PySide6 无法运行 - 编程之家

如何解决PySide6 无法运行

我最近安装了 PySide 6。我正在运行 Ubuntu 20.04 尝试在 VSCode 上运行我的代码刚刚运行：export QT_DEBUG_PLUGINS=1

我收到以下消息：

我已经卸载并重新安装了 PySide 6，但仍然无法让它运行。关于我需要做什么，我不确定该消息中我遗漏了什么。

我试图运行的代码是：

import sys
import random
from PySide6 import QtCore,QtWidgets,QtGui

class MyWidget(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()

        self.hello = ["Hallo Welt","Hei maailma","Hola Mundo","Привет мир"]

        self.button = QtWidgets.QPushButton("Click me!")
        self.text = QtWidgets.QLabel("Hello World",alignment=QtCore.Qt.AlignCenter)

        self.layout = QtWidgets.QVBoxLayout()
        self.layout.addWidget(self.text)
        self.layout.addWidget(self.button)
        self.setLayout(self.layout)

        self.button.clicked.connect(self.magic)

    @QtCore.Slot()
    def magic(self):
        self.text.setText(random.choice(self.hello))

if __name__ == "__main__":
    app = QtWidgets.QApplication([])

    widget = MyWidget()
    widget.resize(800,600)
    widget.show()

    sys.exit(app.exec_())

这只是“创建一个简单的应用程序”，直接从网站上复制粘贴。

关于修复的任何想法？或者需要更多信息？

我还没有从 qt.io 的论坛或任何其他与此问题相关的文章中找到任何解决方案。

编辑

到目前为止，我遇到了一种解决方法。我可以直接从终端打开文件。但是在尝试通过 VSCode 运行时它仍然不起作用。

EDIT2

这可能是 VSCode 扩展问题。 PySide 或 QT 将文件保存在 .ui 中。我的代码在 .py 中。将其更改为 .ui 时，VSCode 提示我输入正确的扩展名以打开它。我还没有打开它，但我相信这是我应该如何看待它。让它在终端中打开，而不是 VSCode，告诉我这是 VSCode 没有的东西。

解决方法

所以！！！！！我终于让它工作了。

在我的工作区窗口中，我所要做的就是右键单击该文件，然后在交互式窗口中运行当前文件。 VSCode 提示我下载了一个 Jupyter notebook 内核，然后就成功了！

或者，使用 Ctrl + Alt + N 运行您的代码，而不是 Ctrl + F5。确保您已安装 Code Runner 扩展。

考虑到该文件在我的终端中运行，我知道它必须是我在 VSCode 中做过或没做过的事情。是的，案件已结。

为了专注于我开始参加的这些课程，我已经放下了一段时间，所以并不是说我一直在为此给自己压力。我的解决方案是因为我试图让 matplotlib 显示我试图运行的图形（第一次使用 matplotlib），这就是它的作用。所以我突然想到要为这段代码尝试一下，然后砰的一声，它确实以同样的方式工作。

所以，是的，当事情没有按照你想要的方式工作时，不要给自己压力。
