我正在尝试创建一个新包，php artisan workbench vendor/packagename但是当我运行它时，我得到了
Package workbench created!
Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package illuminate/support could not be found in any version, there may be a typo in the package name.
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://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.
Read <http://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
illuminate/support存在于下面，因此laravel/framework/src/Illuminate/Support不太确定可能是什么原因造成的。
生成的 composer.json 文件需要以下内容
"require": {
"php": ">=5.4.0",
"illuminate/support": "5.0.*"
},
不确定illuminate/support版本5.0是否是导致问题的原因？
问题解决了
我必须在半生成的包中手动修改minimum-stabilityfromstable到，然后运行以完成它。devcomposer update
