Question

我正在尝试使用此tutorial开始开发Firefox插件，但会出现以下问题

(c:\addon-sdk-1.15) C:\Users\Khaled\my-addon>cfx run

我正在使用python 2.6.6并尝试2.7.6同样的问题出现......任何建议??

Answer 1

搜索之后我发现问题是：附加SDK与python 2.7.6不兼容，所以你必须使用python 2.6.6并在使用python 2.6.6时处理这个错误

解决方案：

1-下载cp720

2-解压缩zip文件。

3-将文件cp720.py复制或移动到python编码文件夹中。

 Example: C:\Python26\Lib\encodings\

Answer 2

你的Windows机器是说cfx run生成的文件正在被另一个进程使用，所以我猜你有一个病毒扫描程序或其他程序在创建后立即使用该文件

无法使用cfx run运行我开发的firefox附加组件
