Additionally, allow setting the "typescript_tsdk" using relative paths as the .sublime-project can be shared across machines so "typescript_tsdk": "./node_modules/typescript/lib" is likely to be the most widely used path.

"typescript_tsdk": "./node_modules/typescript/lib" works for me in my user settings, to enable per-project specification. I'm on Ubuntu 16.10.

EDIT: actually, it doesn't. It seemed to work but I get the following in the ST console.

Exception in thread Thread-4:

any updates on this one? It's a real blocker for me

I'm also interested on getting multiple TypeScript versions to be used in projects. I have some legacy projects which work with the bundled 2.2.x version, but for newer projects which use TypeScript 2.4.x especially async/await and string Enums give headache. I manually updated latest TypeScript to TypeScript-Sublime-Plugin to overcome the issue, but it would be nice if there would be a configuration option to at least override the bundled version with something newer globally.

want to ping this topic! Really blocks usage with st3

Is there any update on this? This is a must have feature for me.

I see the task is closed but I'm not quite clear on the outcome. From my testing, it seems that it supports a global user setting for typescript_tsdk which references a project-relative path (i.e. "node_modules/typescript/lib"), but does not support a project-specific typescript_tsdk in .sublime-project. Can you confirm?

I was wondering why .sublime-project is not supported, but maybe it's not so important since a project-relative path can be specified in the global setting. I tend to prefer project-specific settings.

I'm also having problem setting typescript_tsdk in .sublime-project. Setting typescript_tsdk only works as a global user setting.
