How to start a service with pyenv loading in linux?

Question

linux

If I write lines in interactive mode:

export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
pyenv activate nyaa
cd /home/nyaa
python run.py

then everything starts up and works...
If I add these lines to the .service file and run it, it gives an error:
pyenv: no such command `virtualenv-init'
and
pyenv: no such command `activate'

.service (I start in 1 line )

ExecStart=/bin/sh -c 'export PATH="$HOME/.pyenv/bin:$PATH" && eval "$(/root/.pyenv/bin/pyenv init -)" && eval "$(/root/.pyenv/bin/pyenv virtualenv-init -)" && /root/.pyenv/bin/pyenv activate nyaa && cd /home/nyaa && python run.py'

ExecStart=/bin/bash /root/script.sh
ls /root/script.sh cat
script.sh

#!/bin/bash
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
pyenv activate nyaa
cd /home/nyaa
python run.py
