Question

当我使用＆＃34; pip install＆＃34;要在Windows上安装scrapy for Python，我请求反馈：

Exception:
Traceback (most recent call last):
  File "c:\users\limin\appdata\local\programs\python\python36\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 30: invalid start byte

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "c:\users\limin\appdata\local\programs\python\python36\lib\site-packages\pip\basecommand.py", line 215, in main
    status = self.run(options, args)

  File "c:\users\limin\appdata\local\programs\python\python36\lib\site-packages\pip\compat\__init__.py", line 75, in console_to_str
    return s.decode('utf_8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb6 in position 30: invalid start byte

我知道这可能是一个编码问题，但我不知道如何解决它。谁能帮我？感谢。

Scrapy在Python 2.7和Python 3.3或更高版本上运行（在Windows上不支持Python 3）。

很抱歉成为坏消息的承担者。如果您特别擅长使用Python 3.6，那么在Scrapy文档中也可以使用Anaconda。或者如果紧急，您可以使用Python 2.7和extension NSImage { func resized(to newSize: NSSize) -> NSImage? { if let bitmapRep = NSBitmapImageRep( bitmapDataPlanes: nil, pixelsWide: Int(newSize.width), pixelsHigh: Int(newSize.height), bitsPerSample: 8, samplesPerPixel: 4, hasAlpha: true, isPlanar: false, colorSpaceName: .calibratedRGB, bytesPerRow: 0, bitsPerPixel: 0 ) { bitmapRep.size = newSize NSGraphicsContext.saveGraphicsState() NSGraphicsContext.current = NSGraphicsContext(bitmapImageRep: bitmapRep) draw(in: NSRect(x: 0, y: 0, width: newSize.width, height: newSize.height), from: .zero, operation: .copy, fraction: 1.0) NSGraphicsContext.restoreGraphicsState() let resizedImage = NSImage(size: newSize) resizedImage.addRepresentation(bitmapRep) return resizedImage } return nil } } let targetSize = NSSize(width: 256.0, height: 256.0) let newImageResized = myimage.resized(to: targetSize)。根据我的经验，Python 2.7在Scrapy中运行得更好。

无法安装Scrapy / Twisted
