libzymod-python

智眼Python SDK

单元测试

基于 test 文件夹中的 \\__init__.py -> load_tests 自动发现：

python -m unittest tests

安装SDK

从 pip 安装

pip install -U zymod

使用方法

使用

比如：

from zymod import upload

本地打包安装

打包

安装依赖包：

pip install -U setuptools wheel

运行：

rm -rf build/ dist/ zymod.egg-info/ && python setup.py bdist_wheel

在 dist 目录下会生成类似 zymod-1.0.0-py3-none-any.whl 的安装包。

本地安装

全局安装：

sudo pip install -U dist/zymod-*-py3-none-any.whl

用户目录安装：

pip install --user -U dist/zymod-*-py3-none-any.whl

卸载

pip uninstall zymod

上传至PyPI

配置文件

~/.pypirc

    pypi

password: 

安装上传工具

pip install -U twine

上传

twine upload dist/*

如果使用国内镜像源，需要等一两天国内服务器才会同步官方源。

可以临时指定官方源安装：

python3 -m pip install -i https://pypi.org/simple/ example-pkg
