我有一个单独的应用程序后端(NestJs)和前端(AngularJs)。
在本地运行后端(嵌套启动)，然后获得如下成功:
[Nest] 51995 - 21/09/2021, 11:17:00 pm [NestFactory] Starting Nest application...

但是当使用docker-compose up -d时，出现以下错误:

使用的NestJs版本:
"@nestjs/common": "^7.0.0",
"@nestjs/core": "^7.0.0",
"@nestjs/jwt": "^7.0.0",
"@nestjs/passport": "^7.0.0",
"@nestjs/platform-express": "^7.0.0",
"@nestjs/platform-socket.io": "^7.3.2",
"@nestjs/serve-static": "^2.1.3",
"@nestjs/typeorm": "^7.1.0",
"@nestjs/websockets": "^7.3.2",
"@types/socket.io": "^2.1.8",
我也面临着同样的问题。实际上，这一切都是在向我的一个事件网关添加一些名称空间之后开始的。从错误消息来看，似乎无法从shared_utils_1中找到一些导出的实用程序函数。． 经过简短的调查，发现这是作为"nestjs/common">的一部分导出的。包中。所以我看了看包装。在构建过程中复制到docker容器的一部分，并注意到该特定包的版本(7.0.9)与我在本地构建应用程序时使用的版本(8.0.0)不同。
我更新了版本(8.0.0)，重新构建了应用程序，从那以后一切似乎都在工作。
