If you get an error such as command not found, install it using your OS’s standard package manager.
- For Debian-based OSes (such as Ubuntu)
```
sudo apt update
sudo apt upgrade -y
sudo apt install git
```
- For Red Hat-based OSes (such as Fedora)
```
sudo yum install git
```
```
sudo dnf install git
```
Enter the following command. If the version is displayed, the installation was successful. (If it does not appear, restart the terminal.)
```
git --version
```

2. Pythonのインストール#

Open a terminal and run the following command. Also make sure the version is 3.13 or later.

If you get an error such as command not found or the version is too low, install Python using pyenv, a Python version management tool.

Warning

The installation instructions may not always be up to date, so refer to pyenv/pyenv.

Run the following command.
```
curl https://pyenv.run | bash
```
Next, run the following command to check which shell you are using.
```
echo $SHELL
```

Run the commands according to the shell that is displayed.

If bash is displayed, run the following commands.

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.profile
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.profile

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(pyenv init -)"' >> ~/.bash_profile

If zsh is displayed, run the following commands.

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
