windows上composer的一些小问题

之前安装过composer，使用的时候突然出了一个错误：

You are running Composer with SSL/TLS protection disabled.

终于在图灵社区找到了结果，原来是我已经‘放弃了’SSL连接，所以我就出现了这个新的异常。尝试使用composer config -g -- disable-tls false 果然，错误没有了。

好吧，上面只是一个错误，继续使用的是出现第二个错误了：

Your requirements could not be resolved to an installable set of packages.  Problem 1    - yiisoft/yii2 2.0.9 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable | 1.12.*@stable -> no matching package found.    - yiisoft/yii2 2.0.8 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.    - yiisoft/yii2 2.0.7 requires bower-asset/jquery 2.2.*@stable | 2.1.*@stable | 1.11.*@stable -> no matching package found.    - yiisoft/yii2 2.0.6 requires bower-asset/jquery 2.1.*@stable | 1.11.*@stable -> no matching package found.    - Installation request for yiisoft/yii2 >=2.0.6 -> satisfiable by yiisoft/yii2[2.0.6, 2.0.7, 2.0.8, 2.0.9].Potential causes: - A typo in the package name - The package is not available in a stable-enough version according to your minimum-stability setting   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

这个时候我不得不承认我其实是没有按照教程走的，导致的
这么多错误，也是蛋疼（血的教训，有现成的教程一定得跟着走，节约时间）
解决方法就是：
composer global require "fxp/composer-asset-plugin:~1.1.1"
