E: Unable to locate package cmake

I’m trying to deploy the app using streamlit sharing and the error logged on the main screen is:

ModuleNotFoundError: No module named 'dlib'

The error logged in the terminal is as follows:

  RuntimeError:

  *******************************************************************
   CMake must be installed to build the following extensions: _dlib_pybind11
  *******************************************************************

It looks like the error is due to the fact that cmake is not installed but I’ve included cmake in packages.txt and somehow it doesn’t recognize cmake as well as the other packages at all. Corresponding log is given below:

E: Unable to locate package freeglut3-dev
E: Unable to locate package libgtk2.0-dev
E: Couldn't find any package by glob 'libgtk2.0-dev
E: Couldn't find any package by regex 'libgtk2.0-dev
E: Unable to locate package cmake

Packages.txt file

Link to the hosted app on streamlit

I need to deploy it urgently. So any help is really appreciated.

Hi @Ashish013, welcome to the Streamlit community!

Your link to the packages.txt file doesn’t work, could you post the proper location?

Best,
Randy

Hey @randyzwitch sorry for the late response. I changed the requirements.txt by adding the packages altair, pandas to the start of the file as given in this example repo. And somehow it was able to read in the packages.txt properly this time. I can’t make sense sense of it but it has solved the problem for me. Thanks a lot for your immediate response.

Best,
Ashish M
