Build fails when using ember-cli-ramdisk

[IanVS]

I created an issue at ember-cli-ramdisk [https://github.com/ExpressCheckout/ember-cli-ramdisk/issues/8], but thought you might like to know about this as well. When using that addon, I am unable to import modules. For example if I try to import moment from 'npm:moment'; I get the error:

Error: Cannot find module 'moment' from '/mnt/EmberCliRamdisk/borrowers/core_object-input_staging-HpoS1dc8.tmp'

I have no idea what the actual problem is, which is why I brought it up in both repos.

Browserify is picky about where your tmp folder lives relative to your node_modules folder. If you can mount the actual ramdisk at your-app/tmp instead of just symlinking it, that would probably solve this. Alternatively, you could try symlinking your node_modules folder into the real ramdisk location, so that code being built there can find it via normal node rules.

@ef4, moving node_modules to /mnt/EmberCliRamdisk//node_modules/ and symlinking back to my project folder seems to be working . . . as long as I don't reboot. :-o

I think I'll just move my Ember project folders to my HDD and avoid the hassle. Thanks for explaining the cause.

[stefanpenner]

@ef4 we have plans to move the tmp folder outside of the project. We will likely need to fixup how ember-browserify works for that. Can we inform browserify of the correct node_modules root/package.json to review?

[ef4]

As far as I know it's not easy. browserify is trying hard to maintain normal node semantics. node is really picky about only using the node_modules hierarchy.

So I think the right thing to make sure that the project's node_modules is available within the build tree that gets passed to browserify. A symlink should suffice.

[stefanpenner]

@ef4 if symlink works, then fantastic. But does leave our windows friends in a bad spot.

I wonder if we can bend substacks arm

[IanVS]

It worked for me with symlinking node_modules. How would this work for multiple projects if tmp and node_modules both live outside the project folder? I like that ember-cli is self contained as it is now.

[stefanpenner]

node_modules will remain in the project, tmp will not. It is a hazard for editors and other tools watching `tmp/*

[stefanpenner]

@ef4 this will also break with broccoli v1, one thing we could do is make a custom browserify-tmp dir in the project root, thoughts?

[stefanpenner]

This will actually need to be revisited, when broccoli 1.0 happens and tmp moves to system tmp. The solution is to symlink (and junction for our windows friends) in node_modules to the basedir of browserify.
