  I am not sure if it is a bug in the builder but I don't know how to debug it...

• What is the current behavior?
  When I build a lib with an external dependency, I have an error:

• What is the expected behavior?
  To not have an error :-)

Maybe it's caused by the dynamic-form library but I don't know why, so I can't open an issue...

It works very well with other libraries and thanks again because this project has a very good enterprise vision !

[shlomiassaf]

Yes, that's strange...

If you remove that lib it all works?

[shlomiassaf]

Looking at #6 got me thinking...

Did you install these 3rd party libs in node_modules within the package directory (as opposed to node_modules in the root of the project)

[jogelin]

If I remove it, indeed it works...

Yes it was the case, like I said in the #6, I am doing that with other libraries and it works...

So I tried to put those dependencies in the devDependencies of the root project but I have a lot of errors:

I think it is because it tries to compile all .ts files of this library but it is not in the lib folder anymore...
We shouldn't publish ts files when we make a library...should we ? How can I ignore those files ?

Hi @jogelin, I'm having a similar issue, did you find a solution for the TypeError: Cannot read property 'path' of undefined at TsickleCompilerHost.getSourceMapKeyForSourceFile error?

[jogelin]

Hi @DDeis, I am sorry but I can't help you. I did not solve this issue...

[DDeis]

Thanks for the feedback @jogelin, for my part the issue happens because the TsickleCompiler host was trying to resolve the index.ts of the failing library instead of the typings file (index.d.ts).
