Pyinstaller：导入错误：DLL加载失败：无法找到指定的模块

Question

我试图从我的代码使用PyQt5创建一个可执行文件。我使用Python 3.5.3 -64位，在Windows 10中开发，并使用pip来安装pyinstaller 3.2.1。

我跑这样pyinstaller：

pyinstaller.exe --onefile --windowed main.py 

我得到一个导入错误：

File "C:\Python35\Scripts\pyinstaller-script.py", line 11, in <module> load_entry_point('PyInstaller==3.2.1', 'console_scripts', 'pyinstaller')() 
File "C:\Python35\lib\site-packages\pkg_resources\__init__.py", line 565, in load_entry_point 
return get_distribution(dist).load_entry_point(group, name) 
File "C:\Python35\lib\site-packages\pkg_resources\__init__.py", line 2631, in load_entry_point 
return ep.load() 
File "C:\Python35\lib\site-packages\pkg_resources\__init__.py", line 2291, in load 
return self.resolve() 
File "C:\Python35\lib\site-packages\pkg_resources\__init__.py", line 2297, in resolve 
module = __import__(self.module_name, fromlist=['__name__'], level=0) 
File "C:\Python35\lib\site-packages\PyInstaller\__main__.py", line 21, in <module> 
import PyInstaller.building.build_main 
File "C:\Python35\lib\site-packages\PyInstaller\building\build_main.py", line 32, in <module> 
from ..depend import bindepend 
File "C:\Python35\lib\site-packages\PyInstaller\depend\bindepend.py", line 38, in <module> 
from ..utils.win32.winmanifest import RT_MANIFEST 
File "C:\Python35\lib\site-packages\PyInstaller\utils\win32\winmanifest.py", line 97, in <module> 
from PyInstaller.utils.win32 import winresource 
File "C:\Python35\lib\site-packages\PyInstaller\utils\win32\winresource.py", line 20, in <module> 
import pywintypes 
File "C:\Python35\lib\site-packages\win32\lib\pywintypes.py", line 124, in <module> 
__import_pywin32_system_module__("pywintypes", globals()) 
File "C:\Python35\lib\site-packages\win32\lib\pywintypes.py", line 64, in __import_pywin32_system_module__ 
import _win32sysloader 
ImportError: DLL load failed: The specified module could not be found. 

我读过这个意义pywin32不是由PIP和安装我需要安装此Microsoft Visual Package：https://www.microsoft.com/en-us/download/details.aspx?id=5555。我下载并安装它，但我得到相同的错误。

编辑：

从sourceforge.net/projects/pywin32/files/pywin32/Build%20221安装pywin32后，导入错误消失，但是当它运行我得到警告（输出数百行的长，这里是一个片段）：

pyinstaller main.py 

....

9366 WARNING: lib not found: api-ms-win-crt-string-l1-1-0.dll dependency of C:\Python35\lib\site-packages\PyQt5\Qt\plugins\imageformats\qgif.dll 

然后我运行：

pyinstaller main.spec 

，并得到了类似的警告。生成的exe文件立即关闭。

你需要安装pyinstaller和pywin32，它与你的python版本是相同的位版本。

从这里得到它：https://sourceforge.net/projects/pywin32/files/pywin32/Build%20214/

选择AMD64的，如果你的Python是64位的其他非AMD64那些

如果您遇到任何注册表问题（或）Python安装目录中没有发现的问题，我可以帮助
