Django 1.11.7-Django压缩器-参数5：<class 'TypeError'>：预期的LP_OVERLAPPED实例而不是指向重叠的指针
我正试图在我的Windows 10框上安装和运行一个现有的Django 1.11.7 (Python3.5)项目。设置好环境之后，我现在在运行应用程序之后看到主页，但是我访问的任何内部页面都会出现以下错误：
argument 5: <class 'TypeError'>: expected LP_OVERLAPPED instance instead of pointer to OVERLAPPED
我从compress.py (Django压缩程序)调用一些压缩的CSS文件，到django.core内部的一些win32文件锁定代码，特别是这一行：https://github.com/django/django/blob/master/django/core/files/locks.py#L86 (下面的snip中的UnlockFileEx)。
class OVERLAPPED(Structure):
_anonymous_ = ['_offset_union']
_fields_ = [
('Internal', ULONG_PTR),
('InternalHigh', ULONG_PTR),
('_offset_union', _OFFSET_UNION),
('hEvent', HANDLE)]
LPOVERLAPPED = POINTER(OVERLAPPED)
....
def lock(f, flags):
hfile = msvcrt.get_osfhandle(_fd(f))
overlapped = OVERLAPPED()
ret = LockFileEx(hfile, flags, 0, 0, 0xFFFF0000, byref(overlapped))
return bool(ret)
def unlock(f):
hfile = msvcrt.get_osfhandle(_fd(f))
overlapped = OVERLAPPED()
ret = UnlockFileEx(hfile, 0, 0, 0xFFFF0000, byref(overlapped))
return bool(ret)奇怪的是，在主页上调用LockFileEx和UnlockFileEx方法都没有错误。在成功和不成功的电话中检查当地人都没有发现任何结果。
堆栈跟踪，以防有帮助(更高的堆栈编辑)：
File "C:\x\env\lib\site-packages\compressor\templatetags\compress.py", line 127, in render
return self.render_compressed(context, self.kind, self.mode, forced=forced)
File "C:\x\env\lib\site-packages\compressor\templatetags\compress.py", line 103, in render_compressed
rendered_output = compressor.output(mode, forced=forced)
File "C:\x\env\lib\site-packages\compressor\css.py", line 49, in output
ret.append(subnode.output(*args, **kwargs))
File "C:\x\env\lib\site-packages\compressor\css.py", line 51, in output
return super(CssCompressor, self).output(*args, **kwargs)
File "C:\x\env\lib\site-packages\compressor\base.py", line 292, in output
output = '\n'.join(self.filter_input(forced))
File "C:\x\env\lib\site-packages\compressor\base.py", line 232, in filter_input
for hunk in self.hunks(forced):
File "C:\x\env\lib\site-packages\compressor\base.py", line 215, in hunks
basename=basename)
File "C:\x\env\lib\site-packages\compressor\base.py", line 307, in handle_output
return output_func(mode, content, forced, basename)
File "C:\x\env\lib\site-packages\compressor\base.py", line 319, in output_file
self.storage.save(new_filepath, ContentFile(content.encode(self.charset)))
File "C:\x\env\lib\site-packages\django\core\files\storage.py", line 54, in save
return self._save(name, content)
File "C:\x\env\lib\site-packages\django\core\files\storage.py", line 357, in _save
locks.unlock(fd)
File "C:\x\env\lib\site-packages\django\core\files\locks.py", line 86, in unlock
ret = UnlockFileEx(hfile, 0, 0, 0xFFFF0000, byref(overlapped))使用锁定/解锁的文件似乎是静态CSS文件。JS和LESS都是抛出上述异常的。该项目似乎同时为CSS和JS过滤器使用yuglify，如果这有帮助的话。

在我的例子中，这是由于与youtube-dl包的冲突，该包具有与django-压缩程序包同名的类、变量和方法。我能够通过在这两种情况下“侵入”各种令牌的名称来确认这一点，从而导致了一个错误的argument 5: <class 'TypeError'>: expected LP_OVERLAPPED2 instance instead of pointer to OVERLAPPED3。
目前，我已经从我的环境中删除了youtube-dl包，作为在本地开发环境中运行该程序的临时解决方案。
