我在Windows 64bit系统上使用Python 3.4.2。当我尝试使用pip安装sasl时，我收到错误def total_commission
commission = self.product&.consignor&.COMMISSION
if self.PRICE && commission
(self.PRICE * commission)
else
nil
end
end
error: INCLUDE environment variable is empty修改

和Microsoft Windows SDK for Windows 7 and .NET Framework 4后，它解决了上述问题。
现在我收到错误Microsoft Visual C++ 2010 Redistributable
Cannot open include file: 'sasl/sasl.h'有人知道如何解决这个问题吗？
