Question

我正在尝试在我自己的PyCharm项目中复制/合并this tutorial中的代码。

我有两个文件tempconv.py和mainwindow.py，其中包含相同的代码。

前一个文件位于Users/some_user/Documents/Coding/Qt/firstGUI 后一个文件位于/Users/some_user/Documents/Coding/Python/CV-generator 代码中引用的文件tempconv.ui存在于两个文件夹中。

这是文件中的代码。这些文件是相同的，但mainwindow.py包含在我的PyCharm项目中，而tempconv.py则不包括在内。

import sys
from PyQt4 import QtCore, QtGui, uic

form_class = uic.loadUiType("tempconv.ui")[0]                 # Load the UI

class MyWindowClass(QtGui.QMainWindow, form_class):
    def __init__(self, parent=None):
        QtGui.QMainWindow.__init__(self, parent)
        self.setupUi(self)
        self.btn_CtoF.clicked.connect(self.btn_CtoF_clicked)  # Bind the event handlers
        self.btn_FtoC.clicked.connect(self.btn_FtoC_clicked)  #   to the buttons

    def btn_CtoF_clicked(self):                  # CtoF button event handler
        cel = float(self.editCel.text())         #
        fahr = cel * 9 / 5.0 + 32                #
        self.spinFahr.setValue(int(fahr + 0.5))  #

    def btn_FtoC_clicked(self):                  # FtoC button event handler
        fahr = self.spinFahr.value()             #
        cel = (fahr - 32) * 5.0 / 9              #
        self.editCel.setText(str(cel))           #

app = QtGui.QApplication(sys.argv)
myWindow = MyWindowClass(None)
myWindow.show()
app.exec_()

有4种情况，其中一种情况失败。

                 Run in PyCharm         Run in Terminal
mainwindow.py    Error                  Succes
tempconv.py      Succes                 Succes

错误是：

Traceback (most recent call last):
  File "/Users/some_user/Documents/Coding/Python/CV-generator/mainwindow.py", line 4, in <module>
    form_class = uic.loadUiType("tempconv.ui")[0]                 # Load the UI
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyQt4/uic/__init__.py", line 208, in loadUiType
    winfo = compiler.UICompiler().compileUi(uifile, code_string, from_imports, resource_suffix)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyQt4/uic/Compiler/compiler.py", line 140, in compileUi
    w = self.parse(input_stream, resource_suffix)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PyQt4/uic/uiparser.py", line 974, in parse
    document = parse(filename)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 1182, in parse
    tree.parse(source, parser)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 647, in parse
    source = open(source, "rb")
IOError: [Errno 2] No such file or directory: 'tempconv.ui'

如果我在终端中运行python /Users/some_user/Documents/Coding/Python/CV-generator/mainwindow.py则没有问题。

另外，这个：

Machine:~ some_user$ ls /Users/some_user/Documents/Coding/Python/CV-generator
README.md     functions.pyc mainwindow.py scratch.json  tex
functions.py  input.json    read-in.py    tempconv.ui

显示文件在那里。

如何找到问题的原因并解决问题？

相同的Python文件，一个运行，另一个抛出“找不到文件”错误
