I'm getting the above error when running composer install --working-dir=/path/to/directory
In case you're wondering: I had a hard drive failure so I needed to re-install composer and well... everything. After installing composer, navigating to the directory with the composer.json file and running composer install would result in an error that composer couldn't find a composer.json file, hence the --working-dir flag.
The project is a Laravel 4.2 project. We have everything in a git repo with the exception of the vendor folder. We figured we would just run composer install and all would be right in the world - and it was.
I ran composer install --verbose and received the following:
Exception trace:

Any ideas would be appreciated. Not sure why I'm suddenly having these problems. A week or two ago a co-worker was able to run all of the same steps without error.
回答1:
As it turns out, the main problem was the starting directory of gitbash.
When I installed it, I changed the starting directory to be c:\users\[me]\My Documents
Even though this directory had sub-directories, and I could cd into them; running an ls would produce 0 results.
I ended up changing the starting directory to c:\users\[me]\Documents and everything worked fine. Composer found the composer.json file and all other commands worked. Lesson learned.
