The fatal: not a git repository error occurs when you try to run a Git command but are not inside a Git repository. A Git repository is a collection of files and information regarding past changes made in them. Most of the Git commands must be executed against a Git repository. For example, if you run git push -u origin master outside of a git repository, Git will simply not know what to push and where to push. The error above, fatal: not a git repository (or any of the parent directories): .git, states that you tried to execute a repository-specific command, outside of the Git repository. Here are some reasons why this error might occur: You are in the wrong working directory You mistyped the path to the repo You didn't initialize the Git repository Your HEAD file is corrupted Here are quick steps you can try to fix this error: Make sure you've navigated to the right directory (check with ls or dir) Check if you mistyped the path to the repo Initialize your repository with git init or by cloning an existing repo See more details below on the reasons for the fatal: not a git repository error, how to fix it, and our suggestions for preventing this annoying error in the first place.

Conclusion Why does the “fatal: not a git repository” error occur? The fatal: not a git repository error makes it clear that you’re not in a git repository. There can be a few reasons why the error occurs: You are in the wrong working directory: You tried to run the command but did not navigate to the project folder where the git repository (git folder) is located. You mistyped the path to the repo: Double check your git command and make sure you typed the correct path. You didn't initialize the Git repository: You are in the project directory, but you didn’t initialize the Git repository for that project folder. Your HEAD file is corrupted: You can run the command cat .git/HEAD and see that the HEAD branch is working properly and includes the branch you are working on. To fix “fatal: not a git repository”, try these steps Make sure you have navigated to the right directory To solve the first two situations, in which you are in the wrong directory or mistyped the path to the repo, check the folder in which you are currently trying to run the command. You can check the current folder with ls in Linux or dir in Windows. Also make sure you have not mistyped the path to the repo. Is that the correct folder? If not then simply use the cd command to navigate to the correct path. There is a simple trick that you can use in Windows to be sure that you always open a command prompt in the correct folder. Navigate to the project directory using the file explorer and then type in the search bar, cmd. This will open a command prompt to the current folder path. The trick for always opening a command prompt in the correct folder Initialize your repository If the problem is that you didn’t initialize your git repository, here is how to do that: You need to navigate to the correct folder and then run the command git init, which will create a new empty Git repository or reinitialize an existing one. Alternatively, clone an existing repo into your project folder. Preventing “fatal: not a git repository” When you run a Git command, the first step Git will take is to determine the repository you are in. To do this, it will go up in the file system path until it finds a folder called .git. Basically, the repository starts with the directory that has a .git folder as a direct child. To prevent the fatal:not a git repository error, you need to make sure that you are in a Git repository before running any commands. One way you can do this is to check for the existence of the .git folder. That period in front of the .git folder means that it’s a hidden folder. Therefore, it will not appear in the file explorer unless you have explicitly set it to show hidden folders. On Windows, you can do this from the iew tab. Enable hidden items in Windows from the View tab If you are on Linux or you use a console emulator that allows you to execute Linux commands, you can run the ls command with the flag -a to lists all files including hidden ones. Linux command to list all files Another quick solution that you can use to check that you are inside a Git repository is to run the git status command. This command will show the current state of the repository if the current folder is part of a Git repository. How do Git repositories work? Git errors can be confusing, especially if you’re a beginner. This confusion mainly occurs because users are taught to create a connection between problem and solution, where someone encounters a problem and then looks for and uses a solution generally valid without trying to understand too much about the cause of the problem This simple problem-solution connection is enough for most issues on Git: clone a repository, write some code, commit the changes and push the commits; or clone a repository, create a new branch, write some code, merge the branches and solve the conflicts. However, learning how Git works and its basic concepts will help you understand the technology you are working with and even do much more than those simple use cases described above. Here’s some basic information to help you better understand how Git repositories work. First and foremost, Git is a Distributed Version Control System (DVCS). With Git, we have a remote repository stored on a third-party server and a local repository stored in our local computer. Therefore, one can find the code in more than one place. Instead of having just one copy on a central server, we have a copy on each developer’s computer.Source: Working with Git Git, like any other software, must first be downloaded and installed in order to be used. You can even run the git --version command to see what your current version of Git is. The first step to using a repository is to either clone one if you have access to it or to initialize one. git clone and git init These commands will create a new folder named .git, which will contain all the information about your repository that Git tracks: commits, branches, history, and so on. The workflow of contributing to a Git repository is the following: 1. Stage the files The first step is to add the files you want to add to a repository in the staging area. The purpose of this staging area is to keep track of all the files that are to be committed. You can stage files using the git add command or git add . to stage all the files. Source: What are the differences between git file states 2. Commit the changes The second step is to commit the changes. In this step, all the files that were added to the staged zone will be added to the local repository. The command for this is git commit -m "". The message should be something relevant about the changes you have added. 3. Push the code The last step is to push your changes from your local repository to the remote repository with the help of the git push command. What are some common Git errors? Fatal: not a git repository (or any of the parent directories): .git is just one of many other errors that can occur when working with Git. Here is a list of other common errors that may occur along with a brief explanation. 1. Permission denied Permission denied when accessing 'url-path' as user 'username' Git repositories can be of two types: public or private. In a public Git repository, everyone can view the code and clone it on their local machines. For the private ones, you need to be authenticated on the platform that the repository is hosted on in order to clone it onto your computer. At the same time, you need to have explicit rights to it. The error stated above indicates that you possess an authenticated useraddname-password pair, but you do not maintain the files in the repository you are accessing. Thus, your assigned role in the repository must be increased to at least that of a maintainer or some similar position that the distribution platform provides, like maintainer, developer, admin, and so on. 2. Failed to Push Some Refs git push rejected: error: failed to push some refs Source: What are the differences between git file states The purpose of Git is to collaborate and share work within a project while all the participants contribute to the same code base. One common scenario is when someone else pushes some code to the same branch you are working on, and you are trying to make your changes as well. The above error indicates that there is one more commit that was pushed to the same branch, but you don’t have that commit on your local machine. To fix this, you can easily run a git pull origin , solve the conflicts if any, and then run git push origin to push your changes as well. Learn more in our detailed guide to failed to push some refs to. 3. fatal: A branch named already exists Most VCS (version control systems) have some form of support for branching mechanisms, including Git. Branches can be created directly in the remote repository, or they can be created locally and then pushed to the remote repository. To create a new branch locally, you can run either: git branch
