pycurl mac 安裝報錯Curl is configured to use SSL,

1、使用安裝第三方插件的方式安裝pycurl：pip3 install pycurl

 

報錯提示如下：

Curl is configured to use SSL, but we have not been able to determine which SSL backend it is using. Please see PycURL documentation for how to specify the SSL backend manually.'

 

 

2、網上通用版解決方式

pip uninstall pycurl
export PYCURL_SSL_LIBRARY=openssl
pip install pycurl


然而對我不管用‘
