一开始以为是不支持ssl ，检查发现是支持的
php -i | grep -i ssl SSL => Yes SSL Version => OpenSSL/1.0.2r core SSL => supported extended SSL => supported openssl OpenSSL support => enabled OpenSSL Library Version => OpenSSL 1.0.2r 26 Feb 2019 OpenSSL Header Version => OpenSSL 1.0.2q 20 Nov 2018 Openssl default config => /usr/local/etc/openssl/openssl.cnf openssl.cafile => /usr/local/etc/openssl/cacert.pem => /usr/local/etc/openssl/cacert.pem openssl.capath => /usr/local/etc/openssl => /usr/local/etc/openssl SSL support => enabled OpenSSL support => enabled
后来看有人说要更新ssl 秘钥
wget http://curl.haxx.se/ca/cacert.pem
然后在php.ini 配置
curl.cainfo=/usr/local/etc/openssl/cacert.pem openssl.cafile=/usr/local/etc/openssl/cacert.pem openssl.capath=/usr/local/etc/openssl
都没什么效果，看来并不是因为这些
执行composer diagnose 之后结果
composer diagnose

然后逐个解决错误吧，首先是github fail 了，网上google 了下，发现需要设置一个token ,之前怎么不需要呢 ，也是奇怪，那先试试
composer config --global github-oauth.github.com <token>
or
//在composer.json 里加入
"github-oauth":{
"github.com":"{token}" //替换成自己token
}
token 生成在 https://github.com/settings/t...
执行composer diagnose
