I'm trying to install homebrew

$ ruby -e "$(curl -fsSL"

is returning the following curl certificate error:

curl: (60) SSL certificate problem: unable to get local issuer certificate More details here:

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"
