Install NodeJS, and then check the version numbers of node and npm on the command line. If there are no problems, talk about installing babel

Remember to select "Add to PATH" when installing Node, so that modules installed through npm install -g can be run directly on the command line (it seems to be selected by default, it is best to check)

Check after installation is complete

Then install babel-cli

npm install -g babel-cli

Finally, use babel --version to check the version of babel. Once found, there will be no problem.

Put out the error message next time. If there is no error message, who knows the reason for the error.
