关于Pyinstaller打包eel和pygame需要注意的坑

这几天我们团队用python做了一个游戏，引擎用的pygame，UI界面用的eel（一个python库，用于利用HTML开发桌面应用程序，主要是因为QT机制太过复杂，而博主Deadpool不愿做费力不讨好的事，import一个eel，便可通过HTML、CSS、JS开发桌面应用程序，这简直不要太爽，另外，关于eel的使用也许我会在后续文章中写到）

1、打开cmd / Visual Studio等等可以装包的工具下载pyinstaller

如果是python环境，那么：pip install pyinstaller；如果是conda环境，那么：conda install pyinstaller

2、找到你的python_main程序

假设项目根目录为F:\xx\xx\xx，该目录的文件管理如下：

	- Web（包括HTML、CSS、JS）
	- 游戏资源文件夹 (包括图片巴拉巴拉的)
	- Class1.py (Class1中导入Class3)
	- Class2.py
	- Class3.py
	- Python_Main.py (Python_Main中导入Class1,Class2和eel)

3、查看eel库

eel库一般在site-pakages里

打开__main__.py文件

#eel的__main__.py文件
from __future__ import print_function
import sys
import pkg_resources as pkg
import PyInstaller.__main__ as pyi
import os
args = sys.argv[1:]
main_script = args.pop(0)
web_folder = args.pop(0)
print("Building executable with main script '%s' and web folder '%s'...\n" %
      (main_script, web_folder))
eel_js_file = pkg.resource_filename('eel', 'eel.js')
js_file_arg = '%s%seel' % (eel_js_file, os.pathsep)
web_folder_arg = '%s%s%s' % (web_folder, os.pathsep, web_folder)
needed_args = ['--hidden-import', 'bottle_websocket',
               '--add-data', js_file_arg, '--add-data', web_folder_arg]
full_args = [main_script] + needed_args + args
print('Running:\npyinstaller', ' '.join(full_args), '\n')
pyi.run(full_args)

注意到print(“Building executable with main script ‘%s’ and web folder ‘%s’…\n” %

(main_script, web_folder))和print(‘Running:\npyinstaller’, ’ '.join(full_args), ‘\n’)可以知道eel的打包原理还是利用pyinstaller

4、打开cmd开始将含有eel的python_main打包起来

python -m eel F:\xx\xx\xx\Python_Main.py F:\xx\xx\xx\Web

这里暂时不加-w -f -i参数。（因为无论如何必然会出错） 报错，提示找不到eel.js文件。呼呼，我就奇怪了，eel.js文件不就在那儿摆着吗。打开eel的__init__.py文件查看

_eel_js = open(_eel_js_file, encoding='utf-8').read()

ok，下面在运行一次cmd，执行之前的代码，不报错了。但是，这次又遇到了新的问题。

'utf-8' codec can't decode byte 0xce 

woc。这编码怎么又出了问题。百度一下，找到了解决方案。在cmd中先输入

chcp 65001

然后再执行

python -m eel F:\xx\xx\xx\Python_Main.py F:\xx\xx\xx\Web

这下总算是成功打包了。

5、找到我们的Python_Main.exe文件

打包后的文件一般在cmd的启动路径下能够找到。如，我的Python_Main.exe文件就应该在C:\Users\Deadpool里

发现在Deadpool文件里多出了三个文件，分别是Python_Main.spec, dist和build。打开dist后，发现有一个Python_Main文件夹，打开，便能找到Python_Main.exe，点击，弹出小黑框。接着，恭喜你，主界面显示404 Not Found。What？Woc。又是什么问题，难道我需要把Web文件夹移到这个Python_Main文件夹里？经验证答案是“是”。事实上，我们需要把所有文件都移到这个Python_Main里面，也就是前面的Web以及游戏资源文件夹。OK，问题解决。感动啊 (ಥ _ ಥ)~~~~当我满怀激情的点击了开始游戏，小黑框里又一个错误出现了：

pygame.error: Couldn't open xxx\xxx.png

百度一下，原来需要用pyinstaller打包时，pygame的load图片必须用绝对路径。ok，那就只有修改代码，重新打包。问题解决。接下来，就是如何处理掉小黑框了。现在，先让我们看看Python_Main.spec文件：

# -*- mode: python ; coding: utf-8 -*-
block_cipher = None
a = Analysis(['F:\\xx\\xx\\Python_Main.py'],
             pathex=['C:\\Users\\Deadpool'],
             binaries=[],
             datas=[('F:\\AnocondaApp\\lib\\site-packages\\eel\\eel.js', 'eel'), ('F:\\xx\\xx\\Web', 'F:\\xx\\xx\\Web')],
             hiddenimports=['bottle_websocket'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='Python_Main',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True, icon='')
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               upx_exclude=[],
               name='Python_Main')

简单分析后，把console = True改为console = False，咦，这里还有一个icon，应该不会是游戏图标吧，试着改改，于是我让icon = ‘F:\xx\xx\Web\favicon.ico’。改完后，保存。

如何运行spec文件呢？无所不能的网友给出了答案。

chcp 65001
pyinstaller Python_Main.spec

ok，完成。下面，就开始享受自己的exe游戏吧！！以上为个人经验，希望能给大家一个参考，也希望大家多多支持猪先飞。
