Run `brew help` to get started

终端输入：brew install chisel
zqldeMacBook-Pro:~ zql$ brew install chisel ==> Downloading https://github.com/facebook/chisel/archive/1.4.0.tar.gz ==> Downloading from https://codeload.github.com/facebook/chisel/tar.gz/1.4.0 ######################################################################## 100.0% ==> Caveats Add the following line to ~/.lldbinit to load chisel when Xcode launches: command script import /usr/local/opt/chisel/libexec/fblldb.py ==> Summary 🍺 /usr/local/Cellar/chisel/1.4.0: 22 files, 109.5K, built in 7 seconds zqldeMacBook-Pro:~ zql$ 从终端中可以看Caveats下面的那两行，意思是把第二行的文字command script import /usr/local/opt/chisel/libexec/fblldb.py添加到.lldbinit文件中，这时执行命令echo command script import /usr/local/opt/chisel/libexec/fblldb.py >> ~/.lldbinit（粗体文字替换为你终端Caveats下面的第二行文字）可免去你去找.lldbinit文件，或者.lldbinit文件不出现的烦恼啊。到此步不出意外已经安装成功。
如图所示
