Docker容器无法启动NestJs应用

Question

我有NestJs API服务，当使用“ npm run dev”命令运行时，它运行得很好。但是当我进行docker化时，它无法运行该应用程序。我也在容器中尝试了节点版本9,10和12。但是使用run dev命令可以在我的计算机上的节点版本9上顺利运行。我正在使用docker run -it -p 9000:3001 dev-service运行容器。错误如下。

 [email protected] start /app
> node index.js "prod"

Docker文件：

ROM node:9
WORKDIR /app
COPY package.json /app
COPY ormconfig.json /app
RUN npm install
COPY . /app
COPY ormconfig.json /dist/

CMD ["npm", "start", "prod" ]

我通过安装粉笔库解决了该问题。发生这种情况的原因是承包商正在寻找粉笔，并且未安装在节点模块中。但这仅在我通过docker运行时才引起。无论如何，在我将依赖关系放入粉笔之后，它就可以工作了。
