Pygal模块不工作

Question

在尝试运行具有直方图输出的简单代码时，我始终会得到以下错误：

Traceback (most recent call last):
  File "c:\tmp\die_visual.py", line 1, in <module>
    import pygal
  File "C:\Users\Christopher\AppData\Roaming\Python\Python36\site-packages\pygal\__init__.py", line 33, in <module>
    from pygal.graph.bar import Bar
  File "C:\Users\Christopher\AppData\Roaming\Python\Python36\site-packages\pygal\graph\__init__.py", line 24, in <module>
    from .__about__ import *  # noqa: F401,F403
ModuleNotFoundError: No module named 'pygal.graph.__about__'

我已经将需要pygal的文件移到同一个目录中，并得到了相同的错误。

这是我输入的代码。

import pygal
from die import Die
# Create a D6.
die = Die()

# Make some rolls, and store results in a list.

results = []
for roll_num in range(1000):
    result = die.roll()
    results.append(result)


# Analyze the results
frequencies = []
for value in range(1, die.num_sides+1):
    frequency = results.count(value)
    frequencies.append(frequency)

# Visualize the results.
hist = pygal.Bar()
hist.title = "Results of rolling one D6 1000 times."
hist.x_labels = ['1', '2', '3', '4', '5', '6']
hist.x_title = "Result"
hist.y_title = "Frequency of Result"
hist.add('D6', frequencies)
hist.render_to_file('die_visual.svg')

来自pygal位点

安装 pygal可用于python 2.7和3.2、3.3、3.4、3.5和pypy。

因此，它还没有为python 3.6做好准备。
