I cannot install gff3tool in a freshly created conda env (including python=2.7 and perl):

(gff3tool_env) [user@XXX]$ pip install gff3tool DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Hey @thierryjanssens I created a new virtual environment (myenv) using conda.
conda create --name myenv python=2.7 conda activate myenv

I tried to pip install gff3tool. Gff3tool seems to be successfully installed. Would you mind re-establishing a virtual environment? The following is my virtual environment variable for your reference. $ conda list myenv
