ebook-convert spits out python error? Can someone understand the error?

Question

I want to run ebook-convert together with Gitbook to produce my own pdf-files from my static files. When I just type ebook-convert I get this silly error message…

I installed

• a fresh version of python
• installed convert-ebook with NPM
• and Gitbook is running perfectly

Does anyone know what I could do?

Answer 1

I use my system python lib-dynload/_io.so replace with the

/Applications/calibre.app/Contents/Resources/Python/lib/python2.7/lib-dynload/_io.so

then it works, hope it can help you.

tks

Answer 2

I ran into the same problem and fixed it by updating Python from version 2.7.10 to 2.7.11.
