我正在尝试使用来自PIL的ImageTk.PhotoImage打开图像，但是我一直遇到相同的错误.我有图片，可以看到它在下载时就打开了，然后打开了，但是然后我得到一个错误，它不在那里.

I am trying to open an image with ImageTk.PhotoImage from PIL but I keep hitting the same error. I have the image and can see that it is there when it downloads it, it opens it, but then I get the error that it is not there.

这是错误

Exception in Tkinter callback Traceback (most recent call last): File "C:\Python33\lib\tkinter\__init__.py", line 1475, in __call__ return self.func(*args) File "S:/Projects/xmlParser.py", line 128, in updateSelected self.threadLabelImage.config(text = self.threadImage) File "C:\Python33\lib\tkinter\__init__.py", line 1263, in configure return self._configure('configure', cnf, kw) File "C:\Python33\lib\tkinter\__init__.py", line 1254, in _configure self.tk.call(_flatten((self._w, cmd)) + self._options(cnf)) _tkinter.TclError: image "pyimage1" doesn't exist

我试图将图像应用于图像标签的text属性.这是固定代码.

I was attempting to apply the image to the text attribute of the label instaed of the image. Here is the fixed code.

url = self.threadLinkList[self.y]+'.gif' imageName=self.threadLinkList[self.y][-11:-4]+'.gif' print(imageName) urllib.request.urlretrieve(self.threadLinkList[self.y],imageName) imgfile = Image.open(imageName) imgfile = imgfile.resize((150,150),Image.ANTIALIAS) # img = Image.open(file) print(imgfile) self.threadImage = ImageTk.PhotoImage(imgfile) self.threadLabelImage.config(***image*** = self.threadImage) self.threadImage.image = imgfile
