python - 无法使用 cfx run 运行我开发的 Firefox 插件

我正在尝试使用此 tutorial 开始开发 Firefox 插件但出现以下问题

我正在使用 python 2.6.6 并尝试了 2.7.6 出现了同样的问题...有什么建议吗？

Answer 1

搜索后我发现问题是:附加 SDK 与 python 2.7.6 不兼容，因此您必须使用 python 2.6.6 并在使用 python 2.6.6 时处理此错误

解决方案:

1- 下载 cp720

2- 解压 zip 文件。

3- 将文件 cp720.py 复制或移动到您的 python 编码文件夹中。

 Example: C:\Python26\Lib\encodings\
