Install Python latest version in Linux without sudo access

install-python-without-sudo.md

See this link before you really want to install pure Python by yourself instead of miniconda:

• https://gist.github.com/Hansimov/2d5d5985116039a0f2976dec91e8ed14

Method 1: (Recommend) Use Pyenv

• Note: If pyenv install <version> connect to python.org time out
  • Visit this secret gist to setup proxies: Hansimov/proxies.md

Download pyenv-installer and run it:

wget https://raw.githubusercontent.com/pyenv/pyenv-installer/master/bin/pyenv-installer
bash pyenv-installer

Add following lines to ~/.bashrc:

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
if command -v pyenv 1>/dev/null 2>&1; then
  eval "$(pyenv init -)"
fi

Relauch the shell to make it work:

bash # Or exec "$SHELL"

Then run the commands:

# Install the latest Python from source code
pyenv install 3.9.6
pyenv versions

# Switch Python version
pyenv global 3.9.6

# Check where Python is actually installed
pyenv prefix
# > /home/admin/.pyenv/versions/3.9.6

# Check the current Python version
python -V
# > Python 3.9.6

Method 2: (Backup) Use .tgz located in npmmirror

Visit following link to get latest Python

• https://registry.npmmirror.com/binary.html?path=python/
• Example: https://registry.npmmirror.com/-/binary/python/3.9.6/Python-3.9.6.tgz

Download the .tgz via Chrome browser and drag & drop to target path in server via MobaXterm.

tar -zxvf Python-3.9.6.tgz
# find ./Python-3.9.6/Python -type d | xargs chmod 0755
cd Python-3.11.3
./configure --prefix=$PWD/Python-3.9.6/Python
make
make install
mv ~/Python-3.9.6 ~/bin/

Add Python to path by adding this line to .bashrc:

export PATH=~/bin/Python-3.9.6:$PATH

or add alias to .bash_aliases:

alias python="~/bin/Python-3.9.6/python"

Do not forget to relauch bash to make the path work:

bash

If create Python venv,

python -m venv ~/bin/pyvenv

remove the above export and alias for root python, replace with the following ones:

# .bashrc
export PATH=~/bin/pyvenv/bin:$PATH
export pv=~/bin/pyvenv

# .bash_aliases
alias python="~/bin/pyvenv/bin/python"

bash

Activate python venv:

source $pv/bin/activate

or use alias:

alias sv="source ~/bin/pyvenv/bin/activate"
