python - blpapi导入- “Could not open C++ SDK Library”-非常困惑

Question

尝试使用Bloomberg python API设置PC。我遵循了说明的每个步骤，但是当我最终尝试“导入blpapi”时，始终会遇到问题。下面是日志。任何帮助将不胜感激。
在在线研究了数小时后，我已经执行了以下步骤:

将最新的c++ api安装到c:\ blp \ cppapi目录

将c:\ blp \ cppapi \ lib，c \ blp \ cppapi \ bin和c:\ blp \ cppapi添加到了

路径

将en BLPAPI_ROOT设置为c:\ blp \ cppapi

我什至重新安装了Bloomberg。

不过，我总是遇到相同的错误。看来我无法使python进入硬盘驱动器上的c++ API目录...
提前致谢!

Could not open the C++ SDK library.

Download and install the latest C++ SDK from:

    http://www.bloomberg.com/professional/api-library

If the C++ SDK is already installed, please ensure that the path to the library
was added to PATH before entering the interpreter.

很高兴地报告此问题已解决。
原来，我正在运行 Python 3.8 ，尚不支持。我必须降级到 3.7.9 ，并切换到C++ SDK的“实验版本”，才能正常工作。
希望这也可以帮助其他为此付出努力的人。
