When I try to install a package, I have this error :

Could not find a version that satisfies the requirement Twisted>=16.0.0 (from matrix-synapse==0.27.4) (from versions: ) No matching distribution found for Twisted>=16.0.0 (from matrix-synapse==0.27.4)

So I try to install Twisted : pip install twisted But I get this error :

Could not find a version that satisfies the requirement twisted (from versions: ) No matching distribution found for twisted

I'm working under CentOS6 and python2.7.

Use --verbose option with pip to see exact issue.

Sometimes pip unable to install twisted because of missing library called "libbz"

you can install libbz by below commands.

yum install libbz2
yum install libbz2-devel

Also install bzip 

yum install bzip2
yum install bzip2-devel
