CircleCI 中的 Mocha 测试显示“Workerpool Worker 意外终止”

Question

我使用 Yarn 和 Mocha 运行 TypeScript 测试，它们在本地运行良好。然而，当我通过 CircleCI 部署时，我得到了这个：

1) Uncaught error outside test suite:
   Uncaught Workerpool Worker terminated Unexpectedly
  exitCode: `null`
  signalCode: `SIGKILL`
  workerpool.script: `/home/circleci/my-project/node_modules/mocha/lib/nodejs/worker.js`
  spawnArgs: `/usr/local/bin/node,--inspect,--inspect=43215,/home/circleci/my-project/node_modules/mocha/lib/nodejs/worker.js`
  spawnfile: `/usr/local/bin/node`
  stdout: `null`
  stderr: `null`

Error: Workerpool Worker terminated Unexpectedly
    exitCode: `null`
    signalCode: `SIGKILL`
    spawnfile: `/usr/local/bin/node`
    stdout: `null`
    stderr: `null`
  
    at ChildProcess.<anonymous> (node_modules/workerpool/src/WorkerHandler.js:294:13)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:282:12)

这是我的 CircleCI 配置。我编辑了一些特定于我的项目的字段，并删除了一些在这里没有意义的部分，因为它们用于我当前无法运行的作业，因为它们稍后会在过程中运行。

我已经xdescribe完成了所有测试，但这种情况仍然发生。想法表示赞赏。

更新：我的run.ts文件中有这一行：

const tests = child_process.spawn(
    "APP_ENV=test NODE_ENV=test ssm-env --with-decryption node_modules/mocha/bin/mocha --inspect -r ts-node/register -r tsconfig-paths/register --recursive 'test/**/*.spec.ts' --parallel",
    { stdio: "inherit", cwd: "./", shell: true }
);

我删除了它--parallel，现在一切都很好。仍然对核心问题感到困惑，但至少这是一个解决方法。

Answer 1

我曾经也有过一样的问题。

实际问题是内存不足。

我分配了更多的内存。我的问题解决了。
