我正在尝试构建 Angular 图像，但出现此错误：

这是我的 DockerFile：

FROM node:14.17.6 as node
WORKDIR /app
COPY . .
RUN npm install
RUN npm run build --prod
#stage 2
FROM nginx:alpine
COPY --from=node /app/dist/Angular /usr/share/nginx/html

我正在使用适用于 Windows 的 Docker Desktop 4.4.4

PS：我已经尝试增加 docker 引擎的内存并尝试了几个版本的节点，但我遇到了同样的问题。

应用程序可以在我的机器上正常运行，但只有 Docker 镜像无法构建。

有人可以帮忙吗？

【问题讨论】：

你能分享你的 package.json 吗？
“我已经尝试增加 docker 引擎的内存” 为什么？
@jeremy-denis 我用 package.json 更新了帖子
您使用的是 Windows 吗？这是否解决了您的问题：github.com/facebook/create-react-app/issues/9077?

【解决方案1】：

通过在 DockerFile 中添加这一行来解决问题：

RUN npm i -g @angular/cli

似乎是在启动 e2e 测试并且需要 Angular CLI 时出现问题

DockefFile 变为：

#stage 1
FROM node:14.17.6 as node
WORKDIR /app
COPY . .
RUN npm i -g @angular/cli
RUN npm install
RUN npm run build --prod
#stage 2
FROM nginx:alpine
COPY --from=node /app/dist/Angular /usr/share/nginx/html
