気流のためにtoxを実行中にエラーが発生しました

Question

気流に寄与しようとしていますが、Ubuntu 16.0.4で毒性が上がることはありません。ケルボで何かが起こっている。

Maybe you forgot to specify a dependency? See also the whitelist_externals envconfig setting.

ないどこでもこれを起動してください。私はすべてのdepsをインストールしたと思う。

Answer 1

scripts/ci/setup_kdc.shはsudoで実行され、sudoは環境変数を消去するため、${KRB5_KTNAME}は定義されていません。

コマンドsudoはtox.iniに使用されているが、（もちろん、それはしていません - sudoはvenvにインストールすべきでないシステムコマンドである。）その仮想環境でそれをtox見つからないコマンドがある必要がありますセクション[testenv]にtox.iniにホワイトリスト：

[testenv] 
whitelist_externals = 
    sudo 

これらはairflowのバグあり、それらをプルリクエストやバグレポートを送ってください。
