Hi ,
I am also facing the same problem.

while compiling the solution via ng serve -o after angular 5 update this issue occurs.

i have used npm link to link all my modules.

I am also having the same problem very annoying. This failure comes after angular 1.5 upgrade

I am facing aussi the same problem. I run with @augular/cli 1.5.3. The project already compiled successfully once. When I did some modification, the same error shown up. I used the compiled backup source file to run ng serve again. The error persist. This is really an annoying issue.

I tried aussi the 1.6beta version, still getting the same message. Hoping some one can help...

Thanks for reporting this issue. However, this issue is a duplicate of an existing issue #8284. Please subscribe to that issue for future updates.

For those that have Ts files in your node_modules, please read through #8284 (comment). It explains why TS files in node_modules are not compiled.

I had the issue like this after upgrade to CLI .
The issue was fixed with file rename and all links for it in the same lower case. Before the upgrade it was not an issue.
