PyInstaller win32ctypes.pywin32.pywintypes.error: (2, 'LoadLibraryExW', '系统找不到指定的文件.') [英] PyInstaller win32ctypes.pywin32.pywintypes.error: (2, 'LoadLibraryExW', 'The system cannot find the file specified.')

问题描述

在使用 PyInstaller (dev version 4.0.dev0+8196c57ab) 时，产生 OSError: [WinError 2] 'The system cannot find the file specified.'

While using PyInstaller (dev version 4.0.dev0+8196c57ab), produced an OSError: [WinError 2] 'The system cannot find the file specified.'

• Python 版本:3.7
• 图形用户界面:PySide2 5.13.0
• 其他包:lxml、BeautifulSoup、Matplotlib(带有 numpy 等依赖项)、Pandas、pypiwin32、reportlab、Theano
• Anaconda 3，Windows
• 使用 PyInstaller --onedir 编译

我尝试过的:

• 尝试按照此处的建议将 PyInstaller 降级到 2.1:https://github.com/pyinstaller/pyinstaller/issues/3916 但由于不支持 Python 3 而无法使用
• 最初在 PyInstaller 3.5 上，按照 PyInstaller github 上的一些问题的建议升级到开发版本
• 尝试包含 --exclude-module=.git

• Tried downgrading PyInstaller to 2.1 as suggested here: https://github.com/pyinstaller/pyinstaller/issues/3916 but doesn't work as Python 3 is not supported
• Was originally on PyInstaller 3.5, upgraded to dev version as suggested under some of the issues on PyInstaller github
• Tried including --exclude-module=.git

import PyInstaller.__main__

if __name__ == '__main__':
    PyInstaller.__main__.run([
        '--name=%s' % 'Dummy App',
        '--onedir',
        '--nowindowed',
        r'--workpath=C:UsersUser1Desktopuild7',
        r'--distpath=C:UsersUser1Desktopdist7',
        '--hidden-import=theano.tensor.shared_randomstreams',
        '--hidden-import=pandas._libs.tslibs.timedeltas',
        '--clean',
        '--add-data={0};.'.format('redacted.xml'),
        '--add-data={0};{0}'.format('redacted_folder'),
        '--add-data={0};.'.format('redacted.pdf'),
        '--exclude-module={0}'.format('.git'),
        '--log-level=WARN',
        'MainWindow.py'
    ])

附:编译和 exe 与之前从 Anaconda 环境创建的 virtualenv 环境完美运行(不需要 --exclude-module=.git)，但是由于 virtualenv 环境仍然被认为是，所以包过于臃肿conda 环境的一部分.于是我用了新的conda环境，就出现了这个错误

P.S. Compilation and the exe functioned perfectly with virtualenv environment created from Anaconda environment earlier (without need for --exclude-module=.git), but was too bloated with packages because the virtualenv environment is still considered to be part of the conda environment. So I used a new conda environment, and this error appeared

我已经通过在这个新的 conda 环境中创建另一个 virtualenv 环境来使其工作，但这是一种非常迂回的方式.有什么解决办法吗?

I've gotten it to work by creating another virtualenv environment in this new conda environment, but that is a very roundabout way. Is there any workaround?

推荐答案

对我来说，PyInstaller 似乎不必要地搜索 .git 文件夹和 redacted_folder

For me, PyInstaller seems to search through .git folder and redacted_folder unnecessarily

我通过以下方式解决了这个问题:

I solved this problem by:

1. 将文件夹移出目录在冻结之前

此外，如果运行冻结的应用程序需要该文件夹(例如，作为数据文件夹)，我也会:

Additionally, if the folder is required for the frozen app to run (e.g. as a data folder), I would also either:

• 注释/删除 --add-data 的对应部分并手动复制文件夹，或

• Comment / remove the corresponding part for --add-data and manually copy the folder over, or

更改 --add-data 的路径，例如如果您将 redacted_folder 移动到桌面，则可以更改为 '--add-data=C:/Users/User1/Desktop/redacted_folder'

Change the path for --add-data e.g. if you moved redacted_folder to your Desktop, you can change to '--add-data=C:/Users/User1/Desktop/redacted_folder'

您仍然需要返回原始目录中的 .git 和 redacted_folder 才能使用 Git 并在不冻结的情况下运行您的代码

You'll still need .git and redacted_folder back in the original directory to use Git and run your code without freezing

例如，我遇到了 .git 和 redacted_folder 的问题.冻结的可执行文件需要 redacted_folder 来运行部分代码.

For example, I had trouble with .git and redacted_folder. The frozen executable needed redacted_folder to run parts of the code.

我所做的是:

1. 将 .git 和 redacted_folder 移至单独的目录

1. Move .git and redacted_folder to a separate directory

然后，我注释掉了为 redacted_folder 添加数据的行:

Then, I commented out the line to add data for redacted_folder:

import PyInstaller.__main__

if __name__ == '__main__':
    PyInstaller.__main__.run([
        '--name=%s' % 'Dummy App',
        '--onedir',
        '--nowindowed',
        r'--workpath=C:UsersUser1Desktopuild7',
        r'--distpath=C:UsersUser1Desktopdist7',
        '--hidden-import=theano.tensor.shared_randomstreams',
        '--hidden-import=pandas._libs.tslibs.timedeltas',
        '--clean',
        '--add-data={0};.'.format('redacted.xml'),
        # Remove `redacted_folder` and comment out the following line
        # '--add-data={0};{0}'.format('redacted_folder'),
        '--add-data={0};.'.format('redacted.pdf'),
        '--exclude-module={0}'.format('.git'),
        '--log-level=WARN',
        'MainWindow.py'
    ])

1. 冻结后，我将 redacted_folder 复制到相对于 distpath
中冻结的可执行文件的适当位置

1. After freezing, I copied redacted_folder over to the appropriate location relative to the frozen executable in distpath
