Phonopy and phono3py have been successfully installed. But installing Phonopy-spectroscopy on the installation website, we encountered problems.

and I also tried to the command _pip install spectrumutils[iplot] , but it does not work

Apologies - the installation instructions have a small mistake. The PATH and PYTHONPATH should be set to e.g.:

PATH=${PATH}:/Volumes/Data/Repositories/Phonopy-Spectroscopy/scripts PYTHONPATH=${PYTHONPATH}:/Volumes/Data/Repositories/Phonopy-Spectroscopy/lib

Could you try this and let me know whether it fixes the problem?

[JMSkelton]

Further to my previous message, I have now updated the installation instructions in the documentation.

I will close this issue now - but please reopen it if the new instructions do not fix your problem.
