在exe中编译后如何使用pyinstaller修复错误

Question

我把一个Python脚本编译成exe文件，但是打开exe后，控制台打开报错，然后控制台立马关闭。也许这是因为我正在使用下载的库（web3、bs4、hdwallet、bip_utils）

看来您需要将项目中使用的文件复制到exe中。为此，您需要 add-data 当运行宁 pyinstaller。您可以使用 pyinstaller spec 文件来配置编译设置。

这里是一个spec文件的例子（您需要修改它以供您使用）：

a = Analysis(['C:\path\to\your\main\py file.py'],
             pathex=['C:\path\to\search\for\imports'],  
             binaries=[],
             datas=[('C:\Users\username\AppData\Local\Programs\Python\Python38\Lib\site-packages\package\xxxx\yyyyy\*', '.\package\xxxx\yyyyy'),
             ('C:\Users\username\AppData\Local\Programs\Python\Python38\Lib\site-packages\package2\zzz\*', '.\package2\zzz'),
             ],
             hiddenimports=["a_package"], #A list of module names (relative or absolute) that should be part of the bundled app
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=None,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=None)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='nameOfExe',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=False,
          icon='icon.ico') # specify icon

您可以从 Pyinstaller 文档中查看其他参数以及它们的作用。

此文件可以运行使用：

python -m PyInstaller -F main.spec --clean
