方法有三种：

1.修改命令 
git remote set-url origin [url] 
例如：Git remote set-url origin gitlab@gitlab.chumob.com:PHP/hasoffer.git

2.先删后加 
git remote rm origin 
git remote add origin [url]

3.直接修改config文件

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
[remote "origin"]
    url = https://github.com/sunsteam/android-zxingLibrary.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master
