バグのエラー - 未定義のメソッド `gsub！ ' nilClass（NoMethodError）

Question

私はCentOS 7 VMを起動する迷惑なインスタンスをインストールして実行しようとしています。理想的には、ソフトウェアを使ってVMをプロビジョニングすることができます。

残念ながら、私は浮浪者を起動しようとするたびに、このエラーを取得しておいてください。

C:\Users\tdias\Desktop\Vagrant> 

私はアンインストールして、それを再インストールしようとしましたが、それは働いていません。私は上記のファイルをチェックし、これを見つけました：

# This takes any path and converts it from a Windows path to a 
    # Cygwin or msys style path. 
    # 
    # @param [String] path 
    # @return [String] 
    def cygwin_path(path) 
     begin 
     # We have to revert to the old env 
     # path here, otherwise it looks like 
     # msys2 ends up using the wrong cygpath 
     # binary and ends up with a `/cygdrive` 
     # when it doesn't exist in msys2 
     original_path_env = ENV['PATH'] 
     ENV['PATH'] = ENV['VAGRANT_OLD_ENV_PATH'] 
     cygpath = Vagrant::Util::Which.which("cygpath") 
     cygpath.gsub!("/", '\\') 
     process = Subprocess.execute(
      cygpath, "-u", "-a", path.to_s) 
     return process.stdout.chomp 
     rescue Errors::CommandUnavailableWindows => e 
     # Sometimes cygpath isn't available (msys). Instead, do what we 
     # can with bash tricks. 
     process = Subprocess.execute(
      "bash", 
      "--noprofile", 
      "--norc", 
      "-c", "cd #{Shellwords.escape(path)} && pwd") 
     return process.stdout.chomp 
     ensure 
     ENV['PATH'] = original_path_env 
     end 
    end 

どのように修正する方法を知っていますか？

Answer 1

このラインはあなたの問題です：

cygpath.gsub!("/", '\\') 

あなたは「\」を使用して、文字列内のすべての「/」に変更しようとしているが、あなたはgsubを使用する場合はない「/」は、あなたのテキストではありませんinsted gsub!の場合、このエラーは発生しません。
