Today, when using git to add a remote GitHub warehouse, you will be prompted with an error: fatal: remote origin already exists
Finally, the solutions are as follows:
1. Delete the remote git warehouse first
$ git remote rm origin
2. Add remote git warehouse
$ git remote add origin [email protected] :FBing/java-code-generator
If an error is reported when git remote RM origin is executed, we can manually modify the contents of the gitconfig file
$ vi .git/config
An error is reported when the local warehouse code (GIT push) is uploaded to the GIT warehouse:
fatal: No configured push destination.
Either specify the URL from the command-line or configure a remote repository using
git remote add <name> <url>
and then push using the remote name
git push <name>
Solution:
create a new warehouse in Git warehouse and copy the warehouse URL link:
git remote add origin https://github.com/xxxxx/xxxxx.git
git push -u origin master

Your local changes would be overwritten by merge. Commit, stage or revert them to proceed
Cause: git conflict
1. Use the GIT repository stash changes command to save your changes
At this time, you will find that the modified parts are gone and return to the original state
2、pull
Download the code on GIT
3、git-repository-Unstash changes
Take out your own code and compare and merge the code
In the comparison page, the version in Git library is on the left, the original version is in the middle, and your own version is on the right
Execution error:
[root@localhost learngit_2]# git remote add origin https://github.com/shengleqi/gitskills.git [root@localhost learngit_2]# git push -u origin master error: The requested URL returned error: 403 Forbidden while accessing https://github.com/shengleqi/gitskills.git/info/refs fatal: HTTP request failed
Repair method:
You can see the bold red text above ( the requested URL returned error: 401 authorization required ), which is caused by a permission problem. You can modify the. Git/config file and add a user name and password:
1) Edit the. Git/config file
2) Find the URL variable under [remote “origin”]
3) Modify URL= https://github.com/user/test.git , modify to URL= ssh://git @Github.com/user/test.git, save after modification
4) Synchronization through git push origin master is successful
Amend as follows:
[root@localhost learngit_2]# cat .git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = ssh://[email protected]/shengleqi/gitskills.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master

After installing git, an error is reported in vscode that git cannot be found:
Find git in C:/program files/git/bin/git.exe
Find git in C: \ program files \ git \ CMD \ git.exe
Find git in C: \ program files (x86) \ git \ CMD \ git.exe
Find git in C: \ program files \ git \ CMD \ git.exe
Find git in C: \ users \ administrator \ appdata \ local \ programs \ git \ CMD \ git.exe
Git installation not found.
Then find the GIT directory and open the two files:
Enter git — version in CMD, and the same error will be reported:
Microsoft Windows [version 10.0.16299.15]
(c) 2017 Microsoft Corporation。 All rights reserved
C:\windows\system32> git -version
fatal: open /dev/null or dup failed: No such file or directory
Solution:
The reason I found it on the Internet is that there is a problem with the null.sys file under C: \ windows \ system32 \ drivers, so I found another null.sys on the network disk to replace the original one, and then restart the computer
Network disk address of null.sys https://pan.baidu.com/s/1kwKmnHSBjfonHUFenveXAA (it can also be found in my network disk – related GIT). Of course, this solution is limited to win10
(also, the command used to check the GIT version is: git — version, with two bars)
summary
When developing new functions in the dev development branch, there is an emergency bug in the master branch that needs to be fixed. The command git stash can temporarily store the code changes of the current dev branch and switch to the master branch to solve the emergency bug. Today, I encountered a git error message that I restored the temporary code after switching back to the dev development branch, but the code could not be submitted after restoration, resulting in Git process conflict. The specific error information is as follows:
Another git process seems to be running in this repository, e.g.an editor opened by ‘git commit’. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.After the research on the solution of error information, we found a specific and effective solution
solutions
Main idea: git process has been opened in an editor. Please make sure all processes are finished before trying. If it still fails, git in the last run may crash. Please remove this file manually before continuing
1. Nature of the problem:
Windows has a lock mechanism for process management. Under normal circumstances, the process runs = = > Process lock = = > Process end = = > The process is unlocked. Maybe I accidentally shut down git while switching branches, which led to git crash, so the locked index.lock didn’t unlock, resulting in conflict
2. Solution:
Open the project folder and find the index. Lock file in the. Git file. The file that needs to be manually deleted in the error message is the index. Lock file. After deleting, go back to GIT and continue to operate the command, which perfectly solves the conflict problem of GIT process
summary
When operating git command, we need to pay attention to the status of GIT process. The most important thing is that we need to be careful when operating git command. Even when we encounter urgent tasks, we need to be calm to solve them. We can’t eat hot tofu if we are anxious

After installing git in window, generate SSH key in CMD. Use SSH keygen
During the command, I was prompted with the error of “could not create directory ‘/ /. SSH”. My colleague said that he had encountered the same error before, which was caused by the lack of system variables. At that time, he helped me add the variables, but I didn’t see which variable was added. Today, I looked up the information on the Internet and found out that the environment variable of home was added. My job is to add home = C/users. Then skills are generated automatically. Excerpt【
Digression: because it’s a Windows environment, it may have been affected when cygwin was installed a few days ago
In addition, in the actual use process, we found that although cygwin imitates the Linux environment under windows, in many cases, there will be obscure problems, and there is no error prompt. For example, this time, using the command line of cygwin and git, everything else is normal, but when submitting the code, it will lose its response (not stuck, but after entering, it will not submit the code and there is no output) and there is no error prompt. Finally, it’s done with the built-in CMD of windows

In addition, the note I learned is the misunderstanding of GIT. I used to think that Git is GitHub, but I learned that they are different concepts through video learning. Git is actually more like a technology, and GitHub is a platform to provide the use of this technology
