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
使用PyInstaller(开发版本为4.0.dev0 + 8196c57ab)时,产生了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
- GUI:PySide2 5.13.0
- 其他软件包:lxml,BeautifulSoup,Matplotlib(具有numpy之类的依赖项),Pandas,pypiwin32,reportlab,Theano
- Anaconda 3,Windows
- 使用PyInstaller --onedir编译
我尝试过的事情:
- 尝试按照以下建议将PyInstaller降级到2.1: https://github.com/pyinstaller/pyinstaller/issues/3916 ,但由于不支持Python 3而无法正常运行
- 最初是PyInstaller 3.5上的版本,根据PyInstaller github上某些问题的建议升级到开发版本.
- 尝试包括
--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

P.S.编译和exe可以与早先从Anaconda环境创建的virtualenv环境(不需要--exclude-module=.git
)一起正常运行,但是打包太肿,因为virtualenv环境仍然被认为是conda环境的一部分.所以我使用了一个新的conda环境,并且出现了这个错误
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round回的方式.有什么解决方法吗?
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
我通过以下方法解决了这个问题:
I solved this problem by:
-
在冻结之前将文件夹移出目录
此外,如果要运行冻结的应用程序需要该文件夹(例如,作为数据文件夹),我也可以:
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
的相应部分,然后手动复制文件夹,或者
Comment / remove the corresponding part for
--add-data
and manually copy the folder over, or
更改--add-data
的路径,例如如果将redacted_folder
移至桌面,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'
您仍然需要在原始目录中返回.git
和redacted_folder
才能使用Git并在不冻结的情况下运行代码
You'll still need .git
and redacted_folder
back in the original directory to use Git and run your code without freezing
例如,我在.git
和redacted_folder
上遇到麻烦.冻结的可执行文件需要redacted_folder
才能运行部分代码.
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:
-
将
.git
和redacted_folder
移动到单独的目录
然后,我注释掉为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:\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'
])
- 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.
- After freezing, I copied
redacted_folder
over to the appropriate location relative to the frozen executable indistpath
