I ran pip install pycurl and got crazy error

Apparently pip doesn’t really resolve all of pycurl’s dependencies.
Run apt-cache depends python-pycurl
[code] python-pycurl Depends: python Depends: python Depends: python:any python Depends: libc6 Depends: libcurl3-gnutls Suggests: libcurl4-gnutls-dev Suggests: python-pycurl-dbg Suggests: python-pycurl-doc [/code]
See the Suggests. So run
[code] sudo apt-get install libcurl4-gnutls-dev sudo apt-get install python-pycurl-dbg sudo apt-get install python-pycurl-doc [/code]
Run pip install pycurl, but that still fails due to x86_64-linux-gnu-gcc…

To save you time, do
[code] # upgrade pip if necessary pip install –upgrade pip
# remove current pycurl pip uninstall pycurl
# set PYCURL_SSL_LIBRARY export PYCURL_SSL_LIBRARY=nss
# recompile and install pycurl pip install –compile pycurl [/code]
