Ruby Sqlite3 installation sqlite3_libversion_numbe

问题:

I'm trying to install the Metasploit framework (unimportant) and bundler is attempting to install sqlite3, which is where it fails consistently. Sqlite3 is installed (executing sqlite3 at the command line brings me into the environment) and is linked using brew link sqlite3 (and adding the --force, for some reason) but bundler install fails each time with this error:

sudo gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.

    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb
Error: Running Homebrew as root is extremely dangerous and no longer supported.
As Homebrew does not drop privileges on installation you would be giving all
build scripts full access to your system.

sqlite3 is missing. Try 'brew install sqlite3',
'yum install sqlite-devel' or 'apt-get install libsqlite3-dev'
and check your shared library search path (the
location where your sqlite3 shared library is located).

I finally managed to solve this by specifying the built-in Mac OS X sqlite library directory on macOS Sierra 10.12.5 (16F73):

$ whereis sqlite3
/usr/bin/sqlite3
# if binary is in /usr/bin then library is typically in /usr/lib
$ gem install sqlite3 -- --with-sqlite3-lib=/usr/lib
Building native extensions with: '--with-sqlite3-lib=/usr/lib'
This could take a while...
Successfully installed sqlite3-1.3.13
Parsing documentation for sqlite3-1.3.13
Done installing documentation for sqlite3 after 0 seconds

I tried specifying the Homebrew library directory but for some reason it didn't work:

$ brew ls --verbose sqlite3
/usr/local/Cellar/sqlite/3.19.3/.brew/sqlite.rb
/usr/local/Cellar/sqlite/3.19.3/bin/sqlite3
/usr/local/Cellar/sqlite/3.19.3/include/msvc.h
/usr/local/Cellar/sqlite/3.19.3/include/sqlite3.h
/usr/local/Cellar/sqlite/3.19.3/include/sqlite3ext.h
/usr/local/Cellar/sqlite/3.19.3/INSTALL_RECEIPT.json
/usr/local/Cellar/sqlite/3.19.3/lib/libsqlite3.0.dylib
/usr/local/Cellar/sqlite/3.19.3/lib/libsqlite3.a
/usr/local/Cellar/sqlite/3.19.3/lib/libsqlite3.dylib
/usr/local/Cellar/sqlite/3.19.3/lib/pkgconfig/sqlite3.pc
/usr/local/Cellar/sqlite/3.19.3/README.txt
/usr/local/Cellar/sqlite/3.19.3/share/man/man1/sqlite3.1
$ gem install sqlite3 -- --with-sqlite3-lib=/usr/local/Cellar/sqlite/3.19.3/lib
This could take a while...
ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.
...

If someone knows how to specify the Homebrew library directory, please let me know because that would provide a little more control over installation (supposedly MacPorts works but I no longer use it).

For anyone curious, here's the full command to install Ruby's Sequel:

gem install sequel mysql sqlite3 -- --with-sqlite3-lib=/usr/lib

And how to convert a Laravel Homestead MySQL database listening on host port 3306 to SQLite from my comment on the question:

sequel mysql://homestead:secret@192.168.10.10:3306/my_database -C sqlite://my_database.sqlite

This worked for me on Mac High Sierra OS 10.13

gem install sqlite3 -- --with-sqlite3-lib=/usr/lib
