docker - 即使在 docker 构建镜像时安装了 angular-cli ng 命令，也未找到该命令

Question

我尝试为一个以 angular-cli 作为 Controller 的应用程序构建一个图像。在构建时使用 ng build --prod命令，docker builder崩溃。

我尝试在全局或本地文件夹上实现 angular-cli，但每次 ng调用命令时，构建控制台表示它无法在不是 angular-cli 应用程序的文件夹上构建。

问题是 docker 构建进程运行 ng build在右侧文件夹中。这是我的 docker 文件。

错误消息:The command '/bin/sh -c ng build --prod' returned a non-zero code: 127 其他错误消息:/bin/sh: 1: ng: not found

当前目录在每个 Dockerfile 层中设置为 WORKDIR，因此它会丢弃您 cd 的任何内容。所以改变一下

RUN cd /opt/ && ls -l
RUN ng build --prod

致:

WORKDIR /opt/
RUN ng build --prod

或者:

RUN cd /opt/ && ng build --prod

此外，请确保 npm 目录位于您的“PATH”变量中。
