porechop installation error

[saassli21]

I can't install porechop using conda
I already have my conda env activated but when I run : conda install -c bioconda porechop I have this error :

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
