Issue when using yarn link and @types types

[raybooysen]

TypeScript Version: 2.0.3

I have two projects, ProjectA and ProjectB. Both projects have @types/react installed. If ProjectA is linked to ProjectB via yarn link, ProjectB will start to complain when building:

node_modules/@types/react/index.d.ts(7,21): error TS2300: Duplicate identifier 'React'.
node_modules/@types/react/index.d.ts(2449,13): error TS2403: Subsequent variable declarations must have the same type.  Variable 'a' must be of type 'HTMLProps<HTMLAnchorElement>', but here has type 'HTMLProps<HTMLAnchorElement>'.

Since there is @types/react in both projects, this seems to cause issues.

@raybooysen do you run into the same issues if you used npm link?

This is fixed in TS 2.1 I believe

@raybooysen can you give it a try with typescript@2.1.4 or typescript@next? if issue still persists please share a sample project we can use or some detailed steps, including versions of the @types packages to be able to reproduce this locally.

First link then install.

the problem is the link, tsc seems to be resolving the symlink instead of using it as-is (see #9566 and #6496)

same error, dont know what to do
i linked my project with yarn whetever i exclude or delete the linked node_modules, always get an error based on

ERROR in [at-loader] ./node_modules/@types/hammerjs/index.d.ts:9:5 
    TS2300: Duplicate identifier 'export='.
