I already referred to this related post

I am currently using a jupyter notebook in my server (where I don't have sudo access) which has python 2.7 kernel.

However, I would like to add Python >= 3.5 as the kernel. So, I was using followed the tutorial to install Pyenv.

The installation is successful and I get the below message in my jupyter notebook

WARNING: seems you still have not added 'pyenv' to the load path.

# Load pyenv automatically by adding
# the following to ~/.bashrc:

export PATH="/home/abcd/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

Later, when I try to execute the below command, I get an error as shown below

!pyenv install --list | grep " 3\.[678]"

Please note that I am using ! symbol as I am executing it from Jupyter notebook cell

/bin/sh: 1: pyenv: not found

How can I avoid this error and make pyenv work and produce the below output

jupyter pyenv jupyter-notebook virtualenv python

As per the discussion in comments section, it turns out the pyenv path wasn't exported to .bashrc. It can be done by executing the following commands in terminal:

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bashrc

then restart the shell

exec "$SHELL"

Now, you can use pyenv to create virtual environments, then activate the environment and start working without interfering with the system environment.
