WSL error with Python 3.7

[dberardo-com]

i am trying to use crossenv in WSL to crosscompile the regex package for an openwrt, mipsel architecture.

i have downloaded the openwrt sdk and compiled python3-dev package inside it so as to have access to the python C header folder.

so i am now using:

crossenv staging_dir/hostpkg/bin/python3.7 cross_env --without-pip

to create the cross_env dir ... which works

but then i do

cd crosee_env/bin && activate

giving the error:

Traceback (most recent call last):
