Install Homebrew Issue with Curl SSL certificate problem

January 22, 2015

I’m trying to install homebrew

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

is returning the following curl certificate error:

curl: (60) SSL certificate problem: unable to get local issuer certificate
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.

as mentioned on bottom of error log, you could install in unsafe ssl using ” -k “
. So you should try with:

$ ruby -e "$(curl -k -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
