PyInstaller win32ctypes.pywin32.pywintypes.error: (2, 'LoadLibraryExW', '系统找不到指定的文件。')

Question

在使用 PyInstaller（开发版本 4.0.dev0+8196c57ab）时，产生了一个 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（依赖于 numpy）、Pandas、pypiwin32、reportlab、Theano
• 蟒蛇 3, 视窗
• 使用 PyInstaller --onedir 编译

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但不起作用，因为不支持 Python 3
• 最初是在 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'
    ])

PS 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），但由于包过于臃肿，因为 virtualenv 环境仍然被认为是 conda 环境的一部分。于是我用了新的conda环境，出现了这个错误

我通过在这个新的 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 似乎不必要地搜索.git文件夹redacted_folder

我通过以下方式解决了这个问题：

1. 在冻结之前将文件夹移出目录

2. 此外，如果冻结的应用程序运行需要该文件夹（例如作为数据文件夹），我还可以：

   • 注释/删除相应部分--add-data并手动复制文件夹，或

   • 更改路径，--add-data例如，如果您移动redacted_folder到桌面，则可以更改为'--add-data=C:/Users/User1/Desktop/redacted_folder'

您仍然需要.git并redacted_folder回到原来的目录使用Git和不冻结运行代码

例如，我在使用.gitand 时遇到了麻烦redacted_folder。redacted_folder运行部分代码所需的冻结可执行文件。

我所做的是：

1. 移动.git和redacted_folder到一个单独的目录

2. 然后，我注释掉了添加数据的行redacted_folder：

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'
    ])

3. 冻结后，我复制redacted_folder到与冻结的可执行文件相关的适当位置distpath
