Reactjs “本地npm依赖性”；不包含package.json文件；在docker构建中，但在npm启动时运行良好

我有一个npm模块，我正在本地工作，它是客户端应用程序中的一个依赖项

目录结构基本如下：

/app
  /client
    /src
      App.js
    package.json
    Dockerfile.dev
  /shared
    /contexts
      package.json
      test.js
    /hooks

{
  "name": "web",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "contexts": "file:../shared/contexts",
    "react": "^16.10.2",
    "react-dom": "^16.10.2",
    "react-scripts": "3.2.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

FROM node:alpine
WORKDIR '/app'
COPY ./shared /shared
COPY ./web /app
RUN npm install
CMD ["npm", "run", "start"]

我的

package.json

如下所示：

/app
  /client
    /src
      App.js
    package.json
    Dockerfile.dev
  /shared
    /contexts
      package.json
      test.js
    /hooks

{
  "name": "web",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "contexts": "file:../shared/contexts",
    "react": "^16.10.2",
    "react-dom": "^16.10.2",
    "react-scripts": "3.2.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

FROM node:alpine
WORKDIR '/app'
COPY ./shared /shared
COPY ./web /app
RUN npm install
CMD ["npm", "run", "start"]

将以下内容导入到

客户端/src/App.js

：

import { testImport } from 'contexts/test';

运行

npm start

时按预期工作

我遇到的问题是跑步：

docker build -t sockpuppet/testapp -f Dockerfile.dev .

它失败了，我得到一个错误：

npm ERR! Could not install from "../shared/contexts" as it does not contain a package.json file.

这是Dockerfile.dev

FROM node:alpine
WORKDIR '/app'
COPY ./package.json ./
RUN npm install
COPY . .
CMD ["npm", "run", "start"]

我应该如何处理本地npm依赖关系

此外，向映像中的

/shared

添加类似以下内容会生成

复制失败：生成上下文之外的禁止路径：../shared/contexts（）

错误：

COPY ../shared ./

---

好的，这样行。我将我的

Dockerfile.dev

更改为以下内容：

/app
  /client
    /src
      App.js
    package.json
    Dockerfile.dev
  /shared
    /contexts
      package.json
      test.js
    /hooks

{
  "name": "web",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "contexts": "file:../shared/contexts",
    "react": "^16.10.2",
    "react-dom": "^16.10.2",
    "react-scripts": "3.2.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

FROM node:alpine
WORKDIR '/app'
COPY ./shared /shared
COPY ./web /app
RUN npm install
CMD ["npm", "run", "start"]

从基本项目目录（其中

/shared

和

/web

驻留），我运行：

你在层次结构中放置Dockerfile的位置？你能显示你的Dockerfile吗？看起来像上下文问题

。/shared/contexts“

这是在Dockerfile的上下文之外，你没有在Dockerfile中复制，那么你是如何得到这个错误的？我唯一能想到的是不要让它成为本地npm依赖项，但这样做会失去好处<代码>复制../shared./会生成

外部生成上下文

错误。
