使用国内composer镜像安装项目报错

Question

其实从来没用comopser安装成功过。问题和过程如下：
1、在windows上用http://docs.phpcomposer.com/Composer-Setup.exe安装composer
2、Wamp、php都已经安装好openssl也打开。
3、新建一个目录，里面放了composer.json，内容如下：
{
"name":"karpoff/yii2-crop-image-upload",
"description":"Yii2Cropimageuploadwidget",
"homepage":"https://github.com/karpoff/yii2-crop-image-upload",
"license":"BSD-3-Clause",
"type":"yii2-extension",
"version":"0.0.1",
"keywords":["yii2","crop","image","upload"],
"authors":[
{
"name":"AntonKarpov",
"email":"[e-mail]"
}
],
"autoload":{
"psr-4":{
"karpoff\\icrop\\":""
}
},
"require":{
"yiisoft/yii2":"*",
"yiisoft/yii2-imagine":"*",
"mongosoft/yii2-upload-behavior":"*"
},
"repositories":[
{"type":"composer","url":"http://pkg.phpcomposer.com/repo/packagist/"},
{"packagist":false}
]
}
4、然后右键点击，选"ComposerInstall"，报错：
