Homebrew安装gcc：curl: (60) SSL certificate problem: certificate has expired

Posted 2021-12-11 bitcarmanlee

1.出现的问题

macos上执行安装gcc命令：

rew install gcc --without-multilib

出现如下情况

curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
Error: Failed to download resource "mpfr"
Download failed: https://ftp.gnu.org/gnu/mpfr/mpfr-3.1.4.tar.xz

2.解决方式

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

然后重新执行命令即可。

有可能是Homebrew长期没有更新，导致本地证书过期。
