sphinx无法找到sphinx_rtd_theme

Question

I'm newbe of Sphinx,

I tried to use html_theme = 'sphinx_rtd_theme' in conf.py

but I get message below when I run "make html" :

sphinx_rtd_theme is no longer a hard dependency since version 1.4.0. Please install it manually.(pip install sphinx_rtd_theme)

I already installed it with pip install sphinx_rtd_them
(part of pip list)

Package Version

---

alabaster 0.7.11
sphinx-rtd-theme 0.4.1
Sphinx 1.8.1

Also I installed sphinx-doc with brew.

Anybody with same issue??

Another things to know is...My ubuntu PC works perfectly,
but not works on Macbook pro...

Answer 1

Ok...WTF...I have no idea how it works, But I ran

brew remove sphinx-doc

and "make html" worked,

If anyone can answer why and how this happened, please let me know...
