问题描述
在我的系统上，我没有故意在全局级别设置user.email git配置值.相反，我在每个沙箱中分别对其进行配置.这是因为我需要对不同的项目使用不同的电子邮件地址.
On my system I don't have the user.email git configuration value set at the global level, on purpose. Instead, I configure it individually in each sandbox. This is because I need to use different e-mail addresses for different projects.
不幸的是，有时我忘了在创建新的沙箱时配置该值.在那些情况下，git只是根据它从环境中获得的信息来猜测"一个值.这会导致各种问题，例如，在github上没有将提交归因于我，而将@localhost电子邮件地址追溯给我的那些提交我也不会很幸运.
Unfortunately I sometimes forget to configure the value when I create a new sandbox. In those cases, git just "guesses" a value based on information it gets from the environment. That leads to various problems, for example commits are not attributed to me on github, and I won't have much luck getting those commits with @localhost e-mail addresses attributed to me retroactively.
当我尝试在未配置本地或全局user.email值的情况下提交时，是否可以将git配置为出错而不是猜测?
Is there a way to configure git to error out instead of guessing when I try to commit without a local or global user.email value configured?
推荐答案
现在有一个配置选项.
There is a config option for that now.
指示Git避免尝试猜测user.email和user.name的默认值，而是仅从配置中检索值.
Instruct Git to avoid trying to guess defaults for user.email and user.name, and instead retrieve the values only from the configuration.
因此只需将其设置为true:
So just set this to true like this:
git config --global user.useConfigOnly true
下一次，当您尝试在没有显式设置user.email和user.name的情况下进行提交时，您将收到错误消息.
And next time when you try to make a commit without user.email and user.name explicitly set you will get an error.
$ git commit
*** Please tell me who you are.
Run
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: no email was given and auto-detection is disabled
