sqlite3 gem fails to install

问题

I'm trying to install the "sqlite3-ruby" gem (or the "sqlite3" gem) on OS X 10.6. I'm using ruby-1.9.2 and I currently get the following:

 $ sqlite3 --version
3.7.4
 $ sudo gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3-ruby:

Gem files will remain installed in /Users/folken/.rvm/gems/ruby-1.9.2-head/gems/sqlite3-1.3.3 for inspection.

The following is the results of which & whereis, and the sqlite3.h is located in /opt/local/include:

 $ which sqlite3
/opt/local/bin/sqlite3
 $ whereis sqlite3
/usr/bin/sqlite3

I've tried passing in the following as well:

sudo gem install sqlite3 -- --with-sqlite3-include /opt/local/include --with-sqlite3-lib /opt/local/lib
sudo gem install sqlite3 -- --with-sqlite3-dir /opt/local/bin

which results in the following:

ERROR:  Error installing sqlite3-ruby:
    ERROR: Failed to build gem native extension.

Also under /Users/folken/.rvm/gems/ruby-1.9.2-head/gems: sqlite-ruby-2.2.3 sqlite3-1.3.3

Under RVM I have ruby-1.8.7 and the sqlite3 gem loads fine on that, but after much googling I have not found a solution that works for me. Any help is greatly appreciated (even if it involves manual installation / hackery to get working).

回答1:

I had an almost similar problem as you where I had sqlite3 installed and yet the sqlite3 gem would not install. I was seeing an error message as follows,

user-name-rajas-macbook-pro:rails3 user-namer$ gem install sqlite3
Building native extensions.  This could take a while...
    ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.

checking for sqlite3.h... yes
checking for sqlite3_libversion_number() in -lsqlite3... no
sqlite3 is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).

Here is what worked for me

gem install sqlite3 -- --with-sqlite3-dir=/opt/local

回答2:

I was following the Rails3 in Action book with rvm using ruby 1.9.2.p180 and rails 3.1.0.rc6 using Mac OS X 10.5.8 (Leopard) and when I ran:

rake cucumber:ok

I got:

Please install the sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (can't activate sqlite3 (~> 1.3.4, runtime), already activated sqlite3-1.3.3. Make sure all dependencies are added to Gemfile.) 

I then did:

gem install sqlite3 -- --with-sqlite3-dir=/opt/local

Followed by:

bundle install

Hopefully, I will find my own answer on the Internet when sqlite 1.3.5 is required.

回答3:

Sounds like you haven't installed XCode.

回答4:

For osx, make sure you have Xcode installed and you have accepted the terms. For me, I had not agreed to the terms (for whatever reason, perhaps Xcode was recently installed or updated on my computer).

1. Open Xcode
2. If a pop up appears then agree to the terms (if you do not get a pop up then you probably have already accepted the terms).
