I can not install matplotlib. I get an error message:
error: Failed to download any of the following: [‘https://downloads.sourceforge.net/project/freetype/freetype2/2.6.1/freetype-2.6.1.tar.gz’, ‘https://download.savannah.gnu.org/releases/freetype/freetype-2.6.1.tar.gz’, ‘https://download.savannah.gnu.org/releases/freetype/freetype-old/freetype-2.6.1.tar.gz’]. Please download one of these urls and extract it into ‘build/’ at the top-level of the source repository.
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
