Setup python 3.6 enviroment with virtualenv

My wife ask me to convert few of PDF files to Excell spreadsheet. I did same thing last year by creating some small scripting program in python to do the conversion, but I don’t know where I put my code right now. Maybe lost during formating my laptop last year..haha

I am 懒 right now (guess what I wrote in hànzì) and I don’t remember how I did last time. Hahaha.. With my Google-fu skill, I found out DfTables offer free API for converting document to another format. Nice!

Fedora 30 comes with python 3.7 installed. Sadly, dftables.com API doesn’t currently work on 3.7 but no worries since we can create virtualenv to load Python 3.6

Now let install the virtualenv into our workstation, take note I don’t use sudo since my account have administration access, so load with --user args should be enough. I don’t like run something and everthing with sudo.

$ pip3 install --user virtualenv

Download python 3.6 with DNF

$ sudo dnf install python36

Create some directory and cd to that directory. For example I am using ~/workstation/PDF-to-Excell. We will use python 3.6 to install the new python environment:

$ cd ~/workstation/PDF-to-Excell
$ virtualenv --python=/usr/bin/python3.6 python36

now step into the environment using

$ source python36/bin/activate

you should get something like this:

(python36) [rnm@robbinespu PDF-to-Excell] $ python --version
Python 3.6.9

Now let try install DfTables pips

(python36) [rnm@robbinespu PDF-to-Excell] $ pip install git+https://github.com/pdftables/python-pdftables-api.git

It working, nice! Currently, We have isolated python 3.6 virtual enviroment and successfully installing required pips for Pdftables dependencies and now, let have some fun
