我无法从gitlab ci / cd连接到mlab（mongodb在线服务），但可以轻松地从本地连接到mlab。 两种情况下我都使用相同的配置，但是为什么本地和gitlab不同？我在这里很困惑
此外，这是我第一次尝试集成ci / cd，因此我陷入各种愚蠢的问题是很正常的事，但是我被困了两天而又不知道是什么问题。
我尝试使用此https://github.com/Automattic/mongoose/issues/6332以及此链接-> https://github.com/Automattic/mongoose/issues/4587
的解决方案但是问题没有解决。
在这里我记下了gitlab yml文件，请看一下，如果我在这里错过了任何内容。
cache:
paths:
- node_modules/
- src/client/node_modules/
stages:
- deploy
install_dependencies:
stage: deploy
script:
- npm install
- npm run installClientDependencies
- npm run devRemoteServer
- echo $NODE_ENV
only:
- master
这是gitlab作业日志所说的（错误）
