可攜性的步驟

setup.py 檔案

requirements.txt 檔案

可攜式套件結構

套件結構

requirements.txt 內容

在 work_dir/requirements.txt 作業

# Needed packages/versions
matplotlib
numpy==1.15.4
pycodestyle>=2.4.0

在 terminal 操作

datacamp@server:~$ pip install -r requirements.txt

setup.py 內容

from setuptools import setup

setup(name='my_package',
      version='0.0.1',
      description='An example package for DataCamp.',
      author='Adam Spannbauer',
      author_email='[email protected]',
      packages=['my_package'],
      install_requires=['matplotlib',
                        'numpy==1.15.4',
                        'pycodestyle>=2.4.0'])

install_requires 與 requirements.txt

在work_dir/requirements.txt 作業

# Specify where to install requirements from
--index-url https://pypi.python.org/simple/

# Needed packages/versions
matplotlib
numpy==1.15.4
pycodestyle>=2.4.0

文件： install_requires 與 requirements 檔案

用 pip 安裝你的套件

datacamp@server:~/work_dir $ pip install .

Building wheels for collected packages: my-package
  Running setup.py bdist_wheel for my-package ... done
Successfully built my-package
Installing collected packages: my-package
Successfully installed my-package-0.0.1
