node.js - npm 安装 bower 时出错。

问题描述

问 题

以下是命令和报错：

首先我直接按照官方文档进行安装：
[glenn@centos7 imooc]$ npm install bower -g
npm ERR! tar.unpack untar error /home/glenn/.npm/bower/1.7.9/package.tgz
npm ERR! Linux 3.10.0-327.22.2.el7.x86_64

嗯 根据提示可能是权限问题，所以
[glenn@centos7 imooc]$ sudo npm install bower -g
[sudo] password for glenn:
sudo: npm: command not found
然而不行，我看了下路径
[glenn@centos7 imooc]$ whereis npm
npm: /usr/local/bin/npm

然后我 google 了一下，似乎没人遇到这个问题。

解决方案

试试sudo /usr/local/bin/npm install bower -g
