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": "Yii 2 Crop image upload widget",
"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": "Anton Karpov",
"email": "karpoff@bk.ru"
}
],
"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 "Composer Install"，报错：
Your requirements could not be resolved to an installable set of packages.
Problem 1
- yiisoft/yii2 2.0.1 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stabl
e -> no matching package found.
- yiisoft/yii2 2.0.0 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stabl
e -> no matching package found.
- yiisoft/yii2 2.0.1 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stabl

- yiisoft/yii2 2.0.0 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stabl
e -> no matching package found.
- Installation request for yiisoft/yii2 * -> satisfiable by yiisoft/yii2[2.0
.0, 2.0.1].
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your min
imum-stability setting

5、求安慰
你漏装了fxp/composer-asset-plugin
composer装上这个就行了
仔细看教程啊。。。
