ERROR: Cannot install pyspider==0.3.0, pyspider==0.3.1, pyspider==0.3.10, pyspider==0.3.2, pyspider==0.3.3, pyspider==0.3.4, pyspider==0.3.5, pyspider==0.3.6, pyspider==0.3.7, pyspider==0.3.8 and pyspider==0.3.9 because these package versions have conflicting dependencies.
The conflict is caused by:
pyspider 0.3.10 depends on pycurl
pyspider 0.3.9 depends on pycurl
pyspider 0.3.8 depends on pycurl
pyspider 0.3.7 depends on pycurl
pyspider 0.3.6 depends on pycurl
pyspider 0.3.5 depends on pycurl
pyspider 0.3.4 depends on pycurl
pyspider 0.3.3 depends on pycurl
pyspider 0.3.2 depends on pycurl
pyspider 0.3.1 depends on pycurl>=7.19
pyspider 0.3.0 depends on pycurl>=7.19
To fix this you could try to:
loosen the range of package versions you've specified
remove package versions to allow pip attempt to solve the dependency conflict
