Hi all, Trying to get PyMuPDF running in a TrueNAS / FreeBSD jail. When executing python -m pip install --upgrade pymupdf I get the following:
Doing some googling, this seemed to be an issue with mupdf not being installed. So, I tried that by executing python -m pip install --upgrade mupdf which returns "error: metadata-generation-failed". I'm using python 3.7. Thoughts on what might be happening here? Thanks! |

Could you say what version of PyMuPDF pip was trying to install, e.g. post the full output? Your error looks like what one might see when compiling a 1.19.x release, not the current 1.20.1 release. (I'm not sure why your simple pip command would be trying to install an old release like that though.) 1.20.x sdist already contains mupdf, so there should be no problem with finding mupdf's |

Apologies, after having seen the log recently mentioned in #1563, i think i have a better understanding about how things can go wrong in the way you describe, when building 1.20.x from source. It looks like a workaround may be to do Could you try that and report back? |

Thanks for testing. This is a failure to build mupdf; the mupdf build scripts unfortunately hard-code the use of bash, so there's no way round this other than to install it on your machine before building PyMuPDF. |

I should have seen that, honestly. Sorry for that as it's pretty obvious. Making progress, but now what I set is an error on what appears to be truetype assets? |

No problem at all. Is the new error while building mupdf, or later on when building pymupdf? Could you post the full output if you still have it? |

Thanks for the output. I think the problem might be caused by empty output files left behind from the failed attempt to run [For example the output is not showing generation of So we need to do a clean build of mupdf. This is probably best done by simply removing the whole [Setting |

Success! I cleaned everything up like you said and reran the build. Ended up getting this:
So, I ran pip install harfbuzz and reran setup, and voila! looks like I have a successful build! |
