Pyramid チュートリアルをやってみたメモ

Pyramidのことをもう少し知ろうと思い、チュートリアルをやってみました。つまづいた部分のメモです。

Prelude: Quick Project Startup with Scaffolds

手順通りにやったつもりだが、エラーになった。

原因は、virtualenvにインストールしたpyramid以外のものが使われていたこと。

% which pserve
/usr/local/bin/pserve

システムにインストールされていたpyramidをアンインストールし、virtualenvのものが使われるようになったら、上記のエラーは起きなくなりました。See also

% which pserve
