问题


Just installed El Capitan and can't install gem eventmachine 1.0.7. openssl is at 1.0.2a-1. Tried to use --with-ssl-dir but it seems ignored.

Reported it to their github repo as well.

Any suggestions are really appreciated. Thanks.

$ ls /usr/local/Cellar/openssl/1.0.2a-1/include/openssl/ssl.h
/usr/local/Cellar/openssl/1.0.2a-1/include/openssl/ssl.h

$ gem install eventmachine -v '1.0.7' -- --with-ssl-dir=/usr/local/Cellar/openssl/1.0.2a-1/include

$ gem install eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include

You can also set up bundler like this but I think that is superficial

bundle config build.eventmachine --with-cppflags=-I/usr/local/opt/openssl/include



回答2:


When using bundler and homebrew:

$ bundle config build.eventmachine --with-cppflags=-I$(brew --prefix openssl)/include
$ bundle install



回答3:


brew link --force openssl

Then:

gem install eventmachine

It also fixes:

  • gem install taks
  • bundle install
  • rake and rails tasks

P.S. Probably you'll need to remove and run brew install openssl again

The issue happends because Apple had removed openssl from OSX (in El Captain build)




回答4:


gem pristine eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include

pristine removes the old gem and recompiles it.

The cpp flags option allows the compiler to find the openssl headers.

You can also add the version if you like:

gem pristine eventmachine -v '1.0.4' -- --with-cppflags=-I/usr/local/opt/openssl/include

I was trying to install v 1.0.3 and this worked for me.

gem install eventmachine -v '1.0.3' -- --with-cppflags=-I/usr/local/opt/openssl/include

These discussions were very helpful. https://github.com/eventmachine/eventmachine/issues/602




回答6:


If you're installing EventMachine as a dependency of another gem, be sure to specify the correct version when you manually install the gem:

gem install eventmachine -v 1.0.5 -- --with-cppflags=-I$(brew --prefix openssl)/include

Then you can install the gem that you were originally trying to install:

gem install mailcatcher



回答7:


One alternative is to add a bundler config entry for your whole user profile, like this:

cd ~
bundle config build.eventmachine --with-cppflags=-I$(brew --prefix openssl)/include

it'll create a .bundle/config file in your home directory, which is then used in all your projects when you run bundle install.




回答8:


This solved the problem for me:

PKG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig" gem install eventmachine -v "1.0.8"

This worked for me -

    gem install eventmachine -v '1.0.7' -- --debug --backtrace --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib
    Building native extensions with: '--debug --backtrace --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib'
    This could take a while...

    Parsing documentation for eventmachine-1.0.7
    Installing ri documentation for eventmachine-1.0.7
    Done installing documentation for eventmachine after 9 seconds

NOTE:- Before I was able to successfully install this gem, I had to do a few things. These might apply to you, so listing them here -

1.) got off the corporate-VPN OR you might have to turn ON proxy settings

2.) PKG_CONFIG_PATH was set to -

echo $PKG_CONFIG_PATH
/usr/local/opt/openssl/lib/pkgconfig

3.) had to add the following to $PATH in bash_profile (in my case ~/.zshrc)

export PATH="/usr/local/opt/openssl/bin:$PATH"

4.) Also note, that contrary to some answers I got in this SO post, and also this thread on github-eventmachine, I was not able to install eventmachine

gem install eventmachine -v '1.0.7' -- --debug --backtrace --with-cppflags=-I/usr/local/include --with-ldflags=-L/usr/local/lib
Fetching: eventmachine-1.0.7.gem (100%)

ERROR:  Error installing eventmachine:
    ERROR: Failed to build gem native extension.

It seems /usr/local/opt/openssl/include is the right location and not /usr/local/include when specifying the openssl location.
