Why is the tsc command not recognized?

Question

typescript

The name "tsc" is not recognized as the name of a cmdlet, function, script file, or executable program.
I get this error when I try to see at least the version, not to mention the compilation, installed via npm, globally.

Answer 1

If you installed it globally via npm or yarn, then it should work right away.
In order for the installed to be pulled up, you often need to restart the terminal, perhaps this is the case.)

Answer 2

npx tsc
