Description / Steps to reproduce / Feature proposal

Just created a new lb4 app with lb4 app command.

Current Behavior

npm start does not work as expected and I can't run the app. This is the output:

> noghtechin@1.0.0 prestart /Users/mamal/Projects/JS/noghtechin
> npm run build


> noghtechin@1.0.0 build /Users/mamal/Projects/JS/noghtechin
> lb-tsc

And this is the output of lb4 -v:

I already saw #1405 but it seems a bit old and my current version of lb is far newer from recommended version there. 🤔

I also have the same problem. VSCode is reporting multiple times that there are no exported functions. Looking at the modules in /node_modules/@loopback it seems that they are trying to export from a non existing directory.
For example @loopback/context/index.d.ts is
export * from './dist8';
but the directory structure has

@loopback/context/dist10
@loopback/context/src
@loopback/context/CHANGELOG.md
etc

with no dist8 folder.

Please try again with @loopback/cli@0.20.2.

[DouglasWebster]

Thank you, examples and new projects seem to be building correctly now 😌

[mamal72]

@virkt25 Thanks! It's working now! 🙏

I'm going to close this issue as it seems 0.20.2 is published at npm.
