Pyinstaller：导入错误：DLL 加载失败：找不到指定的模块

Question

我正在尝试从我的代码中创建一个使用 PyQt5 的可执行文件。我正在使用 Python 3.5.3 -64 位，在 Windows 10 中开发，并使用 pip 安装 pyinstaller 3.2.1。

我这样运行 pyinstaller：

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

我收到导入错误：

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.

我读到这意味着 pip 没有安装 pywin32，我需要安装这个 Microsoft Visual Package：https://www.microsoft.com/en-us/download/details.aspx?id=5555。我下载并安装了它，但我得到了同样的错误。

编辑：

从 sourceforge.net/projects/pywin32/files/pywin32/Build%20221 安装 pywin32 后，导入错误消失了，但我在运行时收到警告（输出长达数百行，这是一个 sn -p):

pyinstaller main.py

....

然后我运行：

pyinstaller main.spec

并得到类似的警告。生成的 exe 文件立即关闭。

你需要安装pyinstaller和pywin32，这和你的python位版本是一样的。

从这里获取：https://sourceforge.net/projects/pywin32/files/pywin32/Build%20214/

如果您的 python 是 64 位，则选择 amd64 的，否则选择非 amd64 的

如果您遇到任何注册表问题（或）Python 安装目录未找到问题，我可以提供帮助
