私はTravisCIをrun my unit tests for python 2.7, 3.4, 3.5 and 3.6に使用しています。私の.travis.ymlファイルには、- pip install pytest-faulthandlerという行が含まれています.2日前までは私には何の問題もありませんでした。その後、昨日は、明らかな理由もなく、この行はトラヴィスがエラーでcrashに構築引き起こし始めた：Anacondaは、Python 2.7 TravisCIのfaulthandler用のビルドホイールに失敗しました。
The command "pip install pytest-faulthandler" failed and exited with 1 during .
これは、順番に（？アナコンダによって設定された）のgccへの悪い道に由来するようだ：
unable to execute 'x86_64-conda_cos6-linux-gnu-gcc': No such file or directory
下記の詳細なエラーログ。限り、私は私の設定（travis.yml、setup.cfg、setup.py）にこれに影響を与える可能性のある何も変更していないと私が言うことができます。この問題は、python 2.7の場合にのみ発生し、3.4-3.6の場合、travisは問題なく環境を構築します。
誰もがこの問題を経験したかどうか確認するためにオンラインで検索しようとしましたが、運が悪いです。どんな提案/助言も大歓迎です。ありがとう！
トラビスのエラーログは、完全なビルドログはhereです。
