我正在尝试安装一些食谱，但是遇到某种身份验证问题。当我做
conan install eigen/3.3.7@conan/stable
我收到以下错误

我的遥控器如下：

[conan user的输出如下

因此，如果我正确地通过了柯南社区的身份验证，为什么在尝试安装配方时出现权限定义错误。另外，尽管安装配方我不需要进行身份验证，所以这里发生了什么？
编辑：我也尝试过在没有身份验证的情况下安装配方，但是在那种情况下，它只要求输入用户名/密码。如果我尝试使用Bintray用户名和密码，它将拒绝它们。

我在Ubuntu 18.04上于2020年遇到此问题，并能够通过以下终端命令升级到Conan 1.20.2来解决此问题：
sudo -H pip3 uninstall conan
sudo -H pip3 install conan==1.20.2
