Importlib ModuleNotFound Error

[Leonmmcoset]

I write the code:

#Outside App Running System File#
import os
import subprocess
import importlib

    def find_and_run_script(script_name):
        """查找并运行脚本"""
        # 获取 _internal/app/py 文件夹的路径
        script_dir = "_internal/app"

        # 遍历该文件夹中的所有文件
        for file_name in os.listdir(script_dir):
            # 如果文件名与输入的脚本名匹配
            if file_name == script_name + ".py":
                # 构建脚本文件的绝对路径
                script_path = os.path.join(script_dir, file_name)

                # 动态导入脚本
                try:
                    module = importlib.import_module(f"_internal.app.{script_name}")
                    # 调用脚本中的 start() 函数
                    module.start()
                except ModuleNotFoundError:
                    print(f"Script '{script_name}' not found.")
                except AttributeError:
                    print(f"Script '{script_name}' does not have a 'start()' function.")

                return True

        # 如果没有找到匹配的脚本
        print(f"No script named '{script_name}.py' found.")
        return False


    def start():
        """开始函数"""
        # 提示用户输入要运行的脚本名
        script_name = input("Enter the app name: ")

        # 查找并运行脚本
        find_and_run_script(script_name)

    start()

It work in source code,but isn't work in pyinstaller,it has ''Script '{script_name}' not found.''

That's because PyInstaller's import analysis cannot pick up imports of modules with dynamically computed names (or pretty much anything that is not imported using regular import statement).

And even if it did, it would collect the modules into PYZ archive, so you would not be able to discover them via os.listdir.

---

You will either need to ensure that those script files are collected as data files (but then you will also need to add all their dependencies to hidden imports), or collect them as submodules of app and then force collection of .py files as well (either as data files, or by setting module collection mode to either pyz+py or py).

[Leonmmcoset]

If Pyinstaller compile .py to .exe,I will going to add .py files to _internal/app/
Like I will add test.py to _internal/app,I want the appcation run the test.py.
How can I do it?

[rokm]

Using --add-data would be one option.

But note that such external scripts do not undergo dependency analysis, so you will end up with missing modules unless those modules were collected at build time.

[Leonmmcoset]

This is my command,does it right?

import os
os.system(f'pyinstaller --add-data "bin/_internal/audio:audio"\
          --add-data "bin/_internal/font:font"\
          --add-data "bin/_internal/image:image"\
          --add-data "bin/_internal/app:app"\

          -D -y \
          C:\\Users\leonm\PycharmProjects\leonsystem\\bin\cmd.py')

You are misusing --path. And you have inconsistently escaped \ separators in paths.

But I guess if you see those .py files collected where they should be, then you might call it "right".

[Leonmmcoset]

But this isn't working,how can I do it?

[rokm]

Are the .py files collected in application's _internal/app directory or not?

[rokm]

Actually, this is likely the culprit:

module = importlib.import_module(f"_internal.app.{script_name}")

In the frozen application, the module should be called app.{script_name}, since _internal directory is in the search path (as opposed to its parent).

[Leonmmcoset]

I know!This problem!

[ChillarAnand]

I am facing a similar issue with my project.

 foo = import_module(f"avilpage.read_csv.parser.{class_name}")

This works with python script but not with pyinstaller.
