Error: Call retries were exceeded

angular8 编译报错 Error: Call retries were exceeded at ChildProcessWorker.initialize，具体如下：
Angular CLI版本: 8.3.21

[error] Error: Call retries were exceeded
    at ChildProcessWorker.initialize (/data/html/boboJavaBlog/toolsWeb/node_modules/jest-worker/build/workers/ChildProcessWorker.js:193:21)
    at ChildProcessWorker.onExit (/data/html/boboJavaBlog/toolsWeb/node_modules/jest-worker/build/workers/ChildProcessWorker.js:263:12)
    at ChildProcess.emit (events.js:189:13)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:248:12)

解决办法

tsconfig.json中的target从es2015改为es5
