Question

I am trying to install gem install travis to use travis-cli as per reference https://rubygems.org/gems/travis but getting below error.

Tried solution mentioned here https://github.com/ffi/ffi/issues/653 :

brew reinstall libffi
export LDFLAGS="-L/usr/local/opt/libffi/lib"
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
gem install travis

package configuration for libffi is not found "xcrun clang -o conftest -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/universal-darwin16 -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/ruby/backward -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0 -I. -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -D_DARWIN_UNLIMITED_SELECT -D_REENTRANT -g -Os -pipe -DHAVE_GCC_ATOMIC_BUILTINS -iwithsysroot /usr/local/libressl/include conftest.c -L. -L/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib -L. -L /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.Internal.sdk/usr/local/libressl/lib -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.Internal.sdk/usr/local/lib -arch x86_64 -arch i386 -lruby.2.3.0 -lpthread -ldl -lobjc " In file included from conftest.c:1: In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/ruby.h:33: /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/include/ruby-2.3.0/ruby/ruby.h:24:10: fatal error: 'ruby/config.h' file not found #include "ruby/config.h" ^~~~~~~~~~~~~~~ 1 error generated. checked program was: /* begin */ 1: #include "ruby.h" 2: 3: int main(int argc, char *argv) 4: { 5: return 0; 6: } / end */

This will do the trick

sudo gem install -n /usr/local/bin cocoapods -v 1.8.4

Latest CocoaPods 1.10.0 won't work.

Update!

if you want to instal CocoaPods 1.10.0 + you can use HomeBrew and then enter the below in command line

brew install cocoapods
