Python-3.8 (in Linux) Installation Problem

[Mahedi-61]

It's not a good idea to uninstall Python-2.7.
Because, it may cause dependency issues since many applications in the Linux system inherently depend on Python-2.7.

Try to install Python-3.8 as a separate application. You can do the following

wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz && tar -xvf Python-3.8.0.tgz
cd Python-3.8.0
./configure
make
sudo make altinstall

After installation, type python3.8 on the terminal.
Let me know whether it works or not.

You can aslo make it python3 by making an alias variable in the ~/.bashrc file. try

sudo nano ~/.bashrc
alias python3="python3.8"

Then press Ctrl+O + Ctrl+M + Ctrl+X

Thank you sir. It works. I have installed it. But after that I loss pip... I have seen many youtube videos. but I can't find pip3 even no longer pip is there in pc

First, try typing in terminal pip3.8

If it's not there then try this
sudo apt-get install python3-pip
Then again, try typing in terminal pip3.8

If that doesn't work. then try this.

wget https://bootstrap.pypa.io/get-pip.py
python3.8 get-pip.py

If that run properly, then instead of pip3 you have to use every time python3.8 -m pip
And of course, sudo at the first

For example, if you want to install TensorFlow, try

sudo python3.8 -m pip install tensorflow==1.4.0
sudo python3.8 -m pip install  keras

Sir.. thanks... but not working for me.. It seems like 'zlib' library is not there. I also try to work with virtualenv ... but that also required 'zlib' library... But it's not in python3.8 ... I check that through import zlib ...but doesn't work.... but python 2.7 and even 3.6 have that library... don't understand what to do nowww

[Mahedi-61]

sudo apt-get install libgcrypt11-dev zlib1g-dev
