如何通过Python创建适用于Python脚本的Mac应用程序捆绑包 [英] How to create Mac application bundle for Python script via Python

问题描述

我想创建一个简单的Mac应用程序捆绑包，该捆绑包调用一个简单的Python脚本.我想用Python做到这一点.

I want to create a simple Mac application bundle which calls a simple Python script. I want to do that in Python.

有简单的方法吗?

我尝试使用py2app，但是以某种方式失败，例如:

I tried to use py2app but that fails somehow, e.g.:

from setuptools import setup
setup(app=["foo.py"], setup_requires=["py2app"])

给予:

---------------------------------------------------------------------------
SystemExit                                Traceback (most recent call last)
/Users/az/<ipython console> in <module>()

/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/distutils/core.pyc in setup(**attrs)
    138         ok = dist.parse_command_line()
    139     except DistutilsArgError, msg:
--> 140         raise SystemExit, gen_usage(dist.script_name) + "\nerror: %s" % msg
    141 
    142     if DEBUG:

SystemExit: usage: ipython [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: ipython --help [cmd1 cmd2 ...]
   or: ipython --help-commands
   or: ipython cmd --help

error: no commands supplied
Type %exit or %quit to exit IPython (%Exit or %Quit do so unconditionally).

我也尝试过:

import py2app.build_app
py2app.build_app.py2app("foo.py")

这也不起作用(TypeError: dist must be a Distribution instance)(我不太确定如何使用py2app.build_app.py2app，也没有真正找到很多有关此的示例/文档).

which also doesn't work (TypeError: dist must be a Distribution instance) (I'm not really sure how to use py2app.build_app.py2app and also haven't really found much examples / documentation about it).

对于我的用例而言，也许setuptools/py2app左右都是过大的.我只想创建一个简单的空应用程序包，将Python脚本复制到其中，并以调用Python脚本的方式配置它的Info.plist.

Maybe setuptools/py2app or so are anyway overkill for my use case. I just want to create a simple empty app bundle, copy a Python script into it and configure its Info.plist in such a way that it calls the Python script.

推荐答案

这正是我想要的并且可以正常工作:

This is exactly what I wanted and works just fine:

#!/usr/bin/python

import sys
assert len(sys.argv) > 1

apppath = sys.argv[1]

import os, os.path
assert os.path.splitext(apppath)[1] == ".app"

os.makedirs(apppath + "/Contents/MacOS")

version = "1.0.0"
bundleName = "Test"
bundleIdentifier = "org.test.test"

f = open(apppath + "/Contents/Info.plist", "w")
f.write("""<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</dict>
</plist>
""" % (bundleName + " " + version, bundleIdentifier, bundleName, bundleName + " " + version, version))
f.close()

f = open(apppath + "/Contents/PkgInfo", "w")
f.write("APPL????")
f.close()

f = open(apppath + "/Contents/MacOS/main.py", "w")
f.write("""#!/usr/bin/python
print "Hi there"
""")
f.close()

import stat
oldmode = os.stat(apppath + "/Contents/MacOS/main.py").st_mode
os.chmod(apppath + "/Contents/MacOS/main.py", oldmode | stat.S_IXUSR | stat.S_IXGRP | stat.S_IXOTH)
