[graalvm-users] Build stop of pandas with graalpython

[Tim Felgentreff]

Hi,

it looks like you didn't create a venv.

Can you try to create a venv first and report back?

The steps you should run are:

$GRAALVM_HOME/graalpython -m venv pandas_venv
source pandas_venv/bin/activate
python -m ginstall install pandas

Best,
Tim


Hi,

I am following the website docs for the test of graalpython
https://www.graalvm.org/reference-manual/python/

The installation of pandas seems to stop without an error.

— Would appreciate some advice on how I can possibly fix this.

Best,
Marius
