How to update TypeScript to latest version with np

Question

Currently I have TypeScript 1.0.3.0 version installed on my machine.
I want to update it to latest one i.e. 2.0.

How to do this with npm?

Answer 1

Try npm install -g typescript@latest. You can also use npm update instead of install, without the latest modifier.

Answer 2

Just use the command # npm update -g typescript
For update all global installed module, Use this command# npm update -g

Answer 3

On Windows open command prompt (cmd)

Recommended:

npm install -g typescript@latest

This will install the latest typescript version if not already installed, otherwise it will update the current installation to the latest version.

And then verify which version is installed:

tsc -v

If you have typescript already installed you could also use the following command to update to latest version, but as commentators have reported and I confirm it that the following command does not update to latest (as of now)!

npm update -g typescript@latest

Answer 4

If you are on Windows and have Visual Studio installed you might have something in your PATH that is pointing to an old version of TypeScript. I found that removing the folder "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\" from my PATH (or deleting/renaming this folder) will allow the more recent npm globally installed TypeScript version of tsc to work.

Answer 5

You should be able to do this by simply typing npm install -g typescript@2.0. If this does not work, I am beginning to wonder what version of node and npm you are on. Try node -v and npm -v to find these out. You should be on node >4.5 and npm >3
