node.js - 在 Ubuntu 上安装 Bower 版本 1.8.2 时出错

Question

我正在尝试安装 Bower 版本 1.8.2
在我的 Ubuntu 16.04 上全局运行

但它显示缺少写入权限/usr/local/bin

我有 Node 4.2.6 和 npm 3.5.2 我收到这个错误:

 ubuntu@ubuntu-Inspiron-3521:~/Desktop/Python-2.7.14$ npm install -g bower

您可以使用 sudo 安装它:

sudo npm i --global bower

但不建议这样做，因此您可以像这样修复 npm 权限:

sudo chown -R $(whoami) $(npm config get prefix)/lib/node_modules

您可以找到gist for the same here.
