两天前，我的 node.js 构建在 gitlab-ci 服务器上停止工作。我真的不明白为什么。更多信息：
- ci 构建停止工作时
package.json文件未更改 - 即使是几天前还可以的较旧的ci-build，当我重新启动它们时也不再工作了
- 该构建仍然适用于我的 Windows 开发机器（即使在删除 node_modules 并重新安装之后）
以下是错误日志的摘录：

似乎无法下载 grpc 二进制文件，作为后备系统，系统尝试从源代码构建包，但也失败了。grpc 需要firebase-admin：
npm ls grpc
`-- firebase-admin@6.1.0
`-- @google-cloud/firestore@0.18.0
`-- google-gax@0.20.0
`-- grpc@1.16.0
知道为什么会发生这种情况或解决方法的想法吗？
即版本配置为"firebase-admin": "^6.1.0",我的package.json，所以不应该有任何重大变化，对吧？
