这是我的代码：
// vim:ft=javascript:
const {Spanner} = require('@google-cloud/spanner');
const spanner = new Spanner({projectId: 'gcp-in-action-317405'});
const instance = spanner.instance('test-instance');
const database = instance.database('test-database');
const employees = database.table('employees');
employees.insert([
{employee_id: 1, name: 'Steve Jobs', start_date: '1976-04-01'},
{employee_id: 2, name: 'Bill Gates', start_date: '1975-04-04'},
{employee_id: 3, name: 'Larry Page', start_date: '1976-04-01'}
]).then((date) => {
console.log('Saved data!', data);
});
代码运行后退出，并出现以下错误：

对于进一步的上下文，这里是gcloud projects list:的输出

显然，我想与"；GCP在行动"；(827217411854(，但谷歌云认为我正在处理"；Qibla Finder"(84555343487(，我已经好几年没有用它开发了。在任何人提出要求之前，我已经确定运行gcloud config set project gcp-in-action-317405。如何将扳手指向正确的方向？
您似乎正在使用应用程序默认凭据(GOOGLE_APPLICATION_CREDENTIALS=/path/to/some.key(对代码进行身份验证。
我怀疑您正在使用的密钥属于qibla-finder-1507320565537所拥有的服务帐户，并且当您的代码进行调用时，正在检查拥有该帐户的项目是否有API(但它没有在其中启用(。
您可能想在gcp-in-action-317405中创建一个新的服务帐户，为其指定合适的Spanner等角色，并使用它验证您的代码。
注意您可以在其他项目中授予现有服务帐户对Spanner的访问权限，但您仍需要在
qibla-finder-1507320565537中启用API
更新：如何创建服务帐户
使用gcloud，您可以创建一个服务帐户，授予它一个合适的角色，创建一个密钥，并使用导出密钥
