如何在cython中编译pyqt5和python代码

可以用python3和pyqt5以及cython编译我的项目吗

我创建了一个compyle.py文件，其中包含以下内容：

from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_modules = [
    Extension("Main",  ["Main.py"]),
    Extension("MainWindow",  ["MainWindow.py"]),
    Extension("CopyDialog",  ["CopyDialog.py"]),
    Extension("CopyDebugThread",  ["CopyDebugThread.py"])

]
setup(
    name = 'My Program Name',
    cmdclass = {'build_ext': build_ext},
    ext_modules = ext_modules
)

我根据以下说明运行此文件：

但我有一个错误：

$ python3 compile.py build_ext --inplace
running build_ext

/home/groot/.local/lib/python3.6/site-packages/Cython/Compiler/Main.py:367: FutureWarning: Cython directive 'language_level' not set, using 2 for now (Py2). This will change in a later release! File: /home/groot/PythonProject/ConfigServer/Main.py

我认为cython可以编译

PyQt5

模块？我该怎么做呢？

虽然python允许使用

app.exec（）

，但cython更严格，解决方案是使用

app.exec（）

：

从PyQt5.QtWidgets导入QApplication
从MainWindow导入MainWindowApp
app=QApplication（sys.argv）
mainWindow=MainWindowApp（）
sys.exit（app.exec#（））#我想这是因为Cython仍然默认将代码解释为Python2。我猜将语言级别设置为3也会起作用（因为
exec
将不再是一个语句）@DavidW它可能是，但正式的函数是app.exec_（），尽管如图所示，app.exec（）也是允许的。IMHO使用exec_u3;（）并避免兼容性problems@eyllanesc老兄编译后我怎么能运行这些文件@sayreskabir Cython不会生成一个可以自己执行的应用程序，而是生成一个必须导入的库。我建议你调查一下Cython是什么，它是做什么的，它的作用是什么，这样你就知道你必须做什么来执行你的应用程序
