PyInstaller exe文件可以分发吗？

Question

I converted a.py file to.exe using pyinstaller and made a copy of the whole directory on another machine (same version of OS). What happen is that when I run it, it will prompt some errors.

developer1 is the machine that developed the script, user1 is the machine where I distribute the program to.

C:\Users\user1\Downloads\MyApp\dist\app>app.exe

During handling of the above exception, another exception occurred:

[10460] Failed to execute script app

I checked the .spec file and found out that the pathex path is actually the developer machine path, I believe this is actually causing all these errors? Is there a fix for this or the.exe is meant to be run on the developer machine only?

Just a side info:

1. I did not use virtual environment when building the application, not sure if this is causing these errors.
2. The user1 machine do not have python installed

In this .spec file

a = Analysis(['app.py'],
             pathex=['C:\\Users\\developer1\\App1'],
             binaries=[],
             datas=[],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)

Do I need bother about the pathex being the path of developer machine?

Update:

1. Yes pyinstaller exe file can be distributed
2. Most ModuleNotFoundError can be solved by using --hiddenimport as mentioned in the answer accepted.
3. There's no need to bother about the pathex being different from user path

Answer 1

type pyinstaller app.py --hiddenimport=pandas._libs.tslibs.offsets when building the app

since you posted the spec file... you can put this in and just use pyinstaller app.spec

a = Analysis(['app.py'],
         pathex=['C:\\Users\\developer1\\App1'],
         binaries=[],
         datas=[],
         hiddenimports=['pandas._libs.tslibs.offsets'],
         hookspath=[],
         runtime_hooks=[],
         excludes=[],
         win_no_prefer_redirects=False,
         win_private_assemblies=False,
         cipher=block_cipher,
         noarchive=False)
