运行以下命令后，我在OSX Yosemite上出现卷曲错误。我可以在其他人使用brew但不能用于php56。我可以从https://www.php.net/get/php-5.6.10.tar.bz2/from/this/mirror下载，但不能通过curl下载。我该如何解决这个问题？
brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php
brew options php56
brew install --with-cgi php56
==> Installing php56 from homebrew/homebrew-php
==> Downloading https://www.php.net/get/php-5.6.10.tar.bz2/from/this/mirror
curl: (60) SSL certificate problem: Invalid certificate chain
More details here: http://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.

答案 0 :(得分：1)
我最终做的是暂时disabling certificate verification for all curl requests
echo insecure >> ~/.curlrc
然后运行我信任的brew install，然后......
不要忘记最后回到安全状态（delete the last line from ~./curlrc）。
