最近遇到一個問題，一直不知道如何解決，網(wǎng)上搜到很多方法，都沒效果

一開始以為是不支持ssl ，檢查發(fā)現(xiàn)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

后來看有人說要更新ssl 秘鑰

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

都沒什么效果，看來并不是因為這些
執(zhí)行composer diagnose 之后結(jié)果

composer diagnose

然后逐個解決錯誤吧，首先是github fail 了，網(wǎng)上google 了下，發(fā)現(xiàn)需要設(shè)置一個token ,之前怎么不需要呢 ，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}" //替換成自己token }

token 生成在 https://github.com/settings/t…
執(zhí)行composer diagnose

搞定！
