I want to install typescript, so I used the following command:
npm install -g typescript
and test tsc --version, but it just show 'tsc command not found'. I have tried many ways as suggested in stackoverflow, github and other sites. but it doesn't work. How could I know typescript is installed and where it is.
my OS is Unix, OS X El Capitan 10.11.6, node version is 4.4.3, npm version is 3.10.5
