Description

When running ng serve sometimes without explicit change in the code the project gets recompiled multiple times in a row. Sometimes this series end with an error:

The process stops watching for new changes and no further reompilation is hapening. After I stop it and start it again the compilation completes with no errors and it keeps watching for changes, which trigger healthy recompilation.

Hi, thanks for reporting this.

This seems to be related to microsoft/TypeScript#29365

[alan-agius4]

This should be solved in the next release (7.3.8)

The commit that addressed this should be fad7ba9

If the problem persist after upgrading kindly open a new issue.

Thanks

[gozzoo]

OK, thanks!

For me it works again updating to:

Angular 7.2.12
CLI: 7.3.8 + global version
devkit: 0.13.8

And delete node_modules and new npm i

[gozzoo]

I just did full reinstall and the problem persists.

1. I deleted node_modules folder
2. I deleted node_cache folder
3. I did: npm install in the project folder

What's interesting is that the re-compilation is caused by seemingly unrelated events like resizing termial window in VSCode or starting production build in another terminal ng build --prod. Recompilation is oftern triggered by loading the app in the browser. It also happened after I did file search in VSCode.

Not each sporadic recompilation ends with error, but sometimes it does.
