导入blpapi模块时出错

Question

这是我的第一篇文章。我运行以下代码: Win 10 Anaconda with Python 3.6.5 Bloomberg Anywhere

我正在尝试使用Python的blpapi (彭博社专业应用程序接口)。已下载Desktop API包(带有C++库)，下载了blpapi-3.9.1-cp36-cp36m-win_amd64.whl安装程序文件并成功运行。最后，我在用户和环境变量(来自前面在stackoverflow上的查询)中将C:\..\C++API\v3.11.6.1\bin添加到我的路径中：Python 2.7 with Bloomberg API import blpapi failure

我在运行import blpapi时的错误消息：

有人知道问题出在哪里吗？

Answer 1

有着完全相同的问题。可比性问题。

对我来说，解决方案是将python版本回滚到3.7.7 64位

from: 3.8.3 32-bit
to: 3.7.7 64-bit

如果版本是兼容的，那么BLPAPI就可以工作，否则就会失败。

Bloomberg dll文件：

blpapi3_32.dll (version 3.14.3.1)
blpapi3_64.dll (version 3.14.3.1)

这就解决了问题。

Answer 2

解决方案:我安装了微软构建工具2017，并添加了BLPAPI_ROOT路径，如我最初帖子中链接的问题所述。
