Python httplib2.SSLHandshakeError:[SSL:证书\u验证\u失败]证书验证失败（\u SSL.c:581）

我正在尝试使用oath2通过Anaconda Python 2.7.6连接到LinkedIn。 我不知道怎么了

我是否需要向my/Users/davidlaxer/anaconda/lib/python2.7/site-packages/httplib2/cacerts.txt添加证书

以下是错误：

/Users/davidlaxer/anaconda/bin/python2 /Users/davidlaxer/workspace/LinkedInGraph/Authorization.py

Process finished with exit code 1

我还尝试了使用python linkedin软件包获取凭证
