Cannot find name 'Diagnostics'

Question

I've cloned the Typescript repo and am looking at the code, but it is full of this error:

Cannot find name 'Diagnostics'

on lines that look like this:

Diagnostics._0_expected

I can see a JSON file in the same folder, with a list of diagnostic messages, but how do I generate this file?

Answer 1

You probably should build the library first.
Please refer to the building section in the readme file of your specific version (The build system used to be jake and now it is gulp).
All you need to do is:

1. Install the build system globaly (jake/gulp)
2. Run npm install
3. Run jake local or gulp local (according to the build system).
