as mentioned in https://forums.fast.ai/t/htmlexporter-object-has-no-attribute-template-path/80775

That's because the Anaconda's default nbdev version is 0.2.40

' pip3 install -U nbdev' fixed that.

When I run 'pip3 install nbdev', it not worked on ubuntu20.04 under wsl2. So I install nbdev by install anaconda first, then use 'conda install -c fastai nbdev', it succeed. and then because of default nbdev version is 0.2.40 in conda, an error "'HTMLExporter' object has no attribute 'template_path'" occured. But 'pip3 install -U nbdev' fixed that.

Strongly suggest everyone should run 'pip3 install -U nbdev' after install nbdev by anaconda.
