煩惱，當我使用自制

Question

我想安裝的git在我的Mac（OS X 10.10.3）。我寫：沖泡安裝的git

但報道：

sh: line 1: 1549 Abort trap: 6   /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk/-find clang 2> /dev/null 
clang: error: unable to find utility "clang", not a developer tool or in PATH 
sh: line 1: 1552 Abort trap: 6   /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk/-find otool 2> /dev/null 
otool: error: unable to find utility "otool", not a developer tool or in PATH 
Error: Failure while executing: /usr/bin/otool -L /usr/bin/install_name_tool 

然後我寫沖泡醫生。它報道：

Warning: /usr/local/include isn't writable. 

This can happen if you "sudo make install" software that isn't managed by 
by Homebrew. If a formula tries to write a file to this directory, the 
install will fail during the link step. 

You should probably `chown` /usr/local/include 

Warning: /usr/local/lib isn't writable. 

This can happen if you "sudo make install" software that isn't managed by 
by Homebrew. If a formula tries to write a file to this directory, the 
install will fail during the link step. 

You should probably `chown` /usr/local/lib 
sh: line 1: 1318 Abort trap: 6   /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk/-find otool 2> /dev/null 
otool: error: unable to find utility "otool", not a developer tool or in PATH 
Error: Failure while executing: /usr/bin/otool -L /usr/bin/install_name_tool 

話，我chown將此lib和與包括「命令CHOWN 755」「包括須藤CHOWN 755 LIB」 第一和第二報警被刪除，但在第三個仍然存在。

而我更困惑的是，在我的發現者：/ usr/local /「include」和「lib」應該是文件夾，但成爲文件。 我怎樣才能解決錯誤「找不到otool」並安裝git與brew和

爲什麼我的lib和包含文件夾成爲文件？...感謝您的幫助！

Answer 1

首先。也許你應該在安裝之前更新自制軟件：

brew update 

二。也許這個指令有幫助（取自Ask Different）。至少它當您解決問題是非常有用的：

 brew install git 
     $ git --version 
      git version 1.7.12.4 (Apple Git-37) 
     $ which git 
      /usr/bin/git 
     **// doh! osx's pre-installed git trumps the brew one, so:** 
     $ sudo mv /usr/bin/git /usr/bin/git-apple 
     $ which git 
      /usr/local/bin/git 
     $ git --version 
      git version 1.8.2 
     // ok cool. 

Answer 2

的問題是，Xcode是無法找到自己的命令行工具出於某種原因：

sh: line 1: 1549 Abort trap: 6  /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk/-find clang 2> /dev/null 
clang: error: unable to find utility "clang", not a developer tool or in PATH 

在終端退房xcode-select --print-path。

如果是/Applications/Xcode.app/Contents/Developer則運行sudo xcode-select --switch /Library/Developer/CommandLineTools將xcode-select設置爲非Xcode命令行工具。

如果您沒有/Library/Developer/CommandLineTools目錄，您可以通過https://developer.apple.com/downloads/獲取您當前的Xcode版本。
