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.

这对我很有用。我打开cmd行并运行以下命令。又拉了一下。

Git配置——global http。sslVerify假

下载并安装本地证书。它可能在你的公司网站上发布。例如，*。cer文件。

右键单击它并选择安装证书。将出现“证书导入向导”。选择本地机器。按Next，确认。 选择“将所有证书放入以下存储区”，按“浏览”并选择“受信任的根证书颁发机构”，“确定”，“完成”。

此外，您还可以检查其他应用程序是否可以获取、拉取或推送数据。例如，在Android Studio或IDEA中，你应该在设置中选择这个复选框:使用凭证帮助。

在运行composer update/install之前使用此命令:

git config --global http.sslverify false

在我的例子中，因为我已经为windows 7安装了ConEmu终端，它在C:\Program Files\Git\mingw64\ssl\certs.的安装过程中创建了ca-bundle

因此，我必须在终端上运行以下命令才能使其工作:

$ git config --global http.sslbackend schannel
$ git config --global http.sslcainfo /mingw64/ssl/certs/ca-bundle.crt

因此，我的C:\Program Files\Git\etc\gitconfig包含以下内容:

[http]
    sslBackend = schannel
    sslCAinfo = /mingw64/ssl/certs/ca-bundle.crt

另外，在安装Git时，我选择了与这里提到的相同的选项。

希望有帮助!

当我试图“克隆”项目时，我得到了这个错误。一个解决办法是只使用网页上的“下载压缩文件”，这对我来说，实现了我想做的事情。
