anaconda - PyInstaller win32ctypes.pywin32.pywintypes.error : (2, 'LoadLibraryExW' , 'The system cannot find the file specified.')

Question

在使用 PyInstaller(开发版本 4.0.dev0+8196c57ab)时，产生了 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 编译 --onedir

我试过的:

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 dev 版本

尝试包括 --exclude-module=.git

import PyInstaller.__main__

if __name__ == '__main__':
    PyInstaller.__main__.run([
        '--name=%s' % 'Dummy App',
        '--onedir',
        '--nowindowed',
        r'--workpath=C:\Users\User1\Desktop\build7',
        r'--distpath=C:\Users\User1\Desktop\dist7',
        '--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'
    ])

附言编译和 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 conda 环境的一部分，所以包过于臃肿。于是我用了新的conda环境，出现了这个错误

我已经通过在这个新的 conda 环境中创建另一个 virtualenv 环境来让它工作，但这是一种非常迂回的方式。有什么解决方法吗？

Answer 1

对我来说，PyInstaller 似乎在搜索 .git文件夹和 redacted_folder不必要的

我通过以下方式解决了这个问题:

在卡住前将文件夹移出目录

此外，如果运行卡住的应用程序需要该文件夹(例如，作为数据文件夹)，我也会:

评论/删除 --add-data 的对应部分并手动复制文件夹，或

更改 --add-data 的路径例如如果您搬家 redacted_folder到您的桌面，您可以更改为 '--add-data=C:/Users/User1/Desktop/redacted_folder'

您仍然需要 .git和 redacted_folder返回原始目录以使用 Git 并在不卡住的情况下运行您的代码

例如，我遇到了 .git 的问题。和 redacted_folder .需要卡住的可执行文件redacted_folder运行部分代码。

我所做的是:

移动.git和 redacted_folder到一个单独的目录

然后，我注释掉了为 redacted_folder 添加数据的行:

import PyInstaller.__main__

if __name__ == '__main__':
    PyInstaller.__main__.run([
        '--name=%s' % 'Dummy App',
        '--onedir',
        '--nowindowed',
        r'--workpath=C:\Users\User1\Desktop\build7',
        r'--distpath=C:\Users\User1\Desktop\dist7',
        '--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'
    ])

卡住后，我复制了redacted_folder移动到相对于 distpath 中卡住的可执行文件的适当位置
