git 添加代码出现以下错误：
fatal: Unable to create 'F:/wamp/www/ThinkPhpStudy/.git/index.lock': File exists.
If no other git process is currently running, this probably means a git process crashed in this repository earlier. Make sure no other git process is running and remove the file manually to continue.分析问题：出现以上问题是由于运行Git命令两次。然后锁定文件被解锁。
解决办法：如果你仍然得到这个问题，请尝试：
rm F:/wamp/www/ThinkPhpStudy/.git/index.lock'
当然了也可以直接找到这个文件直接删除了即可。
