brew遇到证书过期等问题

问题1

brew 安装软件的时候提示：

fatal: 无法访问 'https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git/'：SSL certificate problem: certificate has expired

临时解决

$ git config --global http.sslVerify false

问题2

brew 安装软件的时候提示：

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.

解决

$ echo insecure >> ~/.curlrc
$ export HOMEBREW_CURLRC=1

然后再安装
