在 Vagrant Ubuntu 20.04 VM 上安装 pyenv

Question

我正在尝试在我的 vagrant 虚拟机上安装 pyenv。

我的 Vagrantfile 看起来像这样：

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/focal64"
  config.vm.box_version = "20220517.0.0"

  config.vm.provision :shell, path: "./provision/install-pyenv.sh", privileged: false
  config.vm.provision :shell, path: "./provision/install-python.sh", privileged: false
end

其中 ./provision/install-pyenv.sh 是：

#!/usr/bin/env bash

# Install required dependencies
sudo apt-get install -y make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev \
libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl

# Run the installer
curl https://pyenv.run | bash

# Add the required variables to the ~/.bashrc file
echo 'export PATH="$HOME/.pyenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bashrc
source ~/.bashrc

而./provision/install-python.sh是：

#!/usr/bin/env bash

# Install the required Python version
pyenv install -v 3.10.4

# Set the global python version
pyenv global 3.10.4

但是当我运行 vagrant up - 我得到以下错误：

pyenv 不是可识别的命令。我究竟做错了什么？我是否将环境变量添加到不正确的 ~/.bashrc 中？

我真的不明白我哪里错了。

似乎实现此目的的最佳方法是以特权用户身份安装依赖项。

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/focal64"
  config.vm.box_version = "20220517.0.0"

  # Python
  config.vm.provision :shell, path: "./provision/install-pyenv-dependencies.sh"
  config.vm.provision :shell, privileged: false, path: "./provision/install-python.sh"

end

其中 install-pyenv-dependencies.sh 是：

#!/usr/bin/env bash

# Install required dependencies
apt-get update

apt-get install -y make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev \
libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl --fix-missing

而install-python.sh，是：

#!/usr/bin/env bash

# Run the installer
curl -L https://raw.githubusercontent.com/pyenv/pyenv-installer/master/bin/pyenv-installer | bash

# Update the bashrc file
cat >> ~/.bashrc <<'EOL'
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
EOL

# Export the env vars
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"

# Use pyenv to install Python
pyenv install -v 3.10.4
pyenv global 3.10.4
