jest 在处理 es2015 模块的时候， 如果是 node_modules 里的，会报错，以 lodash-es/cloneDeep 为例:

/node_modules/lodash-es/cloneDeep.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import baseClone from './_baseClone.js';

   ^^^^^^
    SyntaxError: Unexpected token import

      at ScriptTransformer._transformAndBuildScript (node_modules/jest-runtime/build/ScriptTransformer.js:290:17)
      at Object.<anonymous> (src/fetch.ts:46:70)
      at Object.<anonymous> (src/index.ts:6:10)

参照设置(https://facebook.github.io/jest/docs/configuration.html#transformignorepatterns-array-string)，添加

"transformIgnorePatterns": ["<rootDir>/node_modules/(?!lodash-es)/"]

然而并不生效，各位大神知道怎么做么?

具体 repo(lodash 分支): https://github.com/doxiaodong/intercept-fetch/tree/lodash

执行: yarn install, npm test 即可出现
