Let's talk about how to remove local images on github

GitHub is a very popular code hosting platform that provides very detailed version management, collaborative development and workflow management tools. When we use it, we often need to modify and submit the local code base, and synchronize with the remote warehouse. However, in actual work, we often encounter unexpected events. For example, some errors occur when submitting code locally. At this time, we need to roll back to the previous version. In this process, we often encounter some problems caused by inconsistencies between the local code base and the remote warehouse. This article will explain how to solve these problems by removing local images.

"Local image" in GitHub

In GitHub, each warehouse corresponds to a local code library. GitHub's version management tool, Git, will automatically copy all files and folders in the remote code base to the local, and create a local code base that is completely consistent with the remote code base, including a complete version history. This identical code base is locally called a "local clone".

The local image and the remote code base are synchronized through Git. When you add some new code to the local image, you need to commit these changes to the remote code base. Similarly, when other team members make changes on the remote code base, you need to synchronize these changes to your local image.

If you are working on different branches with other team members, you need to create a new branch locally and make relevant modifications and commits. Once your changes are approved, they can be merged into the master branch. At the same time, your local branch will be updated and updated based on the master branch.

The significance of removing the local image

Although "local image" is a very important concept in GitHub, in some cases, it is not what we want. The following are several situations where local images need to be removed:

1. Rolling back to an earlier version: When you make some low-level mistakes when using local images to modify the code, you need to roll back to the exact same remote code. library or earlier versions, you need to remove the local image at this time.
2. Conflicts when synchronizing code across multiple terminals: If you use GitHub for code development on different machines at the same time, modify the same code base, and then submit the modifications to the remote code base at the same time, code conflicts may occur. At this time, you need to use the method of removing the local image and merge the code manually.
3. Force to update the local branch: When you perform some operations on the local branch, but the code is restored due to the merge problem of other branches, causing the branch to be out of sync, then you need to force the local branch to be updated.

How to remove the local image

The following is how to remove the local image:

1. Copy the local image to a new directory, this directory is the same as Next to the local image, name it "for example, test".
2. Delete local folders like ".git": "rm -rf .git".
3. Reinitialize Git in the new directory: Run "git init" in the new directory.
4. Push the new directory to the GitHub remote code repository: In the new directory, re-add the remote alias and URL, and then push the new directory to the remote code repository.
5. Merge local modifications: Copy local modifications from the old directory to the new directory, and then commit to the new branch in the new directory.
6. Delete the old directory: Delete the old directory because you are now using the new directory.

In this way, you can delete the local image and solve the code conflict problem to a certain extent.

Summary

GitHub is a very good collaborative development platform that provides very good version management and collaborative work functions. When using it, we often need to synchronize the local code base to the remote warehouse and achieve collaborative work through changes in the remote warehouse. The local image plays a very important role in this process. But in some cases, in order to solve problems such as code conflicts, we need to remove the local image. In this case, we can use the method introduced in this article to solve the problem.
