今回さくらレンタルサーバにpythonを導入してみます。

スタンダードプラン以上だとSSHが利用可能なので、スタンダードプラン利用。

2023.07.31現在: さくらレンタルサーバの環境はFreeBSD13

$ uname -a
FreeBSD www1564.sakura.ne.jp 13.0-RELEASE-p12

git clone git://github.com/yyuu/pyenv.git ~/.pyenv

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
echo 'export TMPDIR="$HOME/tmp"' >> ~/.bash_profile

$ pyenv -v
pyenv 2.3.23-2-gac5efed3

Pythonのバージョン切り替えできるように、virtualenvインストール

git clone https://github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv

今回は3.3.4をインストール

CPPFLAGS="-I/usr/local/ssl/include" LDFLAGS="-L/usr/local/ssl/lib" pyenv install 3.3.4
pyenv virtualenv 3.3.4 flask_3.3.4
pyenv global flask_3.3.4
$ pyenv version
flask_3.3.4 (set by /home/hogehoge/.pyenv/version)

pip install --upgrade pip

pip install Flask

pip install numpy==1.9.3
pip install cython
pip install pandas==0.19.0
