一直想爬虫，前一段时间终于吧python大概的学了一下，想着终于可以上手爬虫了，不成想一路坎坷，各种坑，先大概的总结下目前遇到的问题以及处理方案（也有没找到解决方案的）。
-
ImportError: pycurl: libcurl link-time ssl backend (openssl)- 找到的解决方案1：说来奇怪这个方法至今不能解决我的问题 ，我的电脑是Mac 10.13.1的系统
-
pip uninstall pycurl#卸载掉之前安装的但是,有的需要在这个命令前加上sudo -H用来增加权限 - 继续执行
export PYCURL_SSL_LIBRARY=openssl - 再次安装
pip install pycurl
- 方案二：貌似对我有用实际没有
就是在方案一中的第二步后边改为下边三步
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include
pip install pycurl --compile --no-cache-dir - 方案三：
pip3 uninstall pycurl
pip3 install --compile --install-option="--with-openssl" pycurl
有的人说以上操作完成后重启电脑就会好，我重启电脑，再次
pyspider，依旧有问题
