git分支无法获取

git 上新建的分支，本地想要拉取该分支，但是找不到这个分支

使用  git branch -a  也看不到该分支

使用命令：

git checkout -b branch_nameA origin/branch_nameB

有如下报错信息：

“

fatal: Cannot update paths and switch to branch 'branch_nameA' at the same time. 
Did you intend to checkout 'origin/branch_nameB' which can not be resolved as commit?

”

解决方法：

git remote update
git fetch
git checkout -b branch_nameA origin/branch_nameB
