python - 我的 python 代码不会在我的 IDE 之外运行

Question

以下代码在我的 IDE (PyScripter) 中运行良好，但无法在外部运行。当我进入计算机然后使用 python26 并双击该文件(在本例中为 .pyw)时，它无法运行。我不知道为什么要这样做，任何人都可以解释一下吗？

这是在 windows 7 顺便说一句。

我的代码:

#!/usr/bin/env python
import matplotlib


from mpl_toolkits.mplot3d import  axes3d,Axes3D
import matplotlib.pyplot as plt
from matplotlib import cm
import numpy as np
from numpy import arange, sin, pi
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
from matplotlib.figure import Figure
from matplotlib.ticker import LinearLocator, FixedLocator, FormatStrFormatter

import Tkinter
import sys

class E(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent


        self.protocol("WM_DELETE_WINDOW", self.dest)
        self.main()

    def main(self):
        self.fig = plt.figure()
        self.fig = plt.figure(figsize=(4,4))
        ax = Axes3D(self.fig)



        u = np.linspace(0, 2 * np.pi, 100)
        v = np.linspace(0, np.pi, 100)

        x = 10 * np.outer(np.cos(u), np.sin(v))
        y = 10 * np.outer(np.sin(u), np.sin(v))
        z = 10 * np.outer(np.ones(np.size(u)), np.cos(v))





        t = ax.plot_surface(x, y, z,  rstride=4, cstride=4,color='lightgreen',linewidth=1)




        self.frame = Tkinter.Frame(self)
        self.frame.pack(padx=15,pady=15)

        self.canvas = FigureCanvasTkAgg(self.fig, master=self.frame)

        self.canvas.get_tk_widget().pack(side='top', fill='both')


        self.canvas._tkcanvas.pack(side='top', fill='both', expand=1)



        self.btn = Tkinter.Button(self,text='button',command=self.alt)
        self.btn.pack()

    def alt (self):
        print 9
    def dest(self):
        self.destroy()
        sys.exit()



if __name__ == "__main__":
    app = E(None)
    app.title('Embedding in TK')
    app.mainloop()

我尝试在命令行中导入模块并收到以下警告。

我尝试了 McSmooth 所说的并得到了以下输出。

Answer 1

除非您一直在乱用您的标准库，否则您的 python 路径中似乎有一个名为 threading.py 的文件正在替换标准库。尝试:

>>>import threading
>>>print threading.__file__

并确保它是您的 python lib 目录中的那个(它应该是C:\python26\lib)。如果导入的文件不正确，则必须将假文件重命名为其他名称。如果它是正确的文件，则尝试:

>>>threading.Thread

并查看是否在 REPL 中抛出异常。

更新

这很奇怪。在我的系统上，它给出了源文件的名称。另存为文件或在命令行运行以下代码以找到它。

import os.path as op
import sys

files = (op.join(path, 'threading.py') for path in sys.path)
print filter(op.exists, files)
