Django/Celery 找不到 importlib

Question

所以我刚刚将 django 更新到 1.2.3，现在当我尝试运行“python manage.py shell”以在 django 环境中工作时，出现以下错误。

Traceback (most recent call last):


File "manage.py", line 11, in <module>

    import importlib
ImportError: No module named importlib

任何想法。我似乎无法找到这里发生了什么，并且据我所知，我在网络服务器上运行相同的版本，并且没有出现相同的错误。

Answer 1

我相信 Python 2.7/3.1 中添加了 importlib 。您可以在此处下载 pyton 2.5 的端口：

• importlib 1.0.1 - Backport of importlib.import_module( ）来自 Python 2.7

另请检查 setup.cfg位于底部附近的芹菜，并确保满足所有其他要求（朝向脚本的底部）。

Answer 2

importlib 在 Python 3.1 版本中添加，然后向后移植到 Python 2.7。 PyPI 上提供第三方向后移植。

另请注意，“向后移植到 2.7”并不意味着 2.7 之后的所有版本都将具有 importlib。我相信 Python 3.0 没有 importlib。
