Answer 1

打开php.ini, 将default_socket_timeout值调大。如：default_socket_timeout=360(默认为-1或60)

Answer 2

我觉得这种奇怪的情况，要么

• 翻墙

• 使用国内 composer 镜像

Answer 3

试试用浏览器请求 https://install.phpcomposer.com/installer, 下载文件后传至服务器 重命名为composer-setup.php

Answer 4

几个解决方案

1. 检查一下代理，如果有设置，先清空掉

     $ echo $https_proxy
     $ unset https_proxy

2. wget https://curl.haxx.se/ca/cacer... 到 /path/to/certs

       # 并设置你的php.ini (php --ini)
       curl.cainfo    = /path/to/certs/cacert.pem
       openssl.cafile = /path/to/certs/cacert.pem
       openssl.capath = /path/to/certs

3. ipv6的问题（官方给的解决方案）

       $ sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"

4. composer diagnose 检查的时候，https FAILED的问题

       $ composer config -g secure-http false

Answer 5

换成国内镜像试试

Answer 6

就是网络差。或者不通。。。
