Pyinstaller“FileNotFoundError:[Errno 2]运行应用程序时没有此类文件或目录：”

Question

我最近使用pyinstaller --onefile命令打包了一个python应用程序。它成功地生成了一个启动良好的可执行文件。我几乎可以毫无问题地使用脚本中的所有函数，除了一个。当我调用另一个python文件（在我的应用程序文件夹中）的函数时，会出现以下错误：

Traceback (most recent call last):
  File "socketserver.py", line 647, in process_request_thread
  File "socketserver.py", line 357, in finish_request
  File "socketserver.py", line 717, in __init__

问题似乎是pyinstaller无法正确找到文件（icon.png和ga.hunk.html）。这些文件位于与我的main.py文件位于同一文件夹中的文件夹中。我想知道如何让pyinstaller成功地找到这些文件？我曾尝试将其添加到.spec文件中的datas类中，但仍然出现错误。这就是那行的样子：datas=[('/Users/A/Desktop/ss/CaptchaHarvester/harvester/server/icon.png','/Users/A/Desktop/ss/CaptchaHarvester/harvester/server')], 请让我知道，如果我做错了什么，或者如果你有任何想法如何解决它

如果有帮助的话，我正在使用macosx catalina和python 3.7

谢谢

您可以在命令提示符中使用参数，以确保pyinstaller找到正确的文件 add-data "path_to_file:path_in_executable in directory"一个例子是

pyinstaller  add-data "icon.png;."  onefile socketserver.py

此处icon.png位于socketserver.py的同一目录中，并被复制到可执行文件的根目录中（.表示根目录）
