我正在尝试使用npm在Mac OS Yosemite上安装bower，但它失败并显示以下消息

我已经使用npm
成功安装了其他软件包 /usr/local/lib
├── cordova@5.1.1
├── gulp@3.9.0
├── ionic@1.6.1
├── npm@2.12.1
└── yo@1.4.7
但是当我尝试安装凉亭时，我得到了上述错误。我不在任何防火墙后面，我的npm配置是
; cli configs
user-agent = "npm/2.12.1 node/v0.12.7 darwin x64"
; userconfig /Users/larris/.npmrc
registry = "http://registry.npmjs.org/"
strict-ssl = false
; builtin config undefined
prefix = "/usr/local"
; node bin location = /usr/local/bin/node
; cwd = /Users/larris
; HOME = /Users/larris
; 'npm config ls -l' to show all defaults.
