Error with git: " already exists and is not a valid git repo"
git, github, oauth
Solution
Even if the folder doesn't exist, check the index status:
cd libs/OAuth
git ls-files -- functions
If there is an entry registered in the index, you will need to remove it before being able to add your subrepos as a submodule. (as explained in "Issue with adding common code as git submodule: “already exists in the index”")
All this assumes that you are at the root folder of a currently cloned repo, which will act as the parent repo of any submodule you would declare.
Problem
It is seying that I cannot do this: ``` git submodule add -f git@github.com:thephpleague/oauth2-server.git libs/OAuth/functions ``` Because of this: 'libs/OAuth/functions' already exists and is not a valid git repo I just don't get it. It does not exists anywhere. Is there another git config file hidden on my computer that I don't know of or something? I tried deleting .git and pulling everything again that did not do anything. Any ideas? I also tried this: ``` git ls-files --stage functions ``` When I was inside of libs/OAuth and I got nothing. Then I tried this: ``` sudo git rm --cached functions ``` I got this error: ``` fatal: pathspec 'functions' did not match any files ``` I also tried this: ``` sudo git rm -r --cached functions ``` And got the same previous error.
