can't run "jb build lectures" code

[Joyshine-Qiu]

After download jupyter-book, I can't run "jb build lectures" code.

@Joyshine-Qiu it looks like your environment does not include sphinx-rediraffe package.

Are you using the quantecon environment setup with anaconda

conda env create -f environment.yml

which you can get from lecture-intro.zh-cn

Please let me know how you go.

Thank you, @mmcky ! I rebuilt the QuantEcon environment by deleting the environment and running "conda env create -f environment.yml" again, and now I successfully run "jb build lectures".
