Python 使用 setup.py 手動將 package 安裝到虛擬環境

Question

我正在使用 Python 3.7 進行開發。

我正在嘗試編寫一個小型 Python package 並將其安裝到虛擬環境中進行測試。 該庫的結構如下：

my_package/
    src/
        my_package/
            __init__.py
            utilities.py
            some_data_files/
    setup.py
    README.md
    ...

當我創建虛擬環境並嘗試安裝時：

(env) C:\Users\path\to\my_package python setup.py install

output 是：

running install
running bdist_egg
running egg_info
writing my_package.egg-info\PKG-INFO
writing dependency_links to my_package.egg-info\dependency_links.txt
writing top-level names to my_package.egg-info\top_level.txt
reading manifest file 'my_package.egg-info\SOURCES.txt'
reading manifest template 'MANIFEST.in'
writing manifest file 'my_package.egg-info\SOURCES.txt'
installing library code to build\bdist.win-amd64\egg

Copying my_package-0.0.1-py3.7.egg to c:\users\jon\development\my_package_env\env\lib\site-p

Adding my_package 0.0.1 to easy-install.pth file

Installed c:\users\jon\development\my_package_env\env\lib\site-packages\my_package-0.0.1-py3
.7.egg
Processing dependencies for my_package==0.0.1
Finished processing dependencies for my_package==0.0.1

site-packages中有一個 egg 文件，但沒有包含my_package目錄中任何文件的目錄。 這是我第一次編寫 Python package 進行分發，我正在使用Python 文檔作為指南，但我不想在任何地方上傳和測試。 有人可以告訴我必須采取哪些步驟才能在虛擬環境中本地測試我的 package 嗎？

• 使用以下命令創建項目的源代碼分發和構建分發：
  • (env) C:\Users\jon\development\my_package_env>python3 setup.py sdist
  • (env) C:\Users\jon\development\my_package_env>python3 setup.py bdist_wheel
• 注意dist/目錄中新創建的兩個檔案
• 嘗試在新的虛擬環境中安裝這些發行版：
  • C:\Users\jon\development\my_package_env>python3 -m venv sdist-env
  • C:\Users\jon\development\my_package_env>sdist-env\Scripts\activate.bat
  • (sdist-env) C:\Users\jon\development\my_package_env>pip install dist\my_package-0.0.1.tar.gz
  • (sdist-env) C:\Users\jon\development\my_package_env>deactivate
  • C:\Users\jon\development\my_package_env>python3 -m venv wheel-env
  • C:\Users\jon\development\my_package_env>wheel-env\Scripts\activate.bat
  • (wheel-env) C:\Users\jon\development\my_package_env>pip install dist\my_package-0.0.1-py3-none-any.whl
