I’ve got a node express app written in typescript. Build is failing in Render during deploying the web service. In my local system build is successful and server is up and functioning.

This is not the tsc command you are looking for

To get access to the TypeScript compiler, tsc, from the command line either:

- Use npm install typescript to first add TypeScript to your project before using npx
May 18 04:36:43 PM
- Use yarn to avoid accidentally running code from un-installed packages

==> Build failed 
Basically npm install is not installing typescript. How do I resolve the issue?
