pip installation pybind11 issue

[slartz42]

Hello,

I'm hoping to use Ruckig for a project I'm working on but I can't seem to get it installed, I'm getting the following error below:

CMake Error at CMakeLists.txt:82 (find_package): By not providing "Findpybind11.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "pybind11", but CMake did not find one.

    Could not find a package configuration file provided by "pybind11"
    (requested version 2.6) with any of the following names:

      pybind11Config.cmake
      pybind11-config.cmake

    Add the installation prefix of "pybind11" to CMAKE_PREFIX_PATH or set
    "pybind11_DIR" to a directory containing one of the above files.  If
    "pybind11" provides a separate development package or SDK, be sure it has
    been installed.

I ran pip install pybind11 and it installed successfully, but I still get the error. I also ran pip install cmake which installed but did not fix the error.

I'm currently using a virtual environment in PyCharm, any help would be appreciated

First, you can also install Ruckig for Python via pip install ruckig.

If you need the latest version from the master branch, you can compile the Python package yourself. The easiest way to install the pybind11 dependency for that is to install it via a system-wide package manager (e.g. on ubuntu -> apt install pybind11-dev, on mac brew install pybind11). More info from pybind11 here and here.

Just to be clear, this error is related to using pip install ruckig , it does not seem to be working

Ah okay, I thought you were building the C++ project with cmake yourself and then only installing pybind11 with pip. That's why I gave some links to the pybind11 manual.

We provide pre-built Python packages for the major environments, and this issue might pop up when pip wants to build directly from source instead. I can see that setup.py might have difficulties in finding pybind11 in virtual environments. Nevertheless, installing pybind11 system-wide should solve this issue. Have you tried that as well?

Just out of interest:

• Which Python version?
• Which OS?
• Which CPU architecture?

[slartz42]

No problem, I probably should have chosen a different title.

• Python 3.11
• Windows 10
• 64 bit processor

We've now released v0.9.2 with a pre-built package for Python 3.11. Can you try again to run pip install ruckig?

That worked on the first try!! Thanks!
