并且没有提供输出（即使我使用verbosity = 3）。 以下是为python.exe WinMerge设置procmon的屏幕截图 有没有办法调试它挂起的原因？

显然，这些版本之间有很多变化，所以我怀疑是否需要进行简单的更改。以下是一些使升级路径更容易的建议：

  • 尝试运行具有中间版本的应用，以查看它何时开始挂起。这可能会为您提供有关需要更改的内容的线索。此外，您应该在增加版本时开始获取弃用警告。

  • 从runserver_plus尝试django-extensions，可能会获得更多反馈。

  • 请查看this post有关从1.4升级到1.7的信息。

  • Here是the Open edX group目前正在将多个应用从1.4升级到1.8的过程中的一些广泛说明。

我有这个问题。为我解决的是：

function capitalizeFirstLetter(string) {
return string.charAt(0).toUpperCase() + string.slice(1);
}

亲切的问候。
