jest-haste-map：观看错误抱怨它无法在 jest-haste-map node_modules 文件夹中找到文件

Question

我刚刚升级到 RN 0.56.0 并且正在使用 jest 版本：22.4.3（更新 jest 版本没有帮助）当我尝试运行我的测试套件时，我在终端中收到以下错误：

jest-haste-map: watch error: Error: ENOENT: no such file or directory, 
open '/Users/mobilepractice/builds/0bcf5ed0/0/cx-mobile/posting- 
plus/PostingPlus/node_modules/jest-haste-map/build/worker.js' at Error 
(native) at Object.fs.openSync (fs.js:640:18) at Object.fs.readFileSync 
(fs.js:508:33) at Module._extensions..js (module.js:578:20) at 
Object.require.extensions.(anonymous function) [as .js]

Function.Module._load (module.js:438:3) at Module.require 
(module.js:497:17) at require (internal/module.js:20:19)

还有这个错误：

/Users/mobilepractice/builds/0bcf5ed0/0/cx-mobile/posting- 
plus/PostingPlus/node_modules/react-native/jest/hasteImpl.js:50 ) /*: 
string | void */ { ^ SyntaxError: Unexpected token ) at

我可以在我的 node_modules 文件夹中看到 worker.js 文件，这就是 ENOENT 错误令人困惑的原因。

一个解决方案是确保安装了节点 8 或更高版本。此错误发生在节点 6.9.1.
