Question

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

该配置已经运行了几周，但是今天，它突然停止了工作。我没有对以前的工作进行任何更改。

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

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

我尝试过：

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缓存清理
运行docker系统修剪并重新构建映像
手动更改ngx-cookie-service的版本
确认存在node_modules / ngx-cookie-service目录

问题：

我还可以采取什么其他步骤来解决此问题？

Dockerfile

### Local development only ###

FROM node:12.8-alpine

# Install bash
RUN apk add --no-cache bash

# Create working directory
RUN mkdir -p /home/node/app

# Set working directory
WORKDIR /home/node/app

# Add `/home/node/app/node_modules/.bin` to $PATH
ENV PATH /home/node/app/node_modules/.bin:$PATH

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

# Expose ports
EXPOSE 4201:4201

RUN npm install

# Start Angular
CMD ng serve --host 0.0.0.0

docker-compose.yml

version: '3.5'

services:

  client:
    build:
      context: ./client
      dockerfile: Dockerfile
    volumes:
      - './client/angular/:/home/node/app'
      - '/home/node/app/node_modules'
    ports:
      - '4201:4201'

在构建期间将构建复制到Dockerfile中时，则无需将主机目录挂载到docker-compose中。

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

这足以运行该应用程序，因此您可以将它们从Docker-compose中删除。

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

如果要运行表单容器，请使用容器挂载构建目录。

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

此外，您可以调试软件包。安装后，列出软件包。

RUN npm install
RUN npm list

或者，如果仍然存在问题，则尝试将该程序包作为全局程序包。

RUN npm i ngx-cookie-service -g

有时由于不同的二进制文件，主机绑定模块无法正常工作，因此最好在运行时将其安装在docker-compose中。

将此添加到docker-compose文件中

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

Answer 2

在完成 @Alli 接受的答案后，我遇到了错误 Cannot find module '@angular-devkit/build-angular/package.json'，我通过告诉我的 Dockerfile 像这样安装它来修复它：

RUN npm install -g @angular/cli
RUN npm install --save-dev @angular-devkit/build-angular
RUN npm install

对于那些出于开发目的而 Dockerizing Angular 的人，不要删除卷定义，这样代码中的任何更改都会反映在容器中。

不要删除开发环境的卷定义

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

Angular 8 Docker容器即使已安装也无法找到模块
