导出时 Pyinstaller 和 Pandas 错误

Question

我有一个使用 tkinter 和 Pandas 的工作项目，但每当我尝试使用 Pyinstaller 导出它时，当我将 pandas 导入我的项目时，它会显示错误。

这是我第一次导出到 exe。我已经重新安装了 pyinstaller pyqt5、pandas，但仍然没有。 我正在使用

• Windows 10
• python 3.6
• 我使用 Pip 安装库

库：pandas、pyinstaller。

Answer 1

collect_system_data_files(pyqt5_library_info.location['PrefixPath']

这表明在收集系统数据文件时出现错误。尝试安装 PyQt5，然后运行 ​​PyInstaller。

Answer 2

我遇到了同样的问题。经过几个小时的折腾，我相信删除我计算机上的旧版 python 是修复它的原因，尽管我不能绝对肯定，因为我做了很多事情。如果你有其他版本的 python，我建议尝试卸载它们，然后通过 pip 卸载并重新安装程序的依赖项。然后确保您能够从 cmd：C:\<path to the location of myProgram>\>python myProgram.py 运行您的 python 脚本myProgram.py。解决在尝试使用 pyinstaller 之前可能发生的任何错误，它为我解决了这个特定错误。
