我在"；源"；文件夹，并使用CCD_ 1命令重建HTML。一切正常，我将文件夹同步到GitHub。然而，当我在Read the Docs网站上重建文档时，我在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复了一些拼写错误，仅此而已。为什么会出现此错误并且生成失败？谢谢

我在iPython笔记本电脑上遇到了这个问题，因为我有一个旧版本的Pygments。使用升级Pygments
pip3 install --upgrade Pygments
我也遭受了同样的痛苦。在我的情况下，由于beacause，我将笔记本更新为最新版本，并将conda本身保留为非常旧的版本，因此它可能会引起问题，但当我运行代码：pip3 install Pygments==2.6.1时，它对我来说非常好
这似乎与正在使用的Pygments版本有关(有关详细信息，请参阅本期GitHub(，该版本需要大于2.4.1。
在我的案例中，通过要求ReadTheDocs使用Pygments==2.6.1解决了这个问题
我也面临同样的问题。对我来说，这是通过以下步骤解决的：Python命令失败，断言错误：错误的颜色格式，基本上是通过安装nbconvert==6.0.0rc0。感谢
