ng install fails with missing module

[filipesilva]

Using the latest master, and trying to install angularfire2 yields the following result:

filipe.silva@DESKTOP-7ND6T3R MINGW64 /e/dev/ideablade/testing/testproj4 (master)
$ ng install angularfire2

I tried to simply do npm install npm on my angular-cli install, but that changes the error to something else that doesn't look much better.

The issue seems to be related with this line.

/cc @jkuri @NathanWalker @jeffbcross

Edit: running ng install ng2-cli-test-lib yields the same results.

@filipesilva try npm link npm. This is sometimes happening on Windows. If npm linking doesn't work and you find a solution maybe please post it. I can try on VM Win7 tomorrow.

[filipesilva]

Roger, that solves it. I'll look into a more permanent solution for this tomorrow.

Thanks for the super fast response btw!

[jeffbcross]

@filipesilva are you on Windows or Mac? npm link npm didn't solve my issue on Mac.

[filipesilva]

I am on windows, but although @jkuri 's fix resolved my issue with ng2-cli-test-lib, I am getting another, different issue with angularfire2

filipe.silva@DESKTOP-7ND6T3R MINGW64 /e/dev/ideablade/testing/testproj4 (master)

Done.

It seems related with this check. It seems to be enforcing the bundling step in the docs.

[jeffbcross]

I think the peer deps warnings aren't causing any issues.

The real issue appears to be these lines: https://github.com/angular/angular-cli/blob/master/addon/ng2/tasks/lib-install.js#L563

Those lines are checking if my package contains angularfire2.ts, and bundles/angularfire2.ts, which the project doesn't contain.

[jkuri]

@jeffbcross try setting the correct $NODE_PATH on Mac.
SystemJS bundles are needed for this to work, also angularfire2.ts should export default var and correlated directives/pipes/... Please check the link @filipesilva provided to make package authentic with this command.

Edit: ng2-cli-test-lib is a good example exporting everything possible

[jkuri]

I can also provide a PR for this library to make package authentic if it will be needed.

[jeffbcross]

I'll close this issue since the original issue is resolved. I opened #188 and #189 as follow-ups.

[jeffbcross]

Thanks for the help @jkuri and @filipesilva!
