Angular 8 docker容器即使安装也找不到模块

Question

我正在构建一个 Angular 8 SPA。我有一个使用 Docker Compose 配置构建和运行的 Dockerfile。

配置已经工作了几个星期，但今天，它突然停止工作。我没有对以前的工作做任何改变。

由于模块错误，Angular 应用程序不再编译，并且由于此问题，所有开发现在都被阻止。

error TS2307: Cannot find module 'ngx-cookie-service'.

我试过：

• 卸载并重新安装 ngx-cookie-service 模块

• 删除并重新创建 node_modules 和 package-lock.json

• 运行 npm cache clean

• 运行 docker system prune 并重建镜像

• 手动更改 ngx-cookie-service 的版本

• 确认 node_modules/ngx-cookie-service 目录存在

题：

我还可以采取哪些其他步骤来解决问题？

在构建期间复制 Dockerfile 中的构建时，无需在 docker-compose 中挂载主机目录。

# Copy code
COPY ./angular /home/node/app

这足以运行应用程序，因此您可以从 Docker-compose.yml 中删除这些。

      - './client/angular/:/home/node/app'
      - '/home/node/app/node_modules'

如果要运行表单容器，请使用容器安装构建目录。

      - './client/angular/:/home/node/app'

此外，您可以调试包。安装后列出包。

RUN npm install
RUN npm list

或者，如果问题仍然存在，则尝试将该包作为全局包。

RUN npm i ngx-cookie-service -g

有时，由于不同的二进制文件，主机绑定模块无法像我们预期的那样工作，因此最好在运行时在 docker-compose 中安装。

在 docker-compose 文件中添加这个

command: sh -c "
  npm i &&
  ng serve --host 0.0.0.0"
