问Git，如何将源/主节点重置为提交？

EN

git reset --hard e3f1e37

# On branch master
# Your branch is behind 'origin/master' by 7 commits, and can be fast-forwarded.

#   (use "git pull" to update your local branch)
#
nothing to commit, working directory clean

$ git checkout origin/master
Note: checking out 'origin/master'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

HEAD is now at 2aef1de... master problem fixed for master. its okay now.

$ git reset --hard e3f1e37
HEAD is now at e3f1e37 development version code incremented for new build.

$ git commit -m "Reverting to the state of the project at e3f1e37"
# HEAD detached from origin/master
nothing to commit, working directory clean

$ git checkout master
Switched to branch 'master'
Your branch is behind 'origin/master' by 7 commits, and can be fast-forwarded.
