我的情况非常愚蠢，使git设置不必要地复杂。当我的承诺（很多次）使我回到过去时，我花了几天的时间梳理头发。
我希望有人进行分析，并就其如何发生做出解释，只有在明确这一点之后，我们才想摆脱这种混乱。对于git入门者来说，这也是一个很好的案例研究。
因此，纯粹出于疏忽，我在~/nlp中初始化了一个git repo，在~/nlp/annotate中初始化了另一个git repo。在意识到有两个存储库之前，我开始提交并推送到同一远程服务器（托管在gitlab.com上）。
似乎这还不够，我也意外地将一个远程定义为[remote "nlp"]，将另一个远程定义为[remote "origin"]。 （也许年龄正在赶上我）。
然后最重要的是，我有一台服务器（AWS ubuntu机器，通常在其中我git pull编写代码，有时git push到同一gitlab存储库。
因此，实际上，我们有3个本地存储库推送到同一远程主机（具有不同的名称）。
令事情复杂化的是，服务器和我的本地计算机上有独立的.gitignore文件，其中设置了不同组文件。
为进行诊断，我将从三个本地存储库的每一个中复制git branch和git log的输出。
