Answer 1

It seems that there should be a missing script command called clear, please post your package.json

Supplement:

I see, you see the clear command is like this: "clear": "rm -rf build; mkdir build;",, and your running environment is windows’s cmd. What a tragedy, these commands like rm cannot be used! ! !

Recommendation:

If

is installed with git, you can use git bash to run it. Give up your cmd.

can also install Cygwin (which is also a command line environment that imitates linux shell), give up your cmd

Answer 2

It is recommended to develop nodejs under Linux, you can use virtualbox to create a virtual machine...

Answer 3

MING64 try changing it to this, I feel like you are recognizing clear: as a command

"start": "npm run clear && webpack-dev-server --config webpack.config.dev.js --port 4000 --host 0.0.0.0 --inline --hot --devtool eval --progress --color --profile"
