安装聚合物时npm误差

Question

我试图使用html和javascript测试传感器，就像它显示的这里一样，但是当我尝试安装聚合物时，它是在自述文件中编写的，我得到了以下错误：

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

即使我试图以sudo的身份运行它，我也可以得到以下结果：

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

有一个善良的灵魂可以帮助我吗？

Answer 1

你可以用，

sudo npm install --unsafe-perm -g polymer-cli

不安全-perm标志设置为true，以在运行包时抑制用户标识符/组标识符切换，scripts.The标志显式设置为false，以防止非根用户安装包。

您还可以尝试更改node_modules的所有权，

若要将所有权更改为当前用户为组-

sudo chown -R root: <YOUR_USERNAME>/usr/local/lib/node_modules/

sudo chmod -R 775 /usr/local/lib/node_modules/

也不要使用sudo进行与npm相关的查询。

Answer 2

您有一个典型的npm EACCES许可问题。这与您的用户没有修改npm试图存储全局包的目录的权限有关。这会很烦人的。您应该在这里查看哪种解决方案最适合您：https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
