When I install pyspider,the following error occurred.

Complete output from command python setup.py egg_info: Using curl-config (libcurl 7.54.0) Traceback (most recent call last): File "", line 1, in File "/private/tmp/pip-install-Ei7TZj/pycurl/setup.py", line 913, in ext = get_extension(sys.argv, split_extension_source=split_extension_source) File "/private/tmp/pip-install-Ei7TZj/pycurl/setup.py", line 582, in get_extension ext_config = ExtensionConfiguration(argv) File "/private/tmp/pip-install-Ei7TZj/pycurl/setup.py", line 99, in init self.configure() File "/private/tmp/pip-install-Ei7TZj/pycurl/setup.py", line 316, in configure_unix specify the SSL backend manually.''') main.ConfigurationError: Curl is configured to use SSL, but we have not been able to determine which SSL backend it is using.

Maybe you can run: apt-get install libcurl4-openssl-dev and then have a try again.

I had to set the SSL library before installing (Mac OS 10.13.6 (17G65)).

export PYCURL_SSL_LIBRARY=openssl
export LDFLAGS=-L/usr/local/opt/openssl/lib
export CPPFLAGS=-I/usr/local/opt/openssl/include
