I'm running Python 3.10.9 in a conda environment with the Windows 10 OS. I'm trying to install the py-datatable package using pip, but I'm getting an error message. The pip install command successfully downloads the tarball from an internal mirror of pypi, but fails during build.

(env_python_2022_10) C:\Users\user1>pip --version
pip 22.3.1 from C:\Users\user1\.conda\envs\env_python_2022_10\lib\site-packages\pip (python 3.10)

(env_python_2022_10) C:\Users\user1>python --version

(env_python_2022_10) C:\Users\user1>conda --version
conda 4.8.3

  • try installing the dev version, the comments from [here](https://github.com/h2oai/datatable/issues/3305) seem to indicate that this works with the dev version. if it still fails, kindly visit the github issues page and leave a feedback for the team – sammywemmy Jul 10 '23 at 22:52
