グーグルがコードの品質向上のために作った「バグ予測アルゴリズム」を試してみた

最近はレガシーコードと向き合えなくて逃避ぎみの毎日を送っています
TDDとか興味はあるというか推し進めなきゃいけないんだろうけどなにか他にも説得力があるものはないかなと「バグ予測アルゴリズム」試してみました


gemでインストールが必要みたいなのでrubyを入れるところから始めます

rubyのインストール

gemを使うのでrubyを入れます
新しいrubyはgemも一緒にはいるっぽいので新しいのを入れます

依存モジュールのインストール

~~~
yum -y install zlib-devel
yum -y install openssl-devel
yum -y install mysql-devel
~~~

rubyをソースからインストール

~~~
cd /usr/local/src
wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p0.tar.gz

tar xfz ruby-1.9.2-p0.tar.gz
cd ruby-1.9.2-p0

./configure
make
make install
~~~

入ったかどうかの確認
~~~
ruby -v
gem -v
~~~

bugspotsのインストール

~~~
gem install bugspots

gitが入っていないと動かないみたい??
~~~
yum install git

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Setting up Install Process
No package git available.
Nothing to do
~~~

あれ、git、yumで入らんかったっけ??
仕方ないのでepelを使って入れる

~~~
yum install git –enablerepo=epel

入ったので再び叩いてみる
