git遇到过的错误

用git也是走了很多弯路。
比如：
这种错误
1.

$ git commit -afatal: Unable to create 'E:/****/.git/index.lock': File exists.Another git process seems to be running in this repository, e.g.an editor opened by 'git commit'. Please make sure all processesare terminated then try again. If it still fails, a git processmay have crashed in this repository earlier:remove the file manually to continue.

解决方法：
使用了$ rm -f ./.git/index.lock

然后我估计是点击了编辑，就出现了这个鬼

<****.github.io/.git/COMMIT_EDITMSG[+][RO] [unix] (18:21 22/07/2016)1,0-1 All

输入:wq!(千万要记住!要加上去，万恶的电脑，少个符号都识别不了，这就是为什么我喜欢人脑)
然后就正常了
还有这种错误：
2.

出现这个问题是因为，没有在github账号添加SSH key，
为了方便，我用了HTTPS协议
