Question

I want to install typescript, so I used the following command:

npm install -g typescript 

and test tsc --version, but it just

Answer 1

1. Check your npm version

2. If it's not properly installed, then install it first

3. run this command npm install typescript -g

4. now tsc <file_name>.ts

5. It'll create a corresponding .js file. eg <file_name>.js

6. now try node <file_name>.js

Answer 2

I solved this on my machine by just running sudo npm install in the directory that I was getting the error.

Answer 3

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.

Answer 4

I know this is an old question, but I had this same problem on Ubuntu 19.10 LTS.

To solve this I ran the following command:

$ sudo apt install node-typescript

After that, I was able to use tsc.

I hope it helps :)

Answer 5

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 nite 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 ofc you really know what you are doing)

Answer 6

This answer is specific for iTermV2 on MAC

1. First of all, I needed to instal as sudo (admin) during NPM install

   sudo npm install -g typescript

2. NPM installs the libraries under /usr/local/Cellar/node/<your latest version>/lib/node_modules/typescript folder and symlinks at /usr/local/Cellar/node/<your latest version>/bin/tsc

hence I went ~/.zshrc ( .bashrc, if you use bash)and added /usr/local/Cellar/node/<your latest version>/bin to the $PATH.

3. reload the shell profile via source ~/.zshrc (.bashrc in your case)
