ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
// 期間需要輸入密碼
（安裝目錄在 cd /usr/local/Cellar/ 下）
2.安裝chisel

==> Caveats
Add the following line to ~/.lldbinit to load chisel when Xcode launches:
command script import /usr/local/opt/chisel/libexec/fblldb.py
==> Summary

按照安裝提示：
*Add the following line to ~/.lldbinit to load chisel when Xcode launches:
command script import /usr/local/opt/chisel/libexec/fblldb.py
在~/.lldbinit 文件中添加一行命令能颁，如果沒有l(wèi)ldbinit文件則在該目錄( ~/)下新建一個''.lldbinit''文件并在該文件中增加上述內容
:~ $ touch .lldbinit
:~ $ vi .lldbinit
/*
#.lldbinit 文件
command script import /usr/local/opt/chisel/libexec/fblldb.py
