Composer 安装时要求输入授权用户名密码？

D:\work\dreamland-yii>composer require "saviorlv/yii2-dysms:dev-master"

    Authentication required (packagist.phpcomposer.com):
      Username:
      Password:

需要改为中国的composer源，请求接口显示的“There is an arrear problem with this JSS account that prevents the operation from completing successfully” 翻译为：“此JSS帐户存在欠费问题，导致操作无法成功完成”.....

改用国内镜像源就好了 https://pkg.phpcomposer.com/

composer config -g repo.packagist composer https://packagist.phpcomposer.com

然后我这里又出现一个问题

D:\work\dreamland-yii>composer require "saviorlv/yii2-dysms:dev-master"
./composer.json has been updated

Head to https://github.com/settings/tokens/new?scopes=repo&description=Composer+on+JL-HOST-008-PC+2018-10-13+0916
to retrieve a token. It will be stored in "C:/Users/niuben/AppData/Roaming/Composer/auth.json" for future use by Composer.
Token (hidden):

它让我输入一个token？？？

经过网上查询 这是因为Composer 没有添加github密钥

解决方法

进入 https://github.com/settings/tokens 点击 「Generate new token」（记得先登录哦）

新建一个 Token，输入描述，选择默认新建就行，然后就会得到一个 Token，然后把这个值粘贴过去就 OK 了。
