Python - 在 setup.py install 之前和之后导入包模块 [英] Python - Import package modules before as well as after setup.py install

问题描述

假设一个 Python 包(例如，MyPackage)由几个模块(例如，MyModule1.py 和 MyModule2.py)和一组单元测试(例如，在 MyPackage_test.py 中).

<预><代码>.├── 我的包裹│ ├── __init__.py│ ├── MyModule1.py│ └── MyModule2.py├── README.md├──需求.txt├── setup.py└── 测试└── MyPackage_test.py

我想在MyPackage_test.py 的单元测试中导入MyModule1.py 的函数.具体来说，我想通过 setup.py install MyPackage 在包安装之前和之后导入这些函数.

目前，我使用两个单独的命令，具体取决于安装包之前或之后的状态:

# BEFORE导入系统，操作系统sys.path.append(os.path.join(os.path.dirname(__file__), '..', 'MyPackage'))# 后导入我的包裹

这可以用一个命令完成吗?

解决方案

选项 1:

似乎以下命令满足了我的需要:

sys.path.append(os.path.join(__file__.split(__info__)[0] + __info__), __info__)

选项 2:

根据 __init__.py 的位置，这也有效:

sys.path.append(os.path.dirname(os.path.split(inspect.getfile(MyPackage))[0]))

选项 3:

此外，ResourceManager API 似乎提供了其他方法.

Assume a Python package (e.g., MyPackage) that consists of several modules (e.g., MyModule1.py and MyModule2.py) and a set of unittests (e.g., in MyPackage_test.py).

.
├── MyPackage
│   ├── __init__.py
│   ├── MyModule1.py
│   └── MyModule2.py
├── README.md
├── requirements.txt
├── setup.py
└── tests
    └── MyPackage_test.py

I would like to import functions of MyModule1.py within the unittests of MyPackage_test.py. Specifically, I would like to import the functions both before as well as after package installation via setup.py install MyPackage.

Currently, I am using two separate commands, depending on the state before or after package installation:

# BEFORE
import sys, os
sys.path.append(os.path.join(os.path.dirname(__file__), '..', 'MyPackage'))

# AFTER
import MyPackage

Can this be done with a single command?

解决方案

Option 1:

It seems that the following command does what I need:

sys.path.append(os.path.join(__file__.split(__info__)[0] + __info__), __info__)

Option 2:

Depending on the location of __init__.py, this also works:

sys.path.append(os.path.dirname(os.path.split(inspect.getfile(MyPackage))[0]))

Option 3:

Moreover, the ResourceManager API seems to offer additional methods.
