运行JDK自解压.bin文件时遇到python子进程

Question

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

我打开的shell调试

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

输出低于

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

我还通过捕获了bin文件的自提取脚本

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，我想有些环境并没有传递到python中，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

Answer 1

这个线程实际上回答了这个问题：

子流程上的非阻塞读取。python 中的PIPE

它确实解决了我的问题。
