使用发布的包

问题
1、提示composer.json找不到
[RuntimeException]
No composer.json present in the current directory (./composer.json),
this may be the cause of the following exception.
echo '{}' > composer.json
2、包不存在
通常我们使用的是阿里云的镜像地址，刚提交的包，可能没有及时同步，可以临时设置一下包下载地址
$ composer config repo.packagist composer https://packagist.org/
3、版本号找不到
[InvalidArgumentException]
Could not find a version of package mouday/more-echo matching your minimum-stability (stable).
Require it with an explicit version constraint allowing its desired stability.
给项目打一个版本号的标签
git tag 1.0.0 git push --tag
