Hi I've tried re-creating the virtual environment many times using python3 -m venv env/jupyter

but it keep showing this errors. My python (v3.6.5) in the venv runs fine.

xeus-python wheel version: 0.6.13

Any idea how to fix it? The xpython kernel on jupyter lab died after selected

Hi @JefferyLondon thanks for reporting this here!

FYI, the PyPI wheels are still experimental, and we recommend using a package manager, such as conda. We maintain conda-forge packages for xeus-python.

However, we are working really hard on improving the wheels story. The challenge is that xeus-python embeds Python and linux distributions patch python in all kinds of ways. We have a release coming up in the next few hours that fixes some of the issues, but will not yet enable virtual environments.

Hi Just confirming the version v0.7.0 still has the same issue.

SylvainCorlay commented 4 years ago

@JefferyLondon this should be fixed in the latest version (v0.7.1).
