How Can I Solve the Problem “Ubuntu 20.04 Pyenv Command Not Found”?

I am installing pyenv using this command:

git clone pyenv/pyenv-virtualenv ~/.pyenv/plugins/pyenv-virtualenv

Then

echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bashrc

When I give this command, an error appears

$ source ~/.bashrc

Command 'pyenv' not found, did you mean:

  command 'p7env' from deb libnss3-tools (2:3.49.1-1ubuntu1.5)
  command 'pyvenv' from deb python3-venv (3.8.2-0ubuntu2)

My commands are as follow:

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

sudo apt-get install libc6-dev gcc

sudo apt-get install -y make build-essential zlib1g-dev libssl-dev libsqlite3-dev libbz2-dev libreadline-dev wget curl llvm

git clone  ~/.pyenv/plugins/pyenv-virtualenv
