运行 JDK 自解压 .bin 文件卡在 python 子进程中

Question

我试图通过 python 子进程运行 JDK 自解压 .bin 文件，

这里是代码

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

运行卡住，输出如下：

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

bin文件可以在终端独立运行

我通过

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

Checksumming...

+ umask 022

Extracting...

+ javahome=jdk1.6.0_45

我还通过

捕获了bin文件的自解压脚本

head -145 jdk-6u45-linux-i586.bin

从脚本和调试日志中，我可以看到它只是停留在提取脚本的第 74 行

echo "Extracting..."
./$outname

完整脚本如下：

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

这个帖子实际上回答了这个问题：

Non-blocking read on a subprocess.PIPE in python

它确实解决了我的问题。
