とりあえずインストールしてtweepyをpipで入れようとしたらこんなエラーが発生。

# pip3 install tweepy
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting tweepy

Could not find a version that satisfies the requirement tweepy (from versions: )
No matching distribution found for tweepy

少し調べてみると、opensslが入っていないことが原因とのこと。
入れてから再度実行します。

#yum install openssl-devel
# pip3 install tweepy

エラー内容変わらず。

解消法

なんてことは無い、openssl入れてから再度makeし直してaltinstall してあげれば解消します。

# make
# make altinstall
Successfully installed pip-9.0.3 setuptools-39.0.1
# pip3 install --upgrade pip
# pip3 install tweepy

とりあえず、こんなもんで。
