typeerror（屈服* ...是不可能的）

Question

我一直在尝试在 React-Node/Express 项目中实现 Pact。在提供程序测试中，我遇到了一个奇怪的错误，我无法在网上找到解释。我的提供者交互全部通过，但在输出结束时我收到以下错误，这使得测试套件以失败结束，尽管所有测试都通过了

TypeError: yield* (intermediate value)(intermediate value)(intermediate value)(intermediate value) is not iterable

这是提供者测试文件，我在 Docker 中运行，以便我可以针对 Postgres 测试数据库运行测试

    const output = await new Verifier(opts).verifyProvider();
    console.log(output);
  });
});

我尝试将代码的各个部分包装在 try/catch 块中以定位问题，但没有成功。我还调整了我的node_modules中的代码，以便更好地查看

@babel/core/lib/config/files/configuration.js中的loadOneConfig

function* loadOneConfig(names, dirname, envName, caller, previousConfig = null) {
  const configs = yield* _gensync().all(names.map(filename => readConfig(_path().join(dirname, filename), envName, caller)));
  const config = configs.reduce((previousConfig, config) => {
    if (config && previousConfig) {
      throw new Error(`Multiple configuration files found. Please remove one:\n` + ` - ${_path().basename(previousConfig.filepath)}\n` + ` - ${config.filepath}\n` + `from ${dirname}`);
    }

    return config || previousConfig;
  }, previousConfig);

  if (config) {
    debug("Found configuration %o from %o.", config.filepath, dirname);
  }

  return config;
}

问题当我将代码移动到console.log时，我收到了新的错误_gensync().all 不是一个函数，并且 console.logging _gensync() 返回一个空对象。

我尝试将我的babel升级到最新版本，但似乎没有任何效果。
