I'm using the angular-cli with version 1.2.7, by default, it create new angular apps with typescript 2.3, but now I want to use some feature of typescript 2.4.
I tried to update the typescript in package.json, remove all node_modules, and npm install again, but this seems not work.
How can I config my project, so that angular-cli can use typescript 2.4 instead?
package-lock.jsonfile, and try to install again
