Centos6でAnsibleを1から2にしたら 「ERROR! Unexpected Exception: 'AnsibleLoader' object has no attribute 'dispose'」

Ansible2をCentOS6にインスト 今までは1.9系でした

yum install python-jinja2-26 --enablerepo=epel
yum --enablerepo=epel-testing install ansible

とりあえずsudo:yesは以下にしとこう become: yes become_user: root

そしてAnsibleを1.9から2.0にしたら以下エラーが出た

[root@ansiblesvr01 ansible]# ansible-playbook -vvv test.yml -i ./hosts --check

どうやらlibyamlが先に入ってないとダメなようで、今回入ってなかったので一度Ansible2をアンインストールして、 そのあとにlibyamlを入れてからAnsible2を入れ直した。 libyamlだけ追加で入れてもダメでした。おそらくライブラリを見てる先が変わってしまってるのかな

ちなみにpython-yamlはAnsibleと依存関係があり同時にインストされます

[root@ansiblesvr001 ansible]# rpm -qa | grep yaml
python-yaml-3.09-3.el6.rf.x86_64
libyaml-0.1.3-4.el6_6.x86_64
