下载地址
- 打开iTerm,输入
mkdir ~/bin
,在当前用户根目录下创建一个bin
目录; - 把class-dump给拷贝到这个目录里,
mv /path/to/class-dump ~/bin
并赋予其可执行权限: chmod +x ~/bin/class-dump
- 打开
~/.bash_profile
文件:vi ~/.bash_profile
, 在文件最上方加一行:export PATH=$HOME/bin/:$PATH
,然后保存并退出(在英文输入法中依次按下esc和:
(shift +;
,即冒号),然后输入wq
,回车即可); - 在iTerm中执行
source ~/.bash_profile
