Python Bloomberg API（'DLL load failed'）

Question

我的Python版本是2.7.3，操作系統是Windows 7.

我想使用彭博API API庫。具體來說，「導入錯誤blpapi」是我最大的問題。

在this site, 我試着運行支持版本（v3.5.5）和實驗版本（v3.5.3）。 但兩者都不起作用。

寫作IDLE import blpapi， 我不斷收到以下錯誤信息：

Traceback (most recent call last):

File <pyshell#0> , line 1, in <module>

import blpapi 

File C:\Python27\lib\site-packages\blpapi\__init__.py , line 5, in <module>

from .internals import CorrelationId 

File C:\Python27\lib\site-packages\blpapi\internals.py , line 50, in <module>

_internals = swig_import_helper() 

File C:\Python27\lib\site-packages\blpapi\internals.py , line 46, in swig_import_helper

_mod = imp.load_module('_internals', fp, pathname, description) 

ImportError: dll load failed specified module could not found

我怎樣才能解決這個問題？ （我希望導入 'blpapi'）

參照這樣的：Python 2.7 with Bloomberg API import blpapi failure

The ImportError is the result of Bloomberg not being able to find the "blpapi3_32.dll" DLL file. This DLL file can be located under the \bin or \lib folder of Bloomberg's C/C++ library, which is at the same location where you got your Python executable. So go download that library (v3.7.5.1 as of this writing), and have your system's "Path" environment variable include that location. This should resolve the issue.

PS you can access the PATH variable via Start > right-clicking "Computer" > Properties > Advanced System Settings > Advanced (tab) > Environment Variables > look for the "Path" variable under "System variables". Edit this variable to include the location of the DLL file, e.g. if the original Path variable is "C:\Python27\Lib\site-packages\PyQt4", then new Path variable should be "C:\Python27\Lib\site-packages\PyQt4;C:\blp\API\blpapi_cpp_3.7.5.1\bin"
