在Ubuntu18中打开Spyder3时出现Keyring错误，缺少依赖项是原因吗？

Question

我在编程和相关方面还比较新。 我正在尝试使用Spyder3，但一直收到以下错误。 我使用的是Geforce 1080ti，Ubuntu 18.04.01，python3.3.6，未安装python2。 我尝试了$ pip3 install keyring，现在已安装，但仍然收到错误。

$ spyder3

（Spyder维护者在此) 你说：“我对编程和这方面还很新。”那么，请自己一个忙，下载并安装Anaconda，它带有最新的Spyder（不像最新的Ubuntu，它现在带有10个月前的版本），非常容易安装，并为您解决了所有这些问题。顺便说一下，我们在这里和这里警告过这个问题。 - Carlos Cordoba

推荐Anaconda固然好，但它附带了许多额外的东西需要学习，并且会对您系统的默认Python环境进行大量自定义设置。 - Fred Zimmerman

使用以下方法进行修复:

pip3 install --upgrade keyrings.alt

你是怎么知道的？ - shampoo

当我升级了 pip3 的版本后，我也遇到了完全相同的错误。这个解决方案对我也有效。 - natka_m

...而且为什么这是必要的？你找到更多信息了吗？ - exhuma

我需要为 pip 而不是 pip3 这样做。虽然不太理解为什么。 - gitaarik
