Composer无法在既定目录找到composer.json文件，无法create project

SunValley

我在windows7下的PHPstudy使用composer(右键PHPstudy-其他高级应用-composer)，要本地安装flarum于phpstudy/www/www.future.com 文件夹中。
PHPstudy版本是2016，PHP版本是7。
1.composer config没有反应，不能换源（源是中国全量镜像）
2.composer create-project提示没有composer.json（composer.json不是create-project一并创建的吗？就像经典笑话winrarsetup.rar一样）
已尝试的解决办法（演示网址或图片）：1.composer self-update到最高版本
2.手动创建过composer.json，然后发现flarum能正常下载，但是出现在了vendor文件夹，和其他的require一起。
3.composer diagnose 一切正常
4.80端口正常
5.复制了一下官网别人的composerjson再进行安装
