哦，我的zsh几何主题git错误

Question

我最近在我的iTerm上用Oh My Zsh安装了一个新主题。当我启动终端时，它似乎运行良好，但是当我开始使用git并从分支切换时，我收到了一个错误：

_git_branch:4: parse error: condition expected: 1
__gitcomp_nl:compset:5: can only be called from completion function
__gitcomp_nl:compadd:6: can only be called from completion function

这是.zsh主题文件：
