@types/requirejs Variable 'require' must be of type 'NodeRequire'

[michelle-burton]

• I tried using the @types/requirejs package and had problems.
  Error from console:

node_modules/@types/requirejs/index.d.ts
(416,13): error TS2403: Subsequent variable declarations must have the same type.  Variable 'require' must be of type 'NodeRequire', but here has type 'Require'.

typescript error -

in @types/requirejs/index.d.ts
ln416 declare var require: Require;

And in @types/node/index.d.ts
ln73 declare var require: NodeRequire;

Thanks

Michelle

• I tried using the latest stable version of tsc. https://www.npmjs.com/package/typescript
  "typescript": "2.2.1",
• I have a question that is inappropriate for StackOverflow. (Please ask any appropriate questions there).

Same Problem here with error message with different order (using webpack1 and ts-loader)

node_modules/@types/webpack-env/index.d.ts
Subsequent variable declarations must have the same type. Variable 'require' must be of type 'Require', but here has type 'NodeRequire'.

And node_modules/@types/node/index.d.ts
error TS2403: Subsequent variable declarations must have the same type. Variable 'require' must be of type 'Require', but here has type 'NodeRequire'.

But i also get

error TS2306: File '/node_modules/@types/requirejs/index.d.ts' is not a module.

UPDATE: if i use at-loader i get the same error as cyandream:
ERROR in [at-loader] node_modules/@types/requirejs/index.d.ts:416:13 Subsequent variable declarations must have the same type. Variable 'require' must be of type 'NodeRequire', but here has type 'Require'.

but also
ERROR in [at-loader] src/index.tsx:17:28 File 'node_modules/@types/requirejs/index.d.ts' is not a module.

Anyone visiting this after years :) Here is what we observed.

1. We are building a project for browser
2. But also using mocha without testing in browser
3. This required us to install ts-node and amd-loader
4. Unfortunately, installing these deps started resulting in built errors.
