【问题描述】：

我对编程等还很陌生。我正在尝试使用 Spyder3，但我不断收到此错误（如下）。我使用的是 Geforce 1080ti，Ubuntu 18.04.01，python3.3.6，python2 没有安装。我试过 $ pip3 install keyring，它现在已经安装但仍然收到错误。

$ spyder3

【问题讨论】：

（这里是 Spyder 维护者）您说：“我对编程等还很陌生”。然后，请帮自己一个忙，下载并安装Anaconda，它是最新的 Spyder 附带的（不像最新的 Ubuntu，它现在有 10 个月大的版本），它非常容易安装，并且所有这些问题都得到了解决出来给你。顺便说一句，我们警告here 和here。

推荐 Anaconda 非常好，但它带来了很多需要学习的额外内容和大量自定义系统的默认 Python 环境的包袱。

【参考方案1】：

修复它：

pip3 install --upgrade keyrings.alt 

【讨论】：

你怎么知道的？

我在升级其版本后尝试使用pip3 时遇到了完全相同的错误。这个解决方案也为我解决了这个问题。

...为什么这是必要的？您找到更多信息了吗？

我需要为pip 而不是pip3 这样做。不过真的不明白为什么。
