我已经尝试过 notepad++ 和 eclipse 但即便如此，它还是在第 18 行显示了一个缩进错误。我不知道，为什么它会向我抛出这样的错误......？请帮我。

It is your quotes for example on line:
这是您的报价，例如在线：
self.lineEdit.setText('My Generic Device Name')
try this:
尝试这个：

reactor = QtReactor()

self.verticalLayout = QtGui.QVBoxLayout(self)
self.title = QtGui.QLabel("Qt Simple Device")
font = QtGui.QFont()
font.setPointSize(15)
self.title.setFont(font)
self.title.setAlignment(QtCore.Qt.AlignCenter)
self.verticalLayout.addWidget(self.title)

The row
该行
self.verticalLayout.addWidget(self.lineEdit)
should be on the same level of the other rows.
应该与其他行处于同一级别。
You might be missing it because your editor mixes tabs and spaces.
您可能会错过它，因为您的编辑器混合了制表符和空格。
If you click on "edit" in your own question, you'll see that this row is not correctly indented.
如果您在自己的问题中单击“编辑”，您会看到该行没有正确缩进。
回答by Falmarri
It looks like you're using the wrong single quote mark. You need to use ', not '.
看起来您使用了错误的单引号。您需要使用'，而不是'。
Not sure if this is your problem though.
不确定这是否是您的问题。
回答by sth
In such cases it is usually a good idea to run python with the -tflag:
在这种情况下，使用-t标志运行 python 通常是个好主意：
-t : issue warnings about inconsistent tab usage (-tt: issue errors)
-t ：发出有关制表符使用不一致的警告（-tt：发出错误）
This will help to find indentation problems caused by accidentally used tabs.
这将有助于查找由意外使用的制表符引起的缩进问题。
