mac osx 下 homebrew安装

由于很多开源的东西，苹果没有安装源，可以使用homebrew来管理安装，所以在osx下安装好homebrew还是很方便的。记录下。

1. 查看版本

ruby -versionruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]-e:1:in `<main>': undefined local variable or method `rsion' for main:Object (NameError)

2.安装homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

如果提示出错了Error: /usr/local/Cellar is not writable. You should change the
ownership and permissions of /usr/local/Cellar back to your
user account:
输入下面的命令行

sudo chown -R $(whoami) /usr/local/Cellar

然后继续安装输入上面的安装指令

3.检测是否安装成功

brew

如果安装成功了，会返回如下命令
Example usage:
brew search [TEXT|/REGEX/]
brew (info|home|options) [FORMULA…]
brew install FORMULA…
brew update
brew upgrade [FORMULA…]
brew uninstall FORMULA…
brew list [FORMULA…]

Troubleshooting:
brew config
brew doctor
brew install -vd FORMULA

Developers:
brew create [URL [–no-fetch]]
brew edit [FORMULA…]
https://docs.brew.sh/Formula-Cookbook.html

Further help:
man brew
brew help [COMMAND]
brew home

4.使用brew来安装node

brew install node

如果提示
Error: The brew link step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink .
/usr/local/opt is not writable.

更新权限，然后再去链接一下

sudo chown -R $(whoami) /usr/localbrew link node

安装ios-deploy

npm install -g ios-deploy

如果安装出错了
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.58.dylib
Referenced from: /usr/local/bin/node
Reason: image not found
Abort trap: 6
安装一下 icu4c, 然后link一下

brew install icu4cbrew link icu4c
