错误：给出了双重要求：枕头== 6.1.0（来自-r requirements.txt（第25行））

Question

我正在使用源代码https://github.com/odoo/odoo/tree/aa0554d224337e1d966479a351a3ed059d297765

在Windows 10（Python版）上

Python 3.8.0 (tags/v3.8.0:fa919fd, Oct 14 2019, 19:21:23) [MSC v.1916 32 bit (Intel)] on win32

我发现错误

e:\source_code\github.com\xxxxxxx\odoo>pip install -r requirements.txt
Ignoring gevent: markers 'sys_platform != "win32" and python_version < "3.7"' don't match your environment
Ignoring gevent: markers 'sys_platform != "win32" and python_version >= "3.7"' don't match your environment

e:\source_code\github.com\xxxxxxx\odoo>

如何解决？

Answer 1

这看起来像是Odoo源代码中的错误：

public void utilMethod(IntStream range, List<Double> values) {
   range.forEach(i->i);
 }

如果第二行中的条件为true，则显然会导致双重要求。

我建议将其修补为：

IntStream.iterate(0, i->i<10, i->i+1).forEach(System.out::println);

IntStream.iterate(10, i->i>0, i->i-1).forEach(System.out::println);

应该 在所有操作系统和Python版本上都能正常工作。

Answer 2

我只是摆脱了第24行，而离开了第25行，因为它似乎对此感到满意。

###Pillow==5.4.1
Pillow==6.1.0 ; sys_platform == 'win32' and python_version >= '3.7'

编辑：我改变了主意。如果两者都喜欢，最好使用较新的版本...
