ImportError:导入LeapPython时DLL加载失败:找不到指定的模块

Question

一些上下文：我目前正在进行一个项目，在PyParrot Mambo无人机和Leap Motion Controller之间进行通信。我遇到的问题是，Leap运动控制器软件只能在python 2.7中工作，而PyParrot Mambo Drone只能在python 3.9中工作。我找到了Leap Motion Controller软件与Python 3.7的绑定。当我试图在Python 3.9中运行适用于Python 3.7的Leap Motion代码时，我遇到了一个错误。

以下是用于在Python 3.7中运行the Leap Motion Controller的绑定文件。当我从python 3.9中提供的文件夹运行Sample.py文件时，我得到了以下错误：

(py39) C:UsersJoginder BassiDownloadsLeapC-Python3.7>python Sample.py

During handling of the above exception, another exception occurred:

如果有人能澄清在python 3.7到3.9之间进行了哪些更改，这些更改将导致这些错误，并可能修复使python 3.7代码与python 3.9兼容的问题。如果有一个新版本的python 3的Leap Motion软件绑定，那也会很有帮助。

Answer 1

绑定是用SWIG生成的，SWIG不实现Python Stable API，因此您需要为每个Python版本重新构建绑定，以便与Python 3.9一起使用。

本指南是为Python 3.3.0编写的，但应该有助于指导您为Python 3.9重新构建它。

Answer 2

我发现可以在这个GitHub repo中使用Python 3.9绑定(seanschneewiss/RoSeMotion(。我已经在我的项目中测试过了，它似乎运行得很好。还有3.6、3.7、3.8的绑定。
