Pyinstaller Onefile frozendict temp _MEI FILENOTFOUNDERROR

Question

我有一个使用conda-forge的yfinance包的脚本。它从特定股票的包中提取一些信息，然后将这些信息复制到剪贴板上，以便可以快速粘贴到基于文本的文档中。该脚本从我的Pycharm IDE运行，没有任何问题，但一旦我使用Pyinstaller将其打包到一个文件中，我就会遇到FileNotFoundError。下面是我得到的回溯:

我的Pyinstaller powershell命令是:Pyinstaller——onefile——name非常基础，在过去从未出现过任何问题。

这是我的。spec文件:

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

block_cipher = None

a = Analysis(
['C:\Users\USER\Coding\Projects\Portfolio_Watch\pw_news_aggregator.py'],
pathex=[],
binaries=[],
datas=[],
hiddenimports=[],
hookspath=[],
hooksconfig={},
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='PW News Aggregator',
debug=False,
bootloader_ignore_signals=False,
strip=False,
upx=True,
upx_exclude=[],
runtime_tmpdir=None,
console=True,
disable_windowed_traceback=False,
argv_emulation=False,
target_arch=None,
codesign_identity=None,
entitlements_file=None,
)

我试着做一个新的conda环境，认为它可能是损坏的。但同样的错误每次都会发生。我不知道为什么冻结会引起任何问题，它似乎是安装的。

同样，在回溯中，C路径包含不正确的用户名。我不确定这是Pyinstaller做的修订还是什么。它是:'C:UsersFirstNameLastInitial~1…，而应该是"C:UsersFirstNameLastName…">

任何想法都非常感谢!谢谢你！

Answer 1

这是因为frozendict模块在导入时读取__init__.py中的静态文件VERSION。但是PyInstaller只能分析脚本文件依赖链，不能识别静态文件依赖。

这相当困难，因为我们不容易在PyInstaller中从site-packages添加静态文件。(site-packages文件夹与project文件夹不同，这使得在spec文件中描述相关路径变得更加困难，并且还将该文件与其他frozendict项目文件绑定)

经过一些测试后，我添加了这段代码，可以看作是一个补丁，在主Python文件的最顶部，它将解决它。

import sys
if getattr(sys, 'frozen', False):
# because PyInstaller will NOT pack non-python text file into binary (in site-packages/frozendict/VERSION)
# after packing, it will cause a FileNotFoundError since frozendict.__init__ visits this file
# we generate it dynamically before importing frozendict to resolve this issue
with open(sys._MEIPASS + "/frozendict/VERSION", "w") as f:
f.write("2.3.1")

在二进制代码中，脚本启动后，frozendict导入之前，会动态生成VERSOIN文件，使frozendict.__init__能够找到VERSION文件。
