Python modules are installed to #{HOMEBREW_PREFIX}/lib/#{which_python}/site-packages
|
|
so the PYTHONPATH environment variable should include the paths
|
|
#{HOMEBREW_PREFIX}/lib/#{which_python}/site-packages:#{HOMEBREW_PREFIX}/lib
|
|
|
|
Java libraries are installed to #{HOMEBREW_PREFIX}/lib so this path should be
|
|
included in the CLASSPATH environment variable.
