well we have reported two main issues:

1) A node child process should not just end unless it is a) killed or b) it runs process.exit()
Our simple test code shows this failing in our duff LPARS, but OK on others with earlier versions of node
2) When "npm install" runs it caches its packages in your local .npm folder. After that, it cannot access its own cache and every subsequent "npm install" fails with "uid must be an unsigned integer". You have to run "npm cache clear" before every install to make it work!

I have 0.12.7 installed but haven't experienced that (yet). I also have a boatload of perzl stuff in my PATH and LIBPATH so I don't consider my environment very "stock" at this point.

Even more bizarrely, forked child processes just end straight away.
They really do seem to have made a complete mess of it in v0.12.7.
V0.10.5 seems fine.

The other oddity is that it seems unable to locate dependency
packages
at run time, even though they are all there under the top level
node_modules folder.

Could paste the results of the following?



$ ls -all /home/kturner



5250> DSPAUT OBJ('/home/kturner/.npm')

Back to IBM for this one. After the first install of a package,
npm

creates /home/kturner/.npm but cannot access it afterwards when you

try to install additional packages.

No clue why yet, as the authorities look OK.
