当运行-d时，NestJ后端在-d初始化过程中失败

Question

我有一个单独的应用程序后端(NestJ)和前端(AngularJs)。

在本地运行后端时(嵌套启动)，然后获得成功，如下所示：

但是，当使用docker时-组合-d，然后出现以下错误：

在这里输入图像描述

使用的NestJ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，所有这些都是在向我的一个事件网关添加了一些命名空间之后开始的。从错误消息看，它似乎找不到从shared_utils_1.导出的实用程序函数。经过简短的调查，结果证明这是作为"nestjs/common"包的一部分输出的。因此，我查看了正在作为构建过程的一部分复制到坞容器中的package.json，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，一切似乎都正常了。
