最近遇到一個問題，一直不知道如何解決，網上搜到很多方法，都沒效果
一開始以為是不支援ssl ，檢查發現是支援的
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
後來看有人說要更新ssl 秘鑰
wget http://curl.haxx.se/ca/cacert.pem
然後在php.ini 設定
curl.cainfo=/usr/local/etc/openssl/cacert.pem openssl.cafile=/usr/local/etc/openssl/cacert.pem openssl.capath=/usr/local/etc/openssl
都沒什麼效果，看來並不是因為這些
執行composer diagnose 之後結果
composer diagnose
然後逐個解決錯誤吧，首先是github fail 了，網上google 了下，發現需要設定一個token ,之前怎麼不需要呢，也是奇怪，那先試試
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>
token 生成在https://github. com/settings/t...
執行composer diagnose
