以下代码在我的IDE(PyScripter)中运行正常,但它不会在它之外运行。当我进入计算机然后python26并双击该文件(在这种情况下为.pyw)它无法运行。我不知道为什么会这样做,有人可以请一些亮点吗?
这是在Windows 7 BTW中。
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()
修改
我尝试在命令行中导入模块并收到以下警告。

我尝试了McSmooth所说的并获得了以下输出。

除非你一直在搞乱你的标准库,否则你的python路径上的某个地方似乎有一个名为threading.py
的文件正在取代标准库。尝试:
>>>import threading
>>>print threading.__file__
并确保它是python lib目录中的那个(它应该是C:\python26\lib
)。如果它不是正在导入的正确文件,那么您必须将伪造的文件重命名为其他文件。如果是正确的文件,请尝试:
>>>threading.Thread
并查看是否在REPL中抛出异常。
这很奇怪。在我的系统上,它给出了源文件的名称。要么保存为文件,要么在命令行运行以下代码来查找它。
import os.path as op
import sys
files = (op.join(path, 'threading.py') for path in sys.path)
print filter(op.exists, files)

您很可能需要调整PYTHONPATH;这是Python用于查找模块的目录列表。另请参阅 How to add to the pythonpath in windows 7? 。
答案 2 :(得分:1)
从Windows命令shell通过输入python二进制文件进入python shell(你应该得到像'&gt;&gt;&gt;'这样的东西)。在这里输入 import matplotlib (您尝试导入的包名称),如果您收到错误,例如 ImportError:没有名为matplotlib的模块,这意味着Matthew F建议您需要更新您的PYTHONPATH(在用户特定的环境或Windows系统环境中)否则发布运行脚本时收到的错误消息。
