国内互联网某种神秘的力量让Composer变得越来越不稳定。 如果此种情况已经严重影响您的心情,请尝试在您的composer.json添加以下代码
{
"repositories": [
{
"packagist": false
},
{
"type": "composer",
"url": "https://packagist.phpcomposer.com"
}
]
}
通过下面的命令,您可以观察速度提升的效果
$ composer update -vvv
但是Composer我也安装不了啊喂~
我们为composer installer也做了镜像,您可以尝试:
$ curl -sS https://github.com/52fhy/composer/raw/master/bin/installer | php
如果没有安装curl,尝试以下命令(PHP你总得装吧喂~)
$ php -r "readfile('https://github.com/52fhy/composer/raw/master/bin/installer');" | php
当然,如果您不需要检查运行环境,也可以直接下载(一般来说直接下载就可以用):
https://github.com/52fhy/composer/raw/master/bin/Composer-Setup.exe
https://github.com/52fhy/composer/raw/master/bin/composer.phar
官网地址:
https://getcomposer.org/Composer-Setup.exe
https://getcomposer.org/composer.phar

安装完毕,可以查看命令帮助:
$ composer
