mac下安裝pyspider出現錯誤如下：

Command “python setup.py egg_info” failed with error code 1 in /private/var/folders/......

緊接著我用了pip3 安裝pycurl出現錯誤如下：

 __main__.ConfigurationError: 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.     ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /private/var/......

最後我嘗試了一些解決辦法，下面這種成功安裝了pycurl：

開啟終端，依次輸入以下命令列：

export PYCURL_SSL_LIBRARY=openssl

export LDFLAGS=-L/usr/local/opt/openssl/lib

export CPPFLAGS=-I/usr/local/opt/openssl/include

pip3 install pycurl

最後安裝pyspider：

pip3 install pyspider

安裝後輸入pyspider all 看看能不能成功啟動

還有就是如果你的python版本是3.7還會遇到關鍵字問題，至少我安裝的時候pyspider沒有修訂它的程式碼，所以我又安裝了python3.6，才成功啟動pyspider
