在docker image上进行npm global安装时没有访问权限错误

我正在尝试 的firebase-tools和angular-cli 构建一个

。我正在为两个版本的节点构建相同的映像：6.x（LTS硼）和v8.x（最新高山）。在本地，两个映像都可以正常构建，但是当我尝试在docker

hub中构建时，只有v6.x可以成功构建。使用v8.x时，它会陷入 的

。我已经在使用root用户（USER root），因为如果没有此设置（或使用USER节点），则两个图像均无法构建。

这是我的Dockerfile：

FROM node:latest
USER root
RUN npm install --quiet --no-progress -g @angular/cli@latest firebase-tools
RUN npm cache clean --force

这是输出：

回答：

问题是因为当NPM以nobody用户身份运行全局安装的模块脚本时，这是有意义的，但是NPM的最新版本开始将节点模块的文件权限设置为root。结果，不再允许模块脚本在其模块中创建文件和目录。

有关某些参考，请参见NPM问题＃3849中的讨论。

在docker环境中有意义的一个简单变通方法是，将NPM默认全局用户设置为root，如下所示：

npm -g config set user root

之后，您就不会再有EACCES错误了。
