Pythonサブプロセスを介してJDK自己抽出.binファイルを実行しようとしていますが、

ここにコードがあります

proc = subprocess.Popen('./jdk-6u45-linux-i586.bin', cwd=installdir,shell=True, stdout=subprocess.PIPE)

実行されてスタックし、以下に示す出力が表示されます。

Install jdk-6u45-linux-i586.bin ...
Unpacking...

binファイルはターミナルで独立して実行できます

シェルデバッグをオンにします

proc = subprocess.Popen('sh -x ./jdk-6u45-linux-i586.bin', cwd=installdir,shell=True, stdout=subprocess.PIPE)

以下のように出力

Install jdk-6u45-linux-i586.bin ...

+ PATH=/usr/bin:/bin

上記の問題についての考えは、Pythonに渡されない環境があると思いますが、それが何であるかを理解できませんでした。ビンは直接​​実行できますが、pythonサブプロセスを介しては実行できません

このスレッドは実際に質問に答えます：

Pythonのsubprocess.PIPEでのノンブロッキング読み取り

そして、それは私の問題を解決します。
