trouble in using git commit -m

Question

When running git commit -m "Commit message" It returns the error message:

fatal: empty ident name (for ((null))) not allowed

and then asks for the account's default identity.

See the command prompt screenshot for more details.

Answer 1

Just as the text in the screenshot says, you need to tell git who are you committing the code as, by using e.g.:

git config --global user.name "John Smith"
git config --global user.email "[email protected]"

Answer 2

You need to set your user name and email address, which sets your identity before you can commit anything. Please follow the instructions here.
