node.js - npm链接包名必须有name字段才能链接

Question

嗨，我正在尝试创建一个 docker 镜像。 下面是我的 docker 文件的一部分，它导致了问题。我认为问题是由于 nodejs 包造成的。

当前的软链接(soft link)是: ls -la“/usr/bin/npm” lrwxrwxrwx 1 root root 3月2日25日01:50/usr/bin/npm ->/usr/lib/node_modules/npm

安装由非 root 用户完成

Docker 文件

 #Install node js and npm
    RUN curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
    RUN apt-get -y install nodejs
    RUN npm install -g bower gulp
    RUN npm install -g node-gyp@latest --save
    RUN npm init -y
    RUN npm install -g n
    RUN npm install zmq --save
    RUN ldconfig
    RUN npm config set prefix ~/npm

    #RUN npm install -g stf t
    #RUN npm install
    #RUN rm -rf /usr/bin/npm
    #RUN ln -s /usr/lib/node_modules/npm/ /usr/bin/npm
    RUN npm link   

下面是 docker 构建输出:

问题是生成的package.json没有name属性集"name": "", 。

如 npm-link 中所述:

Note that package-name is taken from package.json, not from directory name

原因name package.json 中为空是你正在运行 npm init在根/容器的。 您必须创建一个目录并运行 npm init在那里。

WORKDIR /app
RUN npm init -y
