TypeScript Version: 2.6.0-dev.20171019

Code

Install @types/node.

declare var process: any;

Expected behavior:

Error at declare var process: any;, or the other error should mention it.

Actual behavior:

node_modules/@types/node/index.d.ts(75,13): error TS2403: Subsequent variable declarations must have the same type.  Variable 'process' must be of type 'any', but here has type 'Process'.
