Node.js 发生未处理的异常：找不到模块"@角度devkit/build angular“；从「/“ang前端”；。用docker和docker编写

我在运行

docker compose

中的angular应用程序时出现此错误，但奇怪的是，在运行

docker run

时没有出现此错误

docker compose

我对这个问题完全感到困惑。我用

npm update

--save dev

等工具尝试了一切。 这个问题仍然存在

我在AngluarJs/Node开发方面没有太多经验。如果有人能指出我做错了什么，那就太好了

谢谢

我在平均堆栈应用程序中遇到了相同的错误。最后，我终于解决了这个问题

该问题与docker-compose.yml文件中的卷装载有关

version: '3'

services: 
    angular:
        build: angular-client
        container_name: ecommerce-client
        ports:
            - "4200:4200"
        volumes:
            - ./angular-client/:/var/www/app
            - /var/www/app/node_modules/ <-- this should be added

---

注意：docker-compose.yml文件未读取.dockrignore文件。Dockerfile正在使用Dockerfile。

运行节点应用程序时有一种常见模式，将

Node_模块

放入卷中，这会主动阻止Docker更新任何已安装的库（因为卷通常包含无法覆盖的用户数据）。您的

docker compose.yml

文件是否有这样的

，删除它们是否有帮助？如果没有，你能在问题中包括

docker compose.yml

文件吗？@DavidMaze是的，我在docker compose文件中有卷。我将主机应用程序文件夹映射到docker容器中的应用程序文件夹。非常感谢你的指导。这对我帮助很大。我只是忘记了主机没有

npm安装

node\u modules
