[npm尝试安装聚合物时出现错误

我正在尝试使用html和javascript来测试传感器，如图here所示，但是当我尝试安装polymer时，因为它是在自述文件中编写的，因此出现此错误：

kupu@kupu:~/Dropbox/IOT/generic-sensor-demos/sensor-info$ npm install -g polymer-cli

即使我尝试以sudo的身份运行，我也会得到这个：

kupu@kupu:~/Dropbox/IOT/generic-sensor-demos/sensor-info$ sudo npm install -g polymer-cli

那里有一个可以帮助我的好灵魂吗？

您遇到了典型的npm EACCES权限问题。这与您的用户无权修改npm试图存储全局软件包的目录有关。可能会很烦人。您应该在此处查看哪种解决方案最适合您：https://docs.npmjs/resolving-eacces-permissions-errors-when-installing-packages-globally
