pycryptoのインストールがCentOS7.3 minimalで失敗する問題の対処

環境

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

結論

gccとpython-develをyumで入れる

調査

デフォルトで入れようとすると以下ログでこける。Cコンパイラがないとのことなのでgccを入れる

[root@localhost ~]# pip install pycrypto
...
    configure: error: in `/tmp/pip-build-EJivFC/pycrypto':
    configure: error: no acceptable C compiler found in $PATH
    See `config.log' for more details
...
Command "/usr/bin/python2 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-EJivFC/pycrypto/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().re
place('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-WsN8Es-record/install-record.txt --single-version-externally-managed --compil
e" failed with error code 1 in /tmp/pip-build-EJivFC/pycrypto/

[root@localhost ~]# yum install gcc

もう1回実行するとPython.hがないと言われる。調べた結果これはpython-develがないためとのことなので入れて解決。

...
