使用PyCharm 4.0.5的Python发生编译错误

Question

The reason for me asking the question here is that I did not find a solution elsewhere. I'm having the following error with my PyCharm 4.0.5 program while trying to run a Python script. It was working fine the one day and when I tried using it this afternoon I got the following error after tying to run a program which I am 100% has no errors in it. In the message box I got the following error:

Failed to import the site module
Traceback (most recent call last):
  File "C:\Python34\lib\site.py", line 562, in <module>
    main()
  File "C:\Python34\lib\site.py", line 544, in main
    known_paths = removeduppaths()
  File "C:\Python34\lib\site.py", line 125, in removeduppaths
    dir, dircase = makepath(dir)
  File "C:\Python34\lib\site.py", line 90, in makepath
    dir = os.path.join(*paths)
AttributeError: 'module' object has no attribute 'path'

Process finished with exit code 1

I have never seen an error of this kind and don't know where to start tackling this problem.

Any feedback will be greatly appreciated!

The code looks like the following, and I seem to have forgotten to mention that it gives me the exact same error for every single .py script on my computer.

import turtle
wn = turtle.Screen()
alex = turtle.Turtle()


def hexagon(var):
    for i in range(6):
        alex.right(60)
        alex.forward(var)


def square(var):
    for i in range(4):
        alex.forward(var)
        alex.left(90)


def triangle(var):
    for i in range(3):
        alex.forward(var)
        alex.left(120)


def reset():
    alex.clear()
    alex.reset()
x = True
while x:
    alex.hideturtle()
    choice = input("""
    Enter the shape of choice:
    a. Triangle
    b. Square
    c. Hexagon
                    """)
    if choice.lower() == "a":
        length = input("Enter the desired length of the sides:  ")
        triangle(int(length))
        restart = input("Do you wish to try again? Y/N  ")
        if restart.lower() == "n":
            x = False
        else:
            reset()
    if choice.lower() == "b":
        length = input("Enter the desired length of the sides:  ")
        square(int(length))
        restart = input("Do you wish to try again? Y/N  ")
        if restart.lower() == "n":
            x = False
        else:
            reset()
    if choice.lower() == "c":
        length = input("Enter the desired length of the sides:  ")
        hexagon(int(length))
        restart = input("Do you wish to try again? Y/N  ")
        if restart.lower() == "n":
            x = False
        else:
            reset()
print("Thank you for using your local turtle services!")

您必须具有一个名为os.py的python文件，而不是“真正的” os模块，该文件将被导入。
