Question

尝试使用make构建rabbitmq服务器时，我在codegen.py上遇到错误。我正在使用64位Windows 7，Python33，erl5.10.3，cygwin和GNU Make 4.0 for i686-pc-cygwin。我读到python中接受了三引号。我该如何解决这个问题？

D:\cygwin\bin\make
Makefile:378: deps.mk: No such file or directory
python codegen.py body ../rabbitmq-codegen//amqp-rabbitmq-0.9.1.json ../rabbitmq
-codegen//credit_extension.json src/rabbit_framing_amqp_0_9_1.erl
  File "codegen.py", line 110
    %%"""
        ^
SyntaxError: invalid syntax
Makefile:144: recipe for target 'src/rabbit_framing_amqp_0_9_1.erl' failed
make: *** [src/rabbit_framing_amqp_0_9_1.erl] Error 1

codegen.py，直到出现错误（最后一行代码）：

问题不在于三重引号。因为您使用的是Python 3，print是一个函数而不是语句。用括号中的三引号括起来。
