You are all messing with the global installations and -path files. Just a little error might damage every project you have ever written, and you will spend the rest of the night trying to get a console.log('hi') to work again.

If you have run npm i typescript --save-dev in your project - just try to run:

npx tsc

And see if it works before messing with global stuff (unless of course you really know what you are doing)

This answer is specific for iTermV2 on MAC   First of all  I needed to instal as sudo  admin  during NPM install  sudo npm install -g typescript NPM installs the libraries under  usr local Cellar node  lt your latest version gt  lib node modules typescript folder and symlinks at  usr local Cellar node  lt your latest version gt  bin tsc   hence I went    zshrc    bashrc  if you use bash and added  usr local Cellar node  lt your latest version gt  bin to the  PATH     reload the shell profile via source    zshrc   bashrc in your case

None of above answer solve my problem  The fact is that my project did not have type script installed  But locally I had run npm install -g typescript  So I did not notice that typescript node dependency was not in my package json  When I pushed it to server side  and run npm install  then npx tsc I get a tsc not found  In facts remote server did not have typescript installed  That was hidden because of my local global typescript install
