我尝试编译一个exe文件，但一直遇到FileNotFoundError错误，报错信息如下：

我的目录结构里有两个项目文件夹：

C:\Users\source\repos\PowerProjects\Solutions\HQ Daily Hedge Report\DHR_SwapTradingExposure
C:\Users\source\repos\PowerProjects\Solutions\HQ Daily Hedge Report\DHR_ConsolidateMarks

用pyinstaller --onedir --add-data "config1.json;." DHR_ConsolidateMarks.py编译第二个项目时完全正常，但用pyinstaller --onedir --add-data "config.json;." DHR_SwapTradingExposure.py编译第一个项目就会出现上面的文件找不到错误，我完全搞不懂为什么会这样，有没有人能帮我解决这个问题？

可能的解决思路

看起来这个问题是PyInstaller在收集依赖文件时，尝试复制一个不存在的_implementation.pyi文件导致的，大概率和jedi库的依赖收集有关。这里有几个你可以尝试的方案：

清理PyInstaller缓存后重新编译
有时候缓存的旧文件会导致奇怪的问题，先删除项目里的build、dist文件夹和生成的.spec文件，然后重新运行编译命令：
```
rmdir /s /q build dist
del DHR_SwapTradingExposure.spec
pyinstaller --onedir --add-data "config.json;." DHR_SwapTradingExposure.py
```
排除jedi相关的不必要依赖
如果你的项目并没有用到jedi库（它通常是代码补全工具的依赖），可以在编译时主动排除它：
```
pyinstaller --onedir --add-data "config.json;." --exclude-module jedi DHR_SwapTradingExposure.py
```
如果确实需要用到jedi，那可以尝试升级jedi和PyInstaller到最新版本，可能是旧版本的兼容性问题：
```
pip install --upgrade jedi pyinstaller
```
手动创建缺失的目录或文件
报错里提到的路径是dist\DHR_SwapTradingExposure\_internal\jedi\third_party\typeshed\third_party\2and3\requests\packages\urllib3\packages\ssl_match_hostname，你可以手动创建这个目录结构，甚至可以从jedi的安装目录里找到对应的_implementation.pyi文件复制过去，然后再重新编译。
你可以在Python的site-packages目录里找jedi的位置，比如C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python39_64\lib\site-packages\jedi，然后找到对应的文件路径复制过去。
修改.spec文件跳过该文件
生成.spec文件后，打开它找到COLLECT部分，尝试添加排除规则，或者修改文件收集的逻辑，跳过这个不存在的文件。比如在a = Analysis(...)部分的excludes列表里加上对应的路径，或者在COLLECT里过滤掉这个文件。
