Question

我已经安装了Bloomberg Python API，并将BLPAPI_ROOT设置为VC ++文件夹。

但是，当我导入blpapi时，出现以下错误。

如何摆脱这些错误？

非常感谢您。

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.

我做了两件事来解决类似的问题：

1-我安装了具有以下组件的Microsoft Visual Studio

C ++ / CLI支持
用于桌面的VC ++ 2015.3 v14.00（v140）工具集
用于x86和x64的Visual C ++ MFC
x86和x64的Visual C ++ ATL

2-我将C ++ API \ lib中的.dll文件（在我的情况下为blpapi3_32.dll和blpapi3_64.dll）手动复制到C：\ windows \ system32，系统使用了所有dll文件。

此外，我将C ++ API \ lib中的dll文件复制到C：\ blp \ DAPI中，将新文件替换为旧文件。

Answer 2

请将BLPAPI_ROOT环境变量设置为blpapi C ++ SDK所在的位置。

Answer 3

另一种选择是使用conda，如here和here所述。

如果您使用conda，则无需担心下载C ++ SDK和正确配置BLPAPI_ROOT。在conda-forge频道中，可以使用

conda install -c conda-forge blpapi

无法导入Bloomberg API
