svn commit failed: Could not use external editor to fetch log message

svn commit时出错

svn: Commit failed (details follow):

svn: Could not use external editor to fetch log message; consider setting the $SVN_EDITOR environment variable or using the --message (-m) or --file (-F) options

svn: None of the environment variables SVN_EDITOR, VISUAL or EDITOR are set, and no 'editor-cmd' run-time configuration option was found

原因：svn拿不到log message

解决方法2种

1：附上参数 --message (-m) 或 --file (-F)即可

比如：svn ci -m "fix bugs in xxx.cpp"

或者将log message写到指定文件中，如message.log，然后svn ci -F message.log

2：设置SVN_EDITOR

exprot SVN_EDITOR=vim

或在~/.bash_profile中添加一行：export SVN_EDITOR=vim
