This is my .eslintrc.yml configuration
env:

Cuz I have searched the problem and it should be EMCAScript version,
but I tried changing it and it didn't work.
I've checked my macOS is 10.12. and here's my package.json

Does anyone know how to solve this problem ## ?

Answer 1

on your first problem - the sample.js test script - you have copied the Unit Test script contents into lib/sample.js and that is why you have your problems - ie 'const' error - that file is the Transaction Processor functions script. You should (as per the Developer Tutorial) paste the Unit test script into the file located at test/sample.js. I think perhaps the fact that the filenames (in both 'lib' and 'test' subdirectories) are the same, has caused some confusion - think I will get that changed to improve user experience. The other Angular error (mentioned earlier) still stands.
On your second posting (Angular module errors). A local Composer playground install has dependencies on Angular (note the Developer guide uses the online playground). Check out package.json for that list of angular dependencies. Doesn't look like your playground installed correctly, if its showing missing dependencies (#angular/core etc) Suggest to clear down docker ps -aq | xargs docker rm -f and docker images -aq | xargs docker rmi -f (warning: clears down all docker containers in your dev environment) then install it (as a non-privileged user) using the one-liner - ie npm uninstall -g composer-playground - installs playground in a docker container using the command curl -sSL https://hyperledger.github.io/composer/install-hlfv1.sh | bash .

This is what npm list command returns
