Question

当我运行我的代码时，我收到以下错误ImportError: No module named ext

代码示例导致错误

import module.model
module.model.dropdb(input)
module.model.createdb(input)

追溯如下

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "module/models/__init__.py", line 54, in drop_db
    drop_db_with_migrations(quiet)
  File "module/models/__init__.py", line 31, in drop_db_with_migrations
    from module.app import db
  File "module/app.py", line 42, in <module>
    app.jinja_env.add_extension('hamlpy.ext.HamlPyExtension')
  File "/vagrant-dev/opt/dev_virtualenv/local/lib/python2.7/site-packages/Jinja2

您的问题出现在您的追溯中：

Traceback (most recent call last):
  -- SNIP --
  File "module/app.py", line 42, in <module>
    app.jinja_env.add_extension('hamlpy.ext.HamlPyExtension')
  -- SNIP --
ImportError: No module named ext

Jinja2使用dunder导入机制__import__（some_package_name_string）。它无法在您的ext包中找到子包hamlpy。

Python ImportError：没有名为ext的模块
