How To Reproduce

执行 npm run start 之后控制台中输出了错误信息，src/pages/index.tsx 中参数 foo 为隐式 any 类型，正常情况下应该被报错

internal/modules/cjs/loader.js:968
  throw err;
  ^

Error: Cannot find module 'D:\Code\fork-ts\node_modules\@umijs\deps\compiled\fork-ts-checker-webpack-plugin\TypeScriptReporterRpcService.js'

√ Webpack
  Compiled successfully in 3.14s

RpcIpcMessagePortClosedError: Process 3860 exited with code "1" [null]
Issues checking service aborted - probably out of memory. Check the `memoryLimit` option in the ForkTsCheckerWebpackPlugin configuration.
If increasing the memory doesn't solve the issue, it's most probably a bug in the TypeScript or EsLint.

Context

• Umi Version: 3.4.0-beta6
