下面由composer教程栏目给大家介绍解决composer错误：Composer\\Downloader\\TransportException的方法，希望对需要的朋友有所帮助！

 [Composer\\Downloader\\TransportException]
  The "http://packagist.org/packages.json" file could not be downloaded: failed to open stream: HTTP request failed!create-project [-s|--stability="..."] [--prefer-source] [--prefer-dist] [--repository-url="..."] [--dev] [--no-dev] [--n
o-plugins] [--no-custom-installers] [--no-scripts] [--no-progress] [--keep-vcs] [--no-install] [--ignore-platform-reqs]
[package] [directory] [version]

解决方法禁用https请求，改用http方式。所以我们在composer.json文件中设置一个本地或全局的composer配置config

方法一：命令行composer config secure-http false。通过命令修改composer.json，效果等同方法二。

方法二：直接改composer.json,给“config”项中加上"secure-http": false

"config" : {  
        "vendor-dir" : "packages",        "secure-http": false  }

全局配置（推荐）

composer config -l -g//切换到国内源  阿里composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/composer config -g --unset repos.packagist
