setuptools 和 pip:选择最小安装和完整安装 [英] setuptools and pip: choice of minimal and complete install

问题描述

我们创建了一个依赖于其他库的库.但是有必要的(例如对于服务器批处理)和可选的依赖项(例如对于具有 GUI 的客户端).

We've made a library which depends on other libraries. But there are necessary (e.g. for server batch processing) and optional dependencies (e.g. for clients with GUI).

这样的事情可能吗:

pip install mylib.tar.gz  # automatically downloads and installs with the minimal set of dependencies

pip install mylib.tar.gz  --install-option="complete"  # automatically installs with all dependencies

我找到了 extra_require 标志，但我如何告诉 pip 使用它们?setup.py 看起来像这样:

I've found the extra_require flag, but how can I tell pip to use them? The setup.py looks like this:

from setuptools import setup

# ...

# Hard library depencencies:
requires = [
    "numpy>=1.4.1",
    "scipy>=0.7.2",
    "traits>=3.4.0"
]

# Soft library dependencies:
recommended = {
    "mpl": ["matplotlib>=0.99.3"],
    "bn": ["bottleneck>=0.6"]
}

# ...

# Installer parameters:
setup(
    name = "mylib",
    #...
    install_requires = requires,
    extras_require = recommended
)

推荐答案

您可以在 extras_require 中安装包，方法是在方括号中附加推荐依赖项的名称(即 [mpl] 或 [bn] 在你的情况下)到 pip 中的包名称.

You can install the packages in extras_require by appending the name of the recommended dependency in square brackets (i.e. [mpl] or [bn] in your case) to the package name in pip.

因此要安装具有附加要求的mylib"，您可以像这样调用 pip:

So to install 'mylib' with the additional requirements, you would call pip like this:

pip install 'mylib[mpl]'
pip install 'mylib[bn]'

这将首先下载并安装额外的依赖项，然后是mylib 的核心依赖项.

This will first download and install the extra dependencies, and then mylib's core dependencies.

这与您使用 setuptools 声明这些依赖项的方式类似:http://pythonhosted.org/setuptools/setuptools.html#declaring-extras-optional-features-with-their-own-dependencies(请参阅第三个示例中的 install_requires 值)

This is anologous to how you declare those dependencies with setuptools: http://pythonhosted.org/setuptools/setuptools.html#declaring-extras-optional-features-with-their-own-dependencies (see the install_requires value in the third example)
