使用svn命令svn commit -m ""出現(xiàn)問題無法使用svn時重新安裝svn過程中碰到的問題記錄一下（沒有問題的忽略）

一 、iTerm中輸入brew install svn? 出現(xiàn)Updating Homebrew 并且一直卡著，這時候替換brew源

cd "$(brew --repo)"

git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

#替換homebrew-core.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"

git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

//后續(xù)如果要還原

#重置brew.git

cd "$(brew --repo)"

git remote set-url origin https://github.com/Homebrew/brew.git

#重置homebrew-core.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"

git remote set-url origin https://github.com/Homebrew/homebrew-core.git

二、替換brew源之后再輸入brew update 一直卡著 輸入brew install svn 出現(xiàn)錯誤Error: subversion: Unsupported special dependency :python

輸入vi /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/subversion.rb?

depends_on :python => :optional

修改 :python 為 "python" 保存退出

再輸入brew install svn 出現(xiàn)錯誤Error: subversion: Unsupported special dependency :perl

輸入vi /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/subversion.rb?

depends_on :perl => :optional

修改 :perl 為 "perl" 保存退出

然后再輸入brew install svn 就可以正常安裝svn
