下面由composer教程栏目给大家介绍关于Composer 安装时要求输入授权用户名密码的问题，希望对需要的朋友有所帮助！
D:\work\dreamland-yii>composer require "saviorlv/yii2-dysms:dev-master"
Authentication required (packagist.phpcomposer.com):
Username:
Password:
[Composer\Downloader\TransportException]
Invalid credentials for 'https://packagist.phpcomposer.com/p/saviorlv/yii2-dysms%24045b85ee8f7a846caecdf82efa78fb4927e19868940b05fbb3ddb6383a10d41f.json', aborting.require [--dev] [--prefer-source] [--prefer-dist] [--no-progress] [--no-suggest] [--no-update] [--no-scripts] [--update-no-dev] [--update-with-dependencies] [--update-with-all-dependencies] [--ignore-platform-reqs] [--prefer-stable] [--prefer-lowest] [--sort-packages] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--apcu-autoloader] [--] [<packages>]...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 Loading composer repositories with package information Updating dependencies (including require-dev) Could not fetch https://api.github.com/repos/bestiejs/punycode.js/tags?per_page=100, please create a GitHub OAuth token to go over the API rate limit 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。
