pypi 安装后 pip 安装上的 importerror

Question

参考：https://github.com/louking/loutilities/tree/0.14.7

我在 pip 安装此包后收到导入错误。当我使用easy_install 的鸡蛋时，一切都很好。任何有关如何调试的帮助将不胜感激。

使用以下命令将此包安装到 pypi，并使用 "pip 18.1 from c:\users\lking\anaconda2\lib\site-packages\pip (python 2.7)"

进行 pip 安装

python setup.py install
python setup.py sdist bdist_wheel
twine upload dist/loutilities-0.14.7.*
   :
# later
pip install loutilities

当我运行这个项目，看下面

NoAppException: While importing "run", an ImportError was raised:

find_packages 似乎正在寻找合适的软件包：

Answer 1

在 pip install loutilities 之后，我在虚拟环境的 top-level 中看到一个未知目录 loutilities。该目录包含一些 *.pyc 但不包含任何子目录。我怀疑 import loutilities.flask_helpers 试图找到一个子目录 loutilities/flask_helpers 但失败了。

我认为top-level目录来自代码

        globit('loutilities', ['*.conf','*.pyc','*.pyd','*.dll','*.h','*.xlsx']),

我怀疑 globit() 中存在错误，将数据放在错误的目录中。
