I tried to install the phpunit for composer in Windows 7, but is not allowing.
Nor the phpunit and no other tool/package/framework.
The error you’re displaying is this:
and my file of json that’s the one:
{
"require-dev": {
"phpunit/phpunit" : "*"
},
"autoload" :{
"psr-0":{
"Example":"lib"
}
}
}
command to "rotate" the composer
composer install
Below are the details of composer
