Question

我决定学习使用Add-on SDK开发Firefox附加组件，我正在关注Mozilla网站上的tutorial。当我到达cfx run时，我得到了以下异常（哎呀）：

注意： Firefox版本23.0，附加SDK 1.14，Python 2.6.6，操作系统Windows XP SP3

Answer 1

It's a python (2.6) bug

尝试建议的解决方法或升级到2.7

Answer 2

只是想提一下，使用Python 2.7可能对某些人不起作用。附加SDK的README文件说明“在继续之前，请确保您已安装Python 2.5,2.6或2.7”，因此我最初安装了Python 2.7.6。（请注意，这是附加SDK的1.15版本。）输入cfx run后，我得到了一个类似的（虽然不完全相同）错误消息（可以找到in my bug report）。降级到Python 2.6.6后，我不再收到该错误。实际上，加载项SDK的the Troubleshooting page表示cfx currently expects Python 2.5 or 2.6. Older and newer versions may or may not work.
