My `create-react-app` is not working

So, when starting my project it says this:

internal/modules/cjs/loader.js:670
throw err;
^
Error: Cannot find module '/app/node_modules/react-scripts/bin/react-scripts.js'
at Function.Module._resolveFilename (internal/modules/cjs/loader.js:668:15)

at Function.Module.runMain (internal/modules/cjs/loader.js:877:12)
at internal/main/run_main_module.js:21:11

And I can’t update my node.js:

node v11.14.0, with pnpm
Installing...
Performing headless installation
ERROR  EACCES: permission denied, symlink '../.registry.npmjs.org/@babel/core/7.8.4/node_modules/@babel/core' -> '/rbd/pnpm-volume/e1de37d6-78dd-4f3b-907c-f76dd0867acd/node_modules/@babel/core'

While in the console updating node it says this:

Please, could somebody help me with this?

Thank you!

Hi there - sorry you were running into this issue. We’re working on a more systematic fix for this, but in the meantime this error can be resolved by running the following command in the project terminal:
enable-pnpm
This fixes the broken symlink that you can see in the logs. I ran this for you already and the project was able to compile.
Thanks and please let me know if you have any further questions!

Hey! Thanks for the help. I hope that you will find the fix pretty soon. It’s sad to see errors popping up without a reason.
And again, thank you for your help!
