我试着跟随，它工作✅

git config --global http.sslVerify false

You might have a DNS issue and not a certificate issue, so before you disable SSL verification in your Git shell you should rule out a DNS problem. Cases such as these have been mentioned in Q&A forums such as https-issues-possibly-related-to-dns. If you are using WSL on Windows as your terminal, then you can try running sudo echo nameserver 8.8.8.8 > /etc/resolv.conf and then issue the git commands to see if that makes a difference. This does not seem to be a permanent DNS fix (lasting only the lifetime of your terminal session), but it could help you determine whether it is a DNS issue and not a certificate issue. You could also check this document on configuring your network to use a public DNS. Again, this is only to help you determine if your DNS settings might need adjusting in order to help resolve the certificate issues.

在运行composer update/install之前使用此命令:

git config --global http.sslverify false

如果要完全禁用SSL验证，则打开Git Bash并运行该命令。

git config --global http.sslVerify false

注意:此解决方案使您容易受到中间人攻击等攻击。 因此，尽快再次开启验证:

git config --global http.sslVerify true

我也遇到过这个问题。最终在MSDN博客的指导下得到了解决。

更新

实际上，你需要在git的证书文件curl-ca-bundel中添加证书。位于Git\bin目录下。

步骤

Open your github page in browser, and click over lock icon in address bar. In the opened little popup up navigate to 'view certificate' link, it will open a popup window. In which navigate to certificates tab (3rd in my case). Select the top node that is root certificate. And press copy certificate button in the bottom and save the file. In file explorer navigate Git\bin directory and open curl-ca-bundle.crt in text editor. Open the exported certificate file (in step 3) in text editor as well. Copy all of the content from exported certificate to the end of curl-ca-bundle.crt, and save.

最后检查状态。请注意备份curl-ca-bundle。CRT文件之前编辑，以保持安全。

我在使用visual studio时出现了这个错误。当您在Visual Studio选项窗口中将加密网络提供程序设置设置为OpenSSL时，就会发生这种情况。当我将设置更改为安全通道时，它为我解决了这个问题。这个设置一定是在我升级我的VS时为我设置的。
