Composer: nothing to install or update

Question

I want install this. I installed composer, set the environment variable path in w10. Edit the composer.json located in this folder:

C:\Bitnami\wampstack-5.5.29-1\php\PEAR

with this content:

{
"name":"amazonwebservices/aws-sdk-for-php",
"description":"AWS SDK for PHP",
"keywords":["aws","amazon","sdk","s3","ec2","dynamodb"],
"type":"library",
"license":"Apache-2.0",
"authors":[
    {
        "name":"Amazon Web Services",
        "homepage":"http://aws.amazon.com"
    }
],
"homepage": "http://aws.amazon.com/sdkforphp/",
"require":{
    "php":">=5.2.0"
},
"autoload":{
    "classmap": [
        "authentication/",
        "extensions/",
        "lib/",
        "services/",
        "utilities/",
        "sdk.class.php"
    ]
}
}
 {
"require": {
    "katzgrau/klogger": "dev-master"
 }
}

but when I execute this command in my console:

composer require katzgrau/klogger:dev-master

I get:

nothing to install or update

what I did wrong?

Solution

You are reusing the composer.json file of "aws-sdk-for-php". That is probably not your project. And you are in the wrong folder (PEAR). Don't copy and paste composer.json files... anyway:

---

1. Create a new project folder
2. then simply run composer require katzgrau/klogger:1.2.0

You'll get all dependencies fetched into the vendor folder and a fresh composer.json file for your project.
