MAC node + git + bower 简单安装

一 node 安装

打开https://nodejs.org/en/ nodejs官网 下载安装文件 双击.pkg 文件 自动安装即可

二 安装git

打开 http://code.google.com/p/git-osx-installer/ 下载最新的PGK文件 双击.pkg 文件 自动安装即可。（注：可能遇到 信任问题 可以在 系统偏好设置－>安全性与隐私－>允许从以下位置下载的应用 选择继续安装）

github使用SSH链接，需要设置SSH

1.检查SSH key

cd ~/.ssh

2.备份已有的key，（如果有的话）

mkdir key_backup

mv id_rsa* key_backup

3.生成SSH key

$ ssh-keygen -t rsa -C sunjianping88@126.com

Generating public/private rsa key pair.

Enter file in which to save the key (/Users/sunjianping88/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):             ／／＃＃＃这个地方是设置密码 输入自己要设置的密码即可 也可以不输入

Enter same passphrase again:

Your identification has been saved in yes.

Your public key has been saved in id_rsa.pub.

The key fingerprint is:

xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx sunjianping88@126.com

The key's randomart image is:

+---[RSA 2048]----+

|..+= .=B**+*o    |

|o o . oo+=o.o    |

| . ...  o *..    |

| .oE . o = +     |

|oo... o S        |

|= .  .   .       |

|oo               |

|=o.              |

|B+               |

+----[SHA256]-----+

4.将SSH key添加到GitHub

$ cat ~/.ssh/id_rsa.pub

ssh-rsa AAAAB3NzaC1yc2ExxxzzzzzzQABAAABAQDv7Yb10i+bV5S5sueGVP9NRYYcUKpx+A/IPZS0ZWId469SaIW9ajrGNFSlIwxxxxxxxmhvCGI9nY4c3uD4m3dJvo+EfGduEya4uZS2gPNmZ7osmV6TCdgfTVUqlifK1/rzt0iEyriM8BcIeh+lxb3m/fU+6vuxteqEiHAUArt2dxxxxxxxxxrZxxSNq8He8t+/wSkusCxxxCaoNobxxxxUZHauol7ybqnaNGhW3oTlNnd08RfMv16MtAlKrX5Gvy2jyxchjxXXeL6tQvxxxxxeUyXaLcVSMw+JKLaUHJRG6eBt2rnNvTd35ALx1ObI/qTMxxxxxxxx0jmMhmEVKxshbn sunjianping88@126.com

登录到GitHub页面，personal settings ->SSH and GPG Keys->New SSH key

将生成的key(id_rsa.pub文件，即上面命令cat ~/.ssh/id_rsa.pub获取文件的内容）内容copy到输入框中，点击Add SSH key。

5.测试链接

$ ssh git@github.com

The authenticity of host 'github.com (192.30.252.122)' can't be established.

RSA key fingerprint is SHA256:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added 'github.com,192.30.252.122' (RSA) to the list of known hosts.

Saving password to keychain failed

Identity added: /Users/sunjianping/.ssh/id_rsa ((null))

PTY allocation request failed on channel 0

Hi sunjp748! You've successfully authenticated, but GitHub does not provide shell access.

Connection to github.com closed.

出现上述提示信息说明连接成功（github并不提供shell登陆但已经连接成功）

6.设置个人信息

$ git config --global user.name "your_name"

$ git config --global user.email your_email@xxx.com

三 bower安装

1.输入命令

$ sudo npm install -g bower

/usr/local/bin/bower -> /usr/local/lib/node_modules/bower/bin/bower

bower@1.7.9 /usr/local/lib/node_modules/bower

2.新建.bowerrc文件 设置下载文件的保存目录

（1）可以在项目根目录下新建一个txt文件 然后mv x.txt .bowerrc

（2）修改.bowerrc文件内容为

{
"directory" : "public/javascripts/lib"//要保存下载库文件的目录
}

3.进入项目目录中，输入命令如下 bower init 然后按照提示填写内容即可 遇到选择Y／n的选择Y即可

4.尝试下下载文件

$ bower install jquery --save

bower not-cached    https://github.com/jquery/jquery-dist.git#*

bower resolve       https://github.com/jquery/jquery-dist.git#*

bower checkout      jquery#2.2.4

bower progress      jquery#* Receiving objects:  26% (35/133), 220.00 KiB | 105.00 KiB/s

bower resolved      https://github.com/jquery/jquery-dist.git#2.2.4

bower install       jquery#2.2.4

jquery#2.2.4 public/javascripts/lib/jquery

出现以上内容证明已经部署成功
