ERROR: Could not build wheels for aeneas on ArchLinux

[Yasand123]

On ArchLinux, I got all the python packages (conda) and system packages. Since I'm on Arch I installed the corresponding system packages for Gradio with sudo pacman -S espeak-eg festival base-devel flac alsa-lib libsndfile vorbis-tools libxml2 libxslt zlib

However when I run pip install -r gradio_requirements.txt I get: ERROR: Could not build wheels for aeneas, which is required to install pyproject.toml-based projects.

Full output:

You need to install cannot find -lespeak the lib for espeak.

[tom2698]

I had the same issue. I did the following ( I'm on Fedora Linux ):

• sudo dnf install espeak
• sudo dnf install espeak-devel
• LIBRARY_PATH=/usr/lib64 pip install aeneas Then try install gradio requirements again. pip install -r gradio_requirements.txt
