我试图通过 python 子进程运行 JDK 自解压 .bin 文件，
这是代码
proc = subprocess.Popen('./jdk-6u45-linux-i586.bin', cwd=installdir,shell=True, stdout=subprocess.PIPE)
它运行并卡住，输出显示如下：
Install jdk-6u45-linux-i586.bin ...
Unpacking...
bin文件能够在终端中独立运行
我通过以下方式打开 shell 调试
proc = subprocess.Popen('sh -x ./jdk-6u45-linux-i586.bin', cwd=installdir,shell=True, stdout=subprocess.PIPE)
输出如下
Install jdk-6u45-linux-i586.bin ...
Unpacking...
+ PATH=/usr/bin:/bin

我还通过以下方式捕获了 bin 文件的自提取脚本

关于上述问题的任何想法，我猜有些环境没有传入 python，无法弄清楚它是什么。因为 bin 可以直接运行，但不能通过 python 子进程运行
