檢視 Pyenv 的原始碼

'''pyenv'''是一套在使用者環境下管理多個不同[[Python]]版本的套件。

== 安裝 ==

先安裝系統需要的套件：

<syntaxhighlight lang="bash">
sudo apt install -y build-essential curl git libbz2-dev libcurl4-openssl-dev libffi-dev liblzma-dev libreadline-dev libsqlite3-dev libssl-dev libz-dev tk-dev; sudo apt clean
</syntaxhighlight>

接下來在自己的空間下安裝pyenv，然後安裝最新版的Python 3，並且更新pip：

<syntaxhighlight lang="bash">
git clone https://github.com/pyenv/pyenv.git ~/.pyenv; echo -e "export PYENV_ROOT=\"\${HOME}/.pyenv\"\nif [ -d \"\${PYENV_ROOT}\" ]; then\n    export PATH=\"\${PYENV_ROOT}/bin:\${PYENV_ROOT}/shims:\${PATH}\"\n    eval \"\$(pyenv init - --no-rehash)\"\nfi" >> ~/.profile; source ~/.profile; PY_VER=$(pyenv install -l | grep -o -P '^  3(\.\d+)+$' | sort -k 1,1 -k 2,2 -k 3,3 -n -t . | tail -n 1 | awk '{print $1}'); pyenv install ${PY_VER}; pyenv global ${PY_VER}; pip install -U pip; pip install -U poetry
</syntaxhighlight>

如果要裝Python 2的話（像是[[Trac]] 1.4），最後一個版本是2.7.18：

<syntaxhighlight lang="bash">
git clone https://github.com/pyenv/pyenv.git ~/.pyenv; echo -e "export PYENV_ROOT=\"\${HOME}/.pyenv\"\nif [ -d \"\${PYENV_ROOT}\" ]; then\n    export PATH=\"\${PYENV_ROOT}/bin:\${PYENV_ROOT}/shims:\${PATH}\"\n    eval \"\$(pyenv init - --no-rehash)\"\nfi" >> ~/.profile; source ~/.profile; export PY_VER=2.7.18; pyenv install ${PY_VER}; pyenv global ${PY_VER}; pip install -U pip; pip install -U poetry
</syntaxhighlight>

== 升級 ==

=== pyenv ===

<syntaxhighlight lang="bash">
cd ~/.pyenv; git pull -v
</syntaxhighlight>

=== Python ===

裝完新版後可以跑：

<syntaxhighlight lang="bash">
pyenv shell 3.9.13; pip install -U -r <(pyenv shell 3.9.1; pip freeze | sed 's/==.*//')
</syntaxhighlight>
