無法從遠程簽出新分支

Question

我這樣做：

git fetch --all
Fetching origin
remote: Counting objects: 242, done.
............
From bitbucket.org:xxx/xxx
   xxxx..xxxx  develop    -> origin/develop
 * [new branch]      branch1 -> origin/branch1
   xxxx..xxxx  master     -> origin/master

然后我做了：

git checkout branch1
error: pathspec 'branch1' did not match any file(s) known to git.

但是應該已經簽出到branch1。 這是怎么回事？

Answer 1

沒有名為branch1本地分支。 你要說

git checkout -b branch1 origin/branch1

這將創建一個名為branch1的本地分支，該分支將跟蹤遠程分支branch1 。

Answer 2

通過實驗：

[wei2912@localhost wee-repo]$ git init
Initialized empty Git repository in /home/wei2912/tmp/wee-repo/.git/
[wei2912@localhost wee-repo]$ git checkout -b branch1
Switched to a new branch 'branch1'
[wei2912@localhost wee-repo]$ git checkout -b master
Switched to a new branch 'master'
[wei2912@localhost wee-repo]$ git checkout branch1
error: pathspec 'branch1' did not match any file(s) known to git.
[wei2912@localhost wee-repo]$ git branch -a
[wei2912@localhost wee-repo]$ 

在首次提交之前，您不能創建多個分支（如果考慮的話，這很有意義）。 在創建從初始分支（已選擇要提交到的分支）的其他分支之前，您需要簽出到該分支並對該分支進行提交。

[wei2912@localhost wee-repo]$ git status
# On branch master
#
# Initial commit
#
nothing to commit (create/copy files and use "git add" to track)
[wei2912@localhost wee-repo]$ touch test.txt
[wei2912@localhost wee-repo]$ git add test.txt
[wei2912@localhost wee-repo]$ git branch -a
* master
[wei2912@localhost wee-repo]$ git checkout -b branch1
Switched to a new branch 'branch1'
[wei2912@localhost wee-repo]$ git branch -a
* branch1
  master

如您所見，在進行初始提交之后，您可以創建從master分支分支出來的分支。
