Please set SHELL_EXECUTE_FLAG env variable.

Dear all,

last two days, I am trying to run
"./node_modules/.bin/concurrently --raw --kill-others \"yarn run build -- --watch\" \"yarn run nodemon --harmony | bunyan -o short -l trace\" - but after all solutions proposed herein "Issues" I still keep receiving:

Error occured when executing command: yarn run build -- --watch
Error: Unable to detect platform shell type. Please set SHELL_EXECUTE_FLAG env variable.

I've tried to use all 3 available versions of spawn-default-shell, also tried to set up env variables. Nothing.

Please advice.

Start by reproducing the reported concurrently command and inspect how spawn-default-shell detects the platform shell and uses SHELL_EXECUTE_FLAG. Compare the available spawn-default-shell versions mentioned in the issue; the work is done when the reported command runs without the shell-type detection error.
