git push失败，报错fatal: does not appear to a git repository Could not read from remote repository

几周没用git，今天一来托管就报错，下面记录一下解决办法。

$ git push -u origin master
fatal: 'git@github.com/zejun_web' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

这是报错信息，建立了文件夹用了

git init

后，也remote了，结果就是push不上去。

后面检查了一下remote内容

$ git remote -v
origin  git@github.com/zejun_web (fetch)
origin  git@github.com/zejun_web (push)

敢情是remote命令就错了。。这样就知道怎么解决了，
先remove掉添加在远程的origin

git remote rm origin

此时再用

git remote -v

就会发现没有origin了
再正确输入

git remote add origin git@github.com:git-ze/xxxx.git

就可以了。
然后

$ git push -u origin master

remote:
To github.com:git-ze/zejun_web.git
 * [new branch]      master -> master
Branch 'master' set up to track remote branch 'master' from 'origin'.

到这里就成功啦。
网上查了一下还有的说要重新配置邮箱和姓名等信息的。。如果没有添加公钥的话确实
还是要先在GitHub上添加公钥，
如果已经添加过了，可以先用git remote -v命令来检查一下添加的origin是不是代码写错了，写少了。
如果错了就先 git remote rm origin
然后最后就可以push了。

要注意的就是第一次push的话，要加上 -u 在语句里，把本地master分支和远程库的master分支关联起来。
