I am attempting to install Composer under Windows 7 Ultimate. Unfortunately, whenever I run a command, Composer generates an fopen() exception (see below).
My guess is that an empty filename is being passed somewhere, possibly as the result of a configuration error.
In testing I have I have deleted and reinstalled Composer, tested against two versions of PHP and checked my GitHub connection / updated the interface.
An example of the error (it's the same whatever I do) is as follows:
? composer -vvv diagnose
Checking platform settings: FAIL
The xdebug extension is loaded, this can slow down Composer a little.
Disabling it when using Composer is recommended.
Checking git settings: Executing command (CWD): git config color.ui
[ErrorException]
fopen(): Filename cannot be empty
