python之wxPython 和 CEF Python 3

查看 Windows 上 CEF Python 3 中的示例文件。

运行 Python 示例脚本时，它会在 Windows 命令提示符中打开一个调试窗口。

我想知道如何不显示这个？

简单来说:

DEBUG = True -- 没有区别，它只是停止了该窗口内的调试，但该窗口仍然显示。

这是 example.py 文件:

# CEF Python 3 example application. 
 
# Checking whether python architecture and version are valid, otherwise an obfuscated 
# error will be thrown when trying to load cefpython.pyd with a message "DLL load failed".

    raise Exception("Architecture not supported: %s" % platform.architecture()[0])

    if not file.startswith("/") and not file.startswith("\\") and ( 
            not re.search(r"^[\w-]+:", file)): 
        if hasattr(sys, "frozen"): 
            path = os.path.dirname(sys.executable) 
        elif "__file__" in globals(): 
            path = os.path.dirname(os.path.realpath(__file__)) 
        else: 
            path = os.getcwd() 
        path = path + os.sep + file 
        path = re.sub(r"[/\\]+", re.escape(os.sep), path)

请您参考如下方法:

我没看错，但这实际上是我使用 py2exe 的方式。

在 setup.py 文件中，我必须更改:

setup( 
    console=['wxwindow.py'] 
    ,data_files = get_data_files() 
    ,options={"py2exe":{"dll_excludes":dll_excludes, 'optimize': 2}} 
    ,zipfile = "shared.lib" 
) 
 
setup( 
    window=['wxwindow.py'] 
    ,data_files = get_data_files() 
    ,options={"py2exe":{"dll_excludes":dll_excludes, 'optimize': 2}} 
    ,zipfile = "shared.lib" 
) 

所以:

window=['wxwindow.py']
