'react-scripts start' does not work on linux (WSL) #9644
Description
Describe the bug
On linux (WSL) npm run start fails with the following error
spawn powershell.exe ENOENT
Not sure why its trying to spawn powershell on Linux but this seem to have been introduced from version 3.0.0 of react-scripts. The workaround is to downgrade react-scripts to 2.1.8
This is reproducible on a fresh install using latest npm version 6.14.8 and latest nodejs verison 14.10.1 (also reproducible on 10.x)
Did you try recovering your dependencies?
Reproducible on a fresh install so unlikely its related to corrupt dependencies.
