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/

  

 

  
1
 

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
