sudo npm install -g typescript
tsc --init

A few tips in order

• restart the terminal
• restart the machine
• reinstall nodejs + then run npm install typescript -g

If it still doesn't work run npm config get prefix to see where npm install -g is putting files (append bin to the output) and make sure that they are in the path (the node js setup does this. Maybe you forgot to tick that option).

If your TSC command is not found in MacOS after proper installation of TypeScript (using the following command: $ sudo npm install -g typescript, then ensure Node /bin path is added to the PATH variable in .bash_profile.

Open .bash_profile using terminal: $ open ~/.bash_profile;

Edit/Verify bash profile to include the following line (using your favorite text editor):

export PATH="$PATH:"/usr/local/lib/node_modules/node/bin"";

Load the latest bash profile using terminal: source ~/.bash_profile;

Lastly, try the command: $ tsc --version.
