Question

我正在尝试在Ubuntu 16.10上从源代码安装Python 3.6。

make test

当我进行测试时，安装会引发错误说..

问题是什么？

Answer 1

您指定的此代码似乎不存在于上一个或更新的分支上。

然而，此特定错误表明CA不是有效（可信）CA.

检查特定代码，似乎密钥是lib / test文件夹中的keycert3.pem。

CA文件是pycacert.pem，您可以将此CA添加到您的计算机信任。您可以在超级用户上查看答案，例如https://superuser.com/questions/437330/how-do-you-add-a-certificate-authority-ca-to-ubuntu

指定如何操作虽然我似乎记得只是将文件复制到/ etc / ssl / certs就足够了。希望它有所帮助。

首先，从其官方网站安装Python 3.6：

cd /opt sudo wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz 然后打开包装

sudo tar -xvf Python-3.6.3.tgz

这应该为您工作！

（安装Python 3.6.1）SSLError：SSL：TLSV1_ALERT_UNKNOWN_CA tlsv1 alert unknown ca
