python導入子產品失敗_導入lxml子產品導緻PyImport_ImportModule失敗

我想在C++中調用foo。

如果我添加了from lxml import html，但效果很好，當我删除它

Test.py

import os

import sys

import requests

from lxml import html #it will cause failed

def foo():

host = "http://www.baidu.com"

s = requests.session()

res = s.get(host)

return res

C++代碼将在步驟PyImport_ImportModule失敗：

Py_Initialize();

PyRun_SimpleString("import sys");

PyRun_SimpleString("sys.path.append('./')");

PyObject* pModule = PyImport_ImportModule("Test"); //failed

if (pModule == NULL || PyErr_Occurred())

{

PyErr_Print();

}

PyObject* pDict = PyModule_GetDict(pModule);

PyObject *pFunHi = PyDict_GetItemString(pDict, "foo");

PyObject *ret = PyObject_CallFunction(pFunHi,NULL);

Py_DECREF(pFunHi);

Py_Finalize();

錯誤味精：

Traceback (most recent call last):

File "C:\Users\Administrator\Desktop\test\Test\Debug\Test.py", line 4, in

from lxml import html

File "E:\python27\lib\site-packages\lxml\html\__init__.py", line 54, in

from .. import etree

ImportError: DLL load failed: Unable to find the specified module。

如何使用lxml子產品正确？如果pModule == NULL

你應該檢查'pModule == NULL'或者是否發生錯誤。如果有幫助，請參閱我最近的[回複]（http://stackoverflow.com/questions/38745999/embedding-python-in-c-segmentation-fault/38791595#38791595）。 –

您應該驗證lxml是否已正确安裝。 –
