If you are looking at this and feel too much chore to change Conda version packge=ver=py.* to pip style package==ver, I wrote this small script that delete the =py.* part from Conda style.

Note below code work on the presume that you already changed package=ver to package==ver.

#!/bin/bash

COUNT=0
find_pip=0

while IFS= read -r line; do
    COUNT=$(( $COUNT + 1 ))
#    echo "$COUNT"
#    echo "read it"
    if echo ${line} | grep -q -- "- pip:" ; then
#        echo "find it"
        find_pip=1
        indent=`awk -F- '{print length($1)}' <<< "$line"`
        pip_indent=$(( $indent + 2 ))
#        echo $indent
#    echo $pip_indent
    fi

    line_indent=`awk -F- '{print length($1)}' <<< "$line"`

    if [[ ${find_pip} ]] && [[ ${pip_indent} -eq ${line_indent} ]]; then
#        echo "$line"
        new_line=`echo ${line} | cut -d'=' -f-3`
        new_line="    $new_line"
#        echo "${new_line}"
        sed -e "${COUNT}s/.*/${new_line}/" -i '' $1
    fi
done < "$1"
