Error installing cocoapods: cocoapods-core requires Ruby version >= 2.6. The current ruby version is 2.5.8.224.

Cocoapods 依赖 Ruby，Ruby 我是用 rvm 管理的，rvm 更新又遇到报错：Could not download rvm-installer, please report to https://github.com/rvm/rvm/issues。
使用 curl 又遇到报错：curl: (60) SSL certificate problem: certificate has expired。

问题最终也解决了，好事多磨吧！
遇到这类问题，不能急，需要耐心的按照它的报错信息去一步步解决就行！

$ curl -sSL https://get.rvm.io | bash -s stable
curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.
