Python打包工具之pyinstaller

前言: 近期使用PySimpleGUI开发了一款开发者工具X-助手工具,意打造成平常开发助手,无论是图片还是网址的处理等等都需要这一个工具即可,无需在网上找各个网站去找解决方案, 对于GUI的打包工具,在Python领域pyinstaller较为流行

工具样例:

安装:

pip install -U pyinstaller 

使用:

常见问题:

1.在识别二维码过程中用到了pyzbar这个库,开发环境可以正常使用, 但是在打包完之后,打开确实报错的状态

Traceback (most recent call last):
  File "pyzbar\zbar_library.py", line 58, in load
  File "pyzbar\zbar_library.py", line 50, in load_objects
  File "pyzbar\zbar_library.py", line 51, in <listcomp>
  File "ctypes\__init__.py", line 447, in LoadLibrary
  File "PyInstaller\loader\pyimod04_ctypes.py", line 56, in __init__
pyimod04_ctypes.PyInstallerImportError: Failed to load dynlib/dll 'libiconv.dll'. Most probably this dynlib/dll was not found when the application was frozen.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "PyInstaller\loader\pyimod04_ctypes.py", line 54, in __init__
  File "ctypes\__init__.py", line 369, in __init__
FileNotFoundError: Could not find module 'D:\代码\weebot\main\pyzbar\libiconv.dll'. Try using the full path with constructor syntax.

The above exception was the direct cause of the following exception:

　　解决:

第一种方法：在自己的虚拟环境中找到该模块的dll(libiconv.dll+libzbar-64.dll),手动复制粘贴到打包后目录(dist)即可：但是这种拷贝到另外一个地方使用的时候,这些dll文件也要一并拷贝过去,不够方便,或者将其加入全局变量使用

 第二种方法：修改spec文件的时候设置好导入位置，打包时会自动识别

# -*- mode: python ; coding: utf-8 -*-

dll_path = 'E:\\python-project\\x-helper\\env\\Lib\\site-packages\\pyzbar\\'

a = Analysis(
    ['main.py'],
    pathex=[],
    binaries=[(dll_path+'libiconv.dll', '.'), (dll_path+'libzbar-64.dll', '.'),],
    datas=[],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    noarchive=False,
    optimize=0,
)
pyz = PYZ(a.pure)

exe = EXE(
    pyz,
    a.scripts,
    a.binaries,
    a.datas,
    [],
    name='X-助手工具',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    upx_exclude=[],
    runtime_tmpdir=None,
    console=False,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
    icon=['icon.ico'],
)

2. FileNotFoundError: Could not find module '你的路径\Python\Python38\site-packages\pyzbar\libzbar-64.dll' (or one of its dependencies). Try using the full path with constructor syntax

解决: 需要安装visual C++的库
