的：

去换成

试试：

问题依旧。
Error install with new version 7.43.0.2 · Issue #526 · pycurl/pycurl
然后看到的办法，和之前自己的：
一样：
<code>➜ x pip uninstall pycurl Skipping pycurl as it is not installed. ➜ x export PYCURL_SSL_LIBRARY=openssl ➜ x export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/opt/openssl/include;pip install pycurl --compile --no-cache-dir Collecting pycurl Downloading https://files.pythonhosted.org/packages/e8/e4/0dbb8735407189f00b33d84122b9be52c790c7c3b25286826f4e1bdb7bde/pycurl-7.43.0.2.tar.gz (214kB) 100% |████████████████████████████████| 215kB 6.0kB/s Installing collected packages: pycurl Running setup.py install for pycurl ... done Successfully installed pycurl-7.43.0.2 </code>
然后继续去：
<code>pipenv install pyspider </code>
即可继续正常安装：
【总结】
（在Mac的pipenv中）安装pyspider期间，会用到pycurl，然后：
安装期间出错：
<code>__main__.ConfigurationError: Curl is configured to use SSL, but we have not been able to determine which SSL backend it is using </code>
或使用期间出错：
<code>ImportError pycurl libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other) </code>
的话，则解决办法都是：
注意，如果用的是pipenv，则需要先进入pipenv环境：
<code>pipenv shell </code>
然后再去运行下面的命令。
<code>pip uninstall pycurl export PYCURL_SSL_LIBRARY=openssl export LDFLAGS=-L/usr/local/opt/openssl/lib;export CPPFLAGS=-I/usr/local/opt/openssl/include;pip install pycurl --compile --no-cache-dir </code>
