在新克隆的git repo中，我無法檢出到新分支

Question

我只是克隆了Linux內核代碼，然后當我嘗試簽出到新分支時，我發現它由於本地更改而失敗。

我很困惑，為什么新克隆的代碼可能會有所謂的本地更改？ 最后，我使用“ git checkout -f -b xxx ”強行檢出到新分支，以放棄本地更改，但是我仍然想知道是否有成功的檢出而不是強制的優雅方法？

Answer 1

在我看來，一個無關的過程正在更改您的工作目錄。

為了避免這種復雜性，只需專門克隆到目標分支中即可：

git clone \
-b linux-4.2.y \
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
