I'm having a problem with composer. When I try to run any composer actions update install dump-autoload, I am getting an exception I can't seem to figure out.
[Symfony\Component\Process\Exception\RuntimeException]
A temporary file could not be opened to write the process output to,
verify that your TEMP environment variable is writable
I've changed nothing on my server, only some updates, but suddenly I am getting this error.
I'm also not sure how to find which temp folder it is talking about. I've changed the permissions for every temp folder I can think of. But nothing seems to work.
c:\temp
c:\Windows\Temp
c:\Users\%Username%\AppData\Local\Temp
So I run sys_get_temp_dir (); in php and it says c:\Windows\Temp is the temp directory. Again, I've made sure the permissions are good.
I'm also running the command from Git Bash as administrator. If that for some reason makes a difference.
I am using
PHP vesion 5.4.24
composer latest version
Windows Server 2008 R2
Edit: The problem was solved by installing updates for Windows. We believe the problem started from another windows update 4 days ago. I apologize for not having much more information.
