pyinstall打包资源文件

Posted 2021-03-22 chusiyong

相关代码

main.py

import sys
import os

#生成资源文件目录访问路径
#说明： pyinstaller工具打包的可执行文件，运行时sys。frozen会被设置成True
#      因此可以通过sys.frozen的值区分是开发环境还是打包后的生成环境
#
#      打包后的生产环境，资源文件都放在sys._MEIPASS目录下
#      修改main.spec中的datas，
#      如datas=[(‘res‘, ‘res‘)]，意思是当前目录下的res目录加入目标exe中，在运行时放在零时文件的根目录下，名称为res

def resource_path(relative_path):
    if getattr(sys, ‘frozen‘, False):
        base_path = sys._MEIPASS
    else:
        base_path = os.path.abspath(".")
    return os.path.join(base_path, relative_path)

filename = resource_path(os.path.join("res","a.txt"))
print(filename)

with open(filename) as f:
    lines = f.readlines()
    print(lines)
    f.close()

 

 res/a.txt

1 2 3
4 5 6

 

 打包流程

1.  生成main.spec文件：pyi-makespec -F test.py
2. 修改mian.spec文件，如下
3. pyinstaller -F main.spec

# -*- mode: python -*-

block_cipher = None


a = Analysis([‘main.py‘],
             pathex=[‘C:\Users\xxx\PycharmProjects\Test‘],
             binaries=[],
             datas=[(‘res‘, ‘res‘)], //重点
             hiddenimports=[],
             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,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name=‘main‘,
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          runtime_tmpdir=None,
          console=True )

解决办法：

　　这是个已知的故障，官方已经修改，但是没有正式的版本支持。下载https://github.com/Loran425/pyinstaller/tree/14b6e65642e4b07a4358bab278019a48dedf7460中PyInstaller里的bindepend.py文件，然后替换掉本地安装包里的bindepend.py文件即可。
