[设置Bloomberg Python API时，ImportError _versionhelper

Question

我正在尝试使用Bloomberg Python API进行设置。我一直在关注这个tutorial。我能够成功python -m pip install — index-url=https://bloomberg.bintray.com/pip/simple blpapi，但是当我尝试在Python解释器中运行import blpapi时，出现以下错误。如何解决此错误（想知道是否应该使用Python 3.8来解决此问题）？

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

您需要下载具有与您的C ++库匹配的版本的python blpapi软件包。

在您的情况下，由于您的C ++库是3.13.1.1，因此您可以下载3.13.1 python软件包：

pip install --index-url=https://bloomberg.bintray.com/pip/simple blpapi==3.13.1
