将py文件转换为exe，找不到现有的PyQt5插件目录

Question

我对phyton很陌生，刚刚完成了我的第一个应用程序。现在，我正在尝试将.py文件编译为似乎无法正常工作的.exe购买。我到处都在寻找解决方案，但我似乎找不到。

当我运行此命令时：pyinstaller gui.py

出现此错误：

我的路径变量：

C:\Users\Ivo\Anaconda3;C:\Users\Ivo\Anaconda3\Library\mingw-w64\bin;C:\Users\Ivo\Anaconda3\Library\usr\bin;C:\Users\Ivo\Anaconda3\Library\bin;C:\Users\Ivo\Anaconda3\Scripts;C:\Users\Ivo\AppData\Local\Programs\Python\Python36-32\Scripts\;C:\Users\Ivo\AppData\Local\Programs\Python\Python36-32\;C:\Users\Ivo\AppData\Local\Microsoft\WindowsApps;C:\Users\Ivo\AppData\Roaming\Composer\vendor\bin;C:\Users\Ivo\AppData\Local\atom\bin;C:\scrcpy-windows-v1.0\adb.exe;D:\xampp2\php;C:\Users\Ivo\AppData\Roaming\npm;

如果有人能帮助我/指出正确的方向，我会整天整天解决这个问题。

编辑：

另外，由于我已经重新安装了一些东西来尝试解决此问题。该文件将无法启动，并出现以下错误：

Traceback (most recent call last):
  File "C:\Users\Ivo\Documents\temp\project\gui.py", line 9, in <module>
    from PyQt5 import QtCore, QtGui, QtWidgets
ImportError: DLL load failed: The specified procedure could not be found.

Answer 1

Conda 4.5.11，Python 3.6.4，PyInstaller 3.4

在hooks / qt.py中错误地确定了插件路径。Qt要求在任何其他调用之前先实例化QCoreApplication。

我的qt.py挂钩位于〜\ anaconda3 \ Lib \ site-packages \ PyInstaller \ utils \ hooks \ qt.py中。

我这样编辑它：

    json_str = exec_statement("""
        import sys

        # exec_statement only captures stdout. If there are
        # errors, capture them to stdout so they can be displayed to the
        # user. Do this early, in case PyQt5 imports produce stderr
        # output.
        sys.stderr = sys.stdout

        import json
        from %s.QtCore import QLibraryInfo, QCoreApplication

        # QLibraryInfo isn't always valid until a QCoreApplication is
        # instantiated.
        app = QCoreApplication([])
        paths = [x for x in dir(QLibraryInfo) if x.endswith('Path')]
        location = {x: QLibraryInfo.location(getattr(QLibraryInfo, x))
                    for x in paths}
        try:
            version = QLibraryInfo.version().segments()
        except AttributeError:
            version = None
        print(str(json.dumps({
            'isDebugBuild': QLibraryInfo.isDebugBuild(),
            'version': version,
            'location': location,
        })))
    """ % self.namespace)
