在composer.json中添加了一个git地址；composer update 报错

在composer.json中添加了一个git地址；composer update 报错，不知道是什么原因导致的，如图：

问题补充：

在BAE包里面添加composer.json 后 重新composer update

    
    Your requirements could not be resolved to an installable set of packages.

  Problem 1

• The requested package zcbo/bae 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://getcomposer.org/doc/04-schema.md#minimum-stability>; for more details.
  

  Read https://getcomposer.org/doc/articles/troubleshooting.md for further common problems.

  项目的composer.json如下
  {

"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {

"php": ">=5.5.9",
"zcbo/bae":"master",
"laravel/framework": "5.2.*"

},
"require-dev": {

"fzaninotto/faker": "~1.4",
"mockery/mockery": "0.9.*",
"phpunit/phpunit": "~4.0",
"symfony/css-selector": "2.8.*|3.0.*",
"symfony/dom-crawler": "2.8.*|3.0.*"

},

......

追问：
已将master 改成 dev－master 报错信息如下：
另外，怎么使用tag？

你要确定你的git仓库是一个正确的composer项目，这里已经写明了，你定义的仓库里并没有定义composer所必须的composer.json，composer是不能识别这个仓库的。

补答：
master分支默认会被解析成dev-master这个版本号，所以你直接用master做版本号是不行的。另外，最好通过tag明确一个版本并使用。
