Github不会缓存我的密码

Question

$ git config --global credential.helper osxkeychain
warning: credential.helper has multiple values
error: cannot overwrite multiple values with a single value
       Use a regexp, --add or --replace-all to change credential.helper.

git config -l
credential.helper=osxkeychain
user.name=ewan-delanoy
user.email=<my e-mail here>
push.default=simple
credential.helper=osxkeychain
credential.helper=osxkeychain
credential.helper=osxkeychain
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true
core.ignorecase=true

remote.origin.url=https://github.com/ewan-delanoy/Ludlow-Street.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
branch.master.remote=origin
branch.master.merge=refs/heads/master

更新：正如当前答案所建议的，我还给出了git config-l--show-origin的输出：

您可以简单地编辑全局文件以只保留一个条目：

git config --global --edit

还要检查该设置的设置位置：

git config -l --show-origin

然后删除存储在其中的旧凭据。
下一次推送将再次询问您的凭据，但将缓存它们。
