Question

我正在尝试使用html和javascript测试传感器，如图所示here，但是当我尝试安装 polymer 时（如自述文件中所述），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 的身份运行它，我也会得到：

kupu@kupu:~/Dropbox/IOT/generic-sensor-demos/sensor-info$ sudo npm install -g polymer-cli
/usr/local/bin/polymer -> /usr/local/lib/node_modules/polymer-cli/bin/polymer.js

那里有可以帮助我的好灵魂吗？

Answer 1

您遇到一个典型的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

Answer 2

您可以使用

对其进行修复

node_modules

Unsafe-perm标志设置为true以禁止在运行软件包脚本时切换用户标识符/组标识符。该标志显式设置为false以防止非root用户安装软件包。

您还可以尝试更改sudo chown -R root: <YOUR_USERNAME>/usr/local/lib/node_modules/ sudo chmod -R 775 /usr/local/lib/node_modules/的所有权，

要将所有权更改为当前用户作为组-

sudo

绝不要将dataList用于npm相关查询。
