Google AppEngine プロジェクトで reportlab を使用していますが、dev_appserver で動作させることができません。問題なく本番環境で問題なく動作します。Reportlab を 2.5.5 ソースのディレクトリ全体としてプロジェクトに配置しました。以前にこの同じ問題を報告した zip バージョンは使用していません。

最初は問題なく動作しているように見えますが、その後は毎回問題があるようです。すべてをシャットダウンしてpycファイルを消去しようとしましたが、問題が解決しないようですが、Reportlabディレクトリ全体を削除してソースから再コピーすると、1回は機能し、二度と機能しなくなります。

Python 2.7 と NDB で最新の SDK(1.6.6) と最新の Reportlab(2.5) を使用しています。私の dev_appserver は Mac osX Lion で実行されています

これが私が得ているトレースバックです。

reportlab 2.5コードを見ると、lib / utils.pyの463〜468行目です。

def rl_isdir(pn,os_path_isdir=os.path.isdir,os_path_normpath=os.path.normpath):
    if os_path_isdir(pn): return True
    if _isFSD or __loader__ is None: return False
    pn = _startswith_rl(os_path_normpath(pn))
    if not pn.endswith(os.sep): pn += os.sep
    return len(filter(lambda x,pn=pn: x.startswith(pn),__loader__._files.keys()))>0

そのutilsファイルには魔法があるようで、このメソッドではローダーの内部構造に関する仮定があります。HardenedModulesHook（サンドボックスのエミュレートに使用）には_files属性がないため、SDKで失敗します。

本番環境で機能rl_isdirするため、最後の行より前の行のいずれかでTrueまたはFalseを返す場合があります。そうでない場合は、__loader__外観が異なる場合があります。

utils.pyとにかくアプリケーションディレクトリに含まれているファイルを変更することをお勧めします。おそらく、468行目を。に置き換えてくださいreturn False。
