Some errors following the tutorial.

[BBaysinger]

Hi Lucas, thanks for the tutorial. I was trying to follow it, and I ran into some issues. I got past a couple of them.

After doing the Installing gulp section, I ran gulp build and got:

[11:30:33] Failed to load external module ts-node/register
[11:30:33] Failed to load external module typescript-node/register
[11:30:33] Failed to load external module typescript-register

[11:30:35] Finished 'compile-typings' after 1.6 s

...and some other stuff.

I fixed that by running npm install ts-node --save-dev.

Then I ran into:

/Users/bradley/Downloads/MyAngularLibrary-master/node_modules/ts-node/src/index.ts:319
          throw new TSError(formatDiagnostics(diagnosticList, cwd, ts, lineOffset))

I got past that by using npm install @types/node --save-dev.

Now I try to run gulp build, and I get:

Your tutorial is the latest info I can find on building a component library that can be consumed by Angular-CLI. The other ones I found are a bit dated. So this is a valuable tutorial. It would help me so much to see this working. Please let me know what I am missing.

I'm seeing all the same issues as @BBaysinger. Any feedback would be very helpful!

Seems to work just fine for me if I take the arguments out of the tsProject.src() call

[BBaysinger]

If that doesn't work, here's another way to create a component library that can be consumed by Angular-CLI. It's a workaround until there is direct support for libraries:
