Docker：EACCES：权限被拒绝，mkdir '/app/node_modules/.cache'

Question

我在尝试在 React 应用程序中构建 docker 容器时遇到权限错误。
我试图利用社区的答案，但没有帮助。
关注相关discussion我试过了：

• 我得到当前用户：id -un
• 试过这个：sudo chown -R myUser:myUser /usr/local/lib/node_modules
• 这也抛出了同样的错误：sudo chown -R ownerName: /usr/local/lib/node_modules
• 与此相同：sudo chown -R $USER /usr/local/lib/node_modules
• 添加用户没有帮助：sudo chown -R $USER /app/node_modules
• 试图授予安装此权限：sudo npm install -g --unsafe-perm=true --allow-root
• 另一个尝试是删除 node_modules 并安装指定 sudo: sudo npm install

将此添加到docker-compose 文件，也没有帮助：

environment:
      - CHOKIDAR_USEPOLLING=true

我正在尝试使用以下命令进行构建：docker-compose up --build

Dockerfile.dev 文件

FROM node:alpine

WORKDIR '/app'

COPY package.json .
RUN npm install

COPY . .

CMD ["npm", "run", "start"]

docker-compose.yml 文件

version: "3"
services:
  web:
    stdin_open: true
    environment:
      - CHOKIDAR_USEPOLLING=true
    build:
      context: .
      dockerfile: Dockerfile.dev
    ports:
      - "4000:4000"
    volumes:
      - /app/node_modules
      - .:/app

错误

任何帮助将不胜感激

Answer 1

试试这个 Docker - EACCES: permission denied, mkdir '/app/node_modules/.cache'

这对我有用

RUN chown -R node:node /app/node_modules

或 sh 进入 docker 容器并运行

chown -R node:node /app/node_modules
