在Windows上安装python-midi软件包时出错

Question

I was trying to install some packages for python on Windows using pip and got the following error while trying to install python-midi:

(env) C:\Users\Asus\Documents\LEI\Algo-Rhythm>pip install python-midi
Collecting python-midi
  Using cached python-midi-v0.2.4.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "C:\Users\Asus\AppData\Local\Temp\pip-build-zqxbr1j2\python-midi\setup.py", line 42
        print "No sequencer available for '%s' platform." % platform
                                                    ^
    SyntaxError: Missing parentheses in call to 'print'. Did you mean print(print "No sequencer available for '%s' platform." % platform)?

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\Asus\AppData\Local\Temp\pip-build-zqxbr1j2\python-midi\

I looked for the file where the error occurs but I can't find it even while viewing hidden files. If anybody knows what might be causing this or has experienced this issue as well I would be glad to hear. Thanks in advance.

Answer 1

The reason this error occurs is because this package is meant for Python 2. You can tell by the old style of print statement.

Python 2

print "hey"

Python 3

print("hey")

I'd recommend checking out python3-midi which has been forked out of the original python-midi package.

Answer 2

I have just updated the print statement in the setup.py file.

    def configure_platform():
        from sys import platform
        ns = __base__.copy()
        # currently, only the ALSA sequencer is supported
        if platform.startswith('linux'):
            setup_alsa(ns)
            pass
        else:
            print("No sequencer available for '%s' platform." % platform)
        return ns

I hope this might help you.
