Latest version of jQuery for TypeScript is throwing syntax errors? [duplicate]

Question

I am almost 100% sure I am doing something wrong to cause this as I am incredibly new to TypeScript and have been updating an old codebase.

When I update jQuery to the latest version I get the following errors when I try and build my project using grunt.

/jquery/jquery.d.ts(279,40): error TS1005: ',' expected.

/jquery/jquery.d.ts(279,61): error TS1005: '=' expected.

/jquery/jquery.d.ts(279,64): error TS1003: Identifier expected.

/jquery/jquery.d.ts(279,97): error TS1005: ',' expected.

/jquery/jquery.d.ts(279,118): error TS1005: '=' expected.

I have shortened the paths and not given every single line, but there are a lot of them.

I am building this using grunt-ts and it seems to be using tsc v1.0.1 – I am unsure where this would be set I am just going by the output when it attempts to build.

The new version of the jquery.d.ts file uses syntax that is new to TypeScript 1.4. Either upgrade your compiler or downgrade to an earlier version of the .d.ts file[0]. There's a "1.3" branch on DefinitelyTyped specifically for pre-1.4-compatible .d.ts files.
