Windows 上的 pygal - 无法从 pygal 访问类 [英] pygal on windows - cannot access classes from pygal

问题描述

我有这么短的脚本:

import pygal
if __name__ == '__main__':
    bar_chart = pygal.Bar()

和以下错误:AttributeError: 'module' object has no attribute 'Bar'

and following error: AttributeError: 'module' object has no attribute 'Bar'

你知道出了什么问题吗?我要配置一些额外的路径吗?我正在使用窗户.

Do you have any idea what is wrong? Shall I configure some additional paths? I am using windows.

谢谢

推荐答案

如果你的脚本名为pygal.py，当你import pygal时，它会导入您的脚本，而不是您安装到系统站点包中的 pygal 库.而且您的脚本显然没有名为 Bar 的类.

If your script is named pygal.py, when you import pygal, it's going to import your script, not the pygal library you installed into your system site-packages. And your script obviously doesn't have a class named Bar.

解决方案很简单:将您的脚本重命名为不同的名称.像 pygaltest.py 或 mypygal.py.

The solution is simple: rename your script to something different. Like pygaltest.py or mypygal.py.

并确保查看目录，看看是否有 pygal.pyc 遗留下来，这是 Python 从您的 pygal.py 编译的.如果是这样，您必须删除该文件.

And make sure to look at the directory and see if there's a pygal.pyc left behind, which Python compiled from your pygal.py. If so, you have to delete that file.
