问题描述
我在“源”文件夹中进行了一些最小的更新，并使用make html命令重建了HTML。一切正常，我将文件夹同步到GitHub。但是，当我在“阅读文档”网站上重建文档时，在cat source/conf.py之后出现了这样的错误：
AssertionError: wrong color format 'var(--jp-mirror-editor-variable-color)'
我只是在文档中添加了一些文本并修正了一些错字，仅此而已。为什么会发生此错误而构建失败？谢谢。

解决方法
这似乎与一个人使用的Pygments版本有关（有关详细信息，请参见此GitHub issue），该版本必须大于2.4.1。
就我而言，该问题已通过要求ReadTheDocs使用：Pygments==2.6.1
我也遇到了同样的问题。在我的情况下，由于笔记本电脑升起，我将笔记本电脑更新到最新版本，并将康达本身留给了一个很旧的笔记本电脑，因此可能会引起问题，但我运行了代码：{ {1}}对我来说很好用
,我面临着同样的问题。对我来说，这可以通过遵循Python command fails with AssertionError: wrong color format中的步骤（基本上是通过安装nbconvert==6.0.0rc0）来解决。谢谢
我在使用 iPython 笔记本时遇到了这个问题，因为我有一个旧版本的 Pygments。使用
升级 Pygmentspip3 install --upgrade Pygments
