Question

运行yarn docker-build可以正常工作，但是当yarn docker-up或yarn docker-dev被调用RUN yarn时会弹出错误。 Nginx启动正常，但是yarn失败进入Projects目录中的mkdir。

package.json

...
    "docker-build": "docker-compose build",
    "docker-dev": "cross-env NGINX_HOST=localhost NGINX_PORT=3000 PORT=3000 docker-compose -f docker-compose.yml -f docker-compose.dev.yml up --no-deps",
    "docker-up": "cross-env NGINX_HOST=localhost NGINX_PORT=80 PORT=8080 docker-compose -f docker-compose.yml -f docker-compose.prod.yml up --no-deps -d",
    "docker-down": "docker-compose down"
...

Answer 1

我对npm有同样的问题。我使用：

RUN npm config set unsafe-perm true

另一种方法是在安装命令中指定它：

npm install -g --unsafe-perm thePackage

您可以在此处找到其文档：https://docs.npmjs.com/misc/config#unsafe-perm

Answer 2

您可能在docker-compose文件中指定了一个卷，并已将其安装为/project/node_modules，您的用户无权访问本地磁盘上的该目录。

使用this SO answer查找卷映射到的本地目录，并使用以下方式更改所有者：

sudo chown -R yourusername:yourusername /path/to/node_modules

Answer 3

尝试在Dockerfile中运行RUN --mount=type=ssh,id=github_ssh_key pip install private-repo && more commands ...之前设置用户。

yarn

Answer 4

尝试在您的应用程序服务下向您的docker-compose文件添加./node_modules卷。

类似的东西：

services:
  app:
    command: yarn start
    volumes:
      - .:/project
      - ./node_modules:/project/node_modules

Answer 5

我建议像这里建议的那样做 (https://github.com/nodejs/docker-node/issues/1262#issuecomment-677577653)。所以从这里更改以下几行

# Copy required stuff
COPY . .

# Give owner rights to the current user
RUN chown -Rh $user:$user /project

到这里

# Copy required stuff
COPY --chown $user:$user . .

或者作为替代更改您的 WORKDIR (https://github.com/nodejs/docker-node/issues/740#issuecomment-458545074)：

WORKDIR /home/node/project

Docker-“错误：EACCES：权限被拒绝，mkdir'/project/node_modules/.cache/@babel'”
