git 撤销更改_如何撤消Git中的更改

git 撤销更改

You may already know that Git is like a save point system. What you generally learn with Git initially is to learn to save your changes and commit them to a remote repository. But how do you undo a change, and go back to a previous state?

您可能已经知道Git就像一个保存点系统。 通常，您最初使用Git所学的是学习保存更改并将其提交到远程存储库。 但是，如何撤消更改并返回到先前的状态？

That’s what we’re going to cover within this article.

这就是我们将在本文中介绍的内容。

I’ve covered the contents in this article in a video if you like learning by watching instead of reading.

如果您喜欢通过观看而不是阅读来学习，那么我已经在视频中介绍了本文的内容。

本地与远程 (Local vs Remote)

It’s more complicated to undo something that’s already on the remote. This is why you want to keep things on your local until they’re kind of confirmed.

撤消遥控器上已经存在的内容更为复杂。 这就是为什么您希望在事物被确认之前将其保留在本地的原因。

四种常见情况 (Four common scenarios)

We’ll be covering the following four common scenarios

我们将介绍以下四种常见情况

1. Discarding local changes
   放弃本地更改
2. Amending the previous commit
   修改上一次提交
3. Rolling back to a previous commit
   回滚到上一个提交
4. Reverting a commit that has been pushed to the remote
   还原已推送到远程的提交

Note: In the screen shots below, I’ve used the Fork for Mac OS Git Client. You can do the same in other similar Git clients.

注意：在下面的屏幕截图中，我使用了For Mac OS Git Client的Fork 。 您可以在其他类似的Git客户端中执行相同的操作。

方案1：放弃本地更改 (Scenario 1: Discarding local changes)

The first scenario is when you’ve created some changes. They’re not committed yet. And you want to delete these changes.

第一种情况是创建一些更改后。 他们尚未承诺。 您要删除这些更改。

Let’s say we want to create a new feature. We’re going to add some HTML and CSS into the project:

假设我们要创建一个新功能。 我们将在项目中添加一些HTML和CSS：

```

```css
/* In CSS file */
.feature {
  font-size: 2em; 
  /* Other styles */
}

To discard these changes:

放弃这些更改：

1. Go to the staging area
   转到暂存区
2. Select the files where you want to discard changes
   选择您要放弃更改的文件
3. Right click on the files
   右键单击文件
4. Select discard changes
   选择放弃更改

方案2：修改上一次提交 (Scenario 2: Amending the previous commit)

When you have created a commit and you missed out some changes and you want to add these changes in the previous commit message.

创建提交后，您错过了一些更改，并且希望将这些更改添加到上一个提交消息中。

1. Go to the staging area
   转到暂存区
2. Stage the files to commit
   暂存文件以提交
3. Click on the amend checkbox
   单击修改复选框
4. Edit your commit message
   编辑您的提交消息
5. Commit
   承诺

方案3：回滚到上一个提交 (Scenario 3: Rolling back to a previous commit)

You already have a few commits in your local repository. You decide that you don’t want these commits anymore and you want to “load” your files from a previous state.

您的本地存储库中已经有一些提交。 您决定不再需要这些提交，而要从先前的状态“加载”文件。

1. Go into the Git History
   进入Git历史
2. Right click the commit you want to roll back to
   右键单击要回滚的提交

3. Select reset branch to here

   选择重置branch到这里

Note: You can only reset to a commit that hasn’t been pushed into the remote.

注意：您只能将其重置为尚未推送到远程的提交。

方案4：还原已推送到远程的提交 (Scenario 4: Reverting a commit that has been pushed to the remote)

If you have a commit that has been pushed into the remote branch, you need to revert it.

如果提交已被推送到远程分支，则需要将其还原。

Reverting means undoing the changes by creating a new commit. If you added a line, this revert commit will remove the line. If you removed a line, this revert commit will add the line back.

还原意味着通过创建新的提交来撤消更改。 如果添加了一行，则此还原提交将删除该行。 如果您删除了一行，此还原提交将把该行重新添加回去。

To revert, you can:

要还原，您可以：

1. Go to the Git history
   转到Git历史
2. Right click on the commit you want to revert
   右键单击要还原的提交
3. Select revert commit
   选择还原提交

4. Make sure commit the changes is checked.

   确保commit the changes已检查。

5. Click revert
   点击还原
