出于某种原因,我无法使用Tkinter或tkinter模块.在python shell中运行以下命令后

import Tkinter

要么

import tkinter

我收到了这个错误

import Tkinter

要么

import tkinter

可能是什么原因以及我们如何解决它？

我在服务器中运行一个简单的python脚本:

import matplotlib.pyplot as plt
import numpy as np

x = np.random.randn(60)
y = np.random.randn(60)

plt.scatter(x, y, s=20)

out_png = 'path/to/store/out_file.png'
plt.savefig(out_png, dpi=150)

我尝试python example.py在这个安装了matplotlib 1.5.1的服务器中使用该命令失败并显示错误:
