python - 如何告诉 Pipenv 根据操作系统忽略 Pipfile 中的包

Question

我正在使用 Pipenv 创建一个 Python 项目，我有以下 Pipfile:

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]
black = "==19.10b0"
pylint = "==2.4.4"
pytest = "==5.3.1"
pytest-mock = "==1.13.0"
pytest-flask = "==0.15.0"

[packages]
python-decouple = "==3.3"
pytz = "*"
Flask = "==1.1.1"
Flask-RESTful = "==0.3.7"
uWSGI = "==2.0.18"

[requires]
python_version = "3.8"

我的问题是 uWSGI 包只适用于 Linux 而我使用的是 Windows。因此，每当我运行 pipenv install 时，它都会因此而失败。有没有办法告诉 Pipenv 仅在 Windows 环境中忽略此包的安装？

更新

这是命令的结果:pipenv lock -r

Pipfile.lock (e1b4e4) out of date, updating to (5696f6)…

Success!

Answer 1

除了版本，您还可以在 Pipenv 文件中传递环境/操作系统。

对于你的例子(只在 linux 上有 uWSGI):

uWSGI = {version = "*", sys_platform = "== 'linux'"}

您可以使用以下方法检查 sys_platform:

import sys
print(sys.platform) #python3

如果您有 sys 平台(例如 win32 或 linux)，您可以如上所述在 Pipenv 文件中添加 sys_platform

这应该可以解决您的问题

编辑:

uWSGI 目前有一个与 Windows 集成的问题:

Pipenv needs to run setup.py to inspect dependencies from a source distribution. You will need to ask uWSGI to release a wheel, or at least make setup.py egg_info work on Windows (the library itself does not need to work, only setup.py). from github.com/pypa/pipenv/issues/3084

使用此代码，您可以制定一个解决方法，我试过了并且有效:

# make pipenv lock uwsgi works under windows
# add func to os.py in virtualenv

def uname():
    import inspect
    caller = inspect.getmodule(inspect.stack()[1][0]).__name__
    if caller == 'uwsgiconfig':
        return ("", "", "", "", "")
    raise AttributeError()
