转向角应用程序:不存在文件替换中的/app/src/environments/environments.prod.ts路径

Question

我在试着修改一个有角度的应用程序。下面是dockerfile：

FROM node:alpine AS build
ENV NODE_ENV=development

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY *.json ./
COPY *.js ./
COPY src .

RUN npm run build

FROM nginx:alpine

WORKDIR /usr/share/nginx/html

COPY --from=build /app/dist .

下面是angular.json配置：

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "cli": {
    "analytics": false
  },
  "version": 1,

            "styles": [
              "src/styles.scss"
            ],

          }
        }
      }
    }
  },
  "defaultProject": "web"
}

它在第9步抛出以下错误的原因是什么？我试图在互联网上查找这个错误，并找到了一对资源(这和这)，但这些对我没有任何帮助。

Warning: Support was requested for IE 11 in the project's browserslist configuration. IE 11 support is deprecated since Angular v12.
For more information, see https://angular.io/guide/browser-support
An unhandled exception occurred: The /app/src/environments/environment.prod.ts path in file replacements does not exist.
See "/tmp/ng-PPmHPI/angular-errors.log" for further details.
unable to stream build output: The command '/bin/sh -c npm run build' returned a non-zero code: 127. Please fix the Dockerfile and try again..

这个错误似乎是不言自明的，但请注意，我在指定的路径中有该文件。所以这个错误肯定是由于别的原因造成的。

Answer 1

所以我需要反映完全相同的数据结构。而不是

COPY src .

一定是

COPY src ./src

感谢@jrichardsz告诉我一些调试步骤。
