Xcode8 安装 XVim，求助

开发环境： Xcode8.2

OS X 10.11.5

折腾了一下午，各种命令行试过， Google 搜了一圈，都尝试过，无解。来 V 站求助。

我参照 XVim Github 上面的教程做的 https://github.com/XVimProject/XVim/blob/master/INSTALL_Xcode8.md

执行到签名这一步的时候死活执行不过去，报错

$ sudo codesign -f -s XcodeSigner /Applications/Xcode.app    (Replace the Xcode path if it is different.)

codesign_allocate: file not in an order that can be processed (link edit information does not fill the __LINKEDIT segment): /Applications/Xcode_8.2.app/Contents/MacOS/Xcode
/Applications/Xcode_8.2.app/: the codesign_allocate helper tool cannot be found or used

Google 上面搜索的一圈，有说尝试找一下 codesign_allocate 的位置，我也找了，如下

locate codesign_allocate
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/share/man/man1/codesign_allocate.1
/Library/Developer/CommandLineTools/usr/bin/codesign_allocate
/Library/Developer/CommandLineTools/usr/share/man/man1/codesign_allocate.1
/usr/bin/codesign_allocate

也把这些路径加到$PATH里面了，都挨个试了，还是提示『找不到 codesign_allocate helper 』

所以想请问一下 V 站用 XVim 的大神，你们都是怎么安装 XVim 的，

iOS 开发小白，都是照葫芦画瓢，有不懂的地方，还请各位请喷，感谢回复！
