PySide6无法运行

提问者：小点点

我最近安装了PySide 6。我正在运行Ubuntu20.04，试图在VSCode上运行我的代码，并且刚刚运行了：export QT_DEBUG_PLUGINS=1

我收到以下消息：

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

我已卸载并重新安装PySide 6，但仍无法使其运行。我不确定我在这条信息中遗漏了什么，以及我需要做什么。

我尝试运行的代码是：

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”复制并直接从网站粘贴。

有什么想法吗？或者需要更多的信息？

我还没有从qt中找到任何解决方案。io论坛或与此问题相关的任何其他文章。

到目前为止，我遇到了一个工作。我可以直接从终端打开文件。但在尝试运行VSCode时，它仍然不起作用。

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。当将其更改为. ui VSCode时，提示我使用适当的扩展来打开它。我还没有打开它，但我相信这就是我应该看到的。让它在终端打开，而不是VSCode，告诉我这是VSCode没有的东西。

所以我终于让它起作用了。

在我的工作区窗口中，我所要做的就是右键单击该文件，然后在交互窗口中运行当前文件。VSCode提示我下载了一个Jupyter笔记本内核，然后它就工作了！

或者，使用Ctrl Alt N运行代码，而不是Ctrl F5。确保安装了Code Runner扩展。

考虑到该文件在我的终端中工作，我知道它必须是我在VSCode中正在做或没有做的事情。是的，案子结束了。

我花了一段时间专注于我开始学习的这些课程，所以这并不是因为我一直在为这些课程感到压力。我的解决方案是在我试图让matplotlib显示一个我试图运行的图形（第一次使用matplotlib）时出现的，这就是我的工作原理。所以我突然意识到，为了这个代码尝试它，然后砰的一声，它确实以同样的方式工作。

所以，当事情没有按你希望的方式进行时，不要给自己压力。
