Java is installed, in listing, but execution produces "./java: No such file or directory"
提问by thejartender
I just ran the script below and it fetches and unpacks the JDK into the correct location. Problem is that every javacommand (as copied to /urs/bin) gives errors. I then double check by going into the JDK install directory by means of cd(I am now in JDK/bin) and type : ./java -versionand get : ./java: No such file or directory, but javais there! ls -lon the JDK shows that all javaclients are inside the bin.
我刚刚运行了下面的脚本，它提取 JDK 并将其解压缩到正确的位置。问题是每个java命令（复制到/urs/bin）都会出错。然后我通过进入 JDK 安装目录cd（我现在在 JDK/bin 中）并输入 :./java -version并获取 : 来仔细检查./java: No such file or directory，但是java在那里！ls -l在 JDK 上显示所有java客户端都在bin 内。

You're running on a 64bit system without a 32bit runtime environment.
您在没有 32 位运行时环境的 64 位系统上运行。
Assuming ubuntu/debian issue:
假设 ubuntu/debian 问题：
apt-get install libc6-i386
Or you should install the 64bit version of the package into this VM (which is probably the best solution).
或者您应该将 64 位版本的软件包安装到此 VM 中（这可能是最好的解决方案）。
The error message is coming from the run-time linker/loader. if you do a readelf -l javayou will find a line like:
错误消息来自运行时链接器/加载器。如果你这样做，readelf -l java你会发现一行：
[Requesting program interpreter: /lib/ld-linux.so.2]
Which is what you expect for a 32bit application, and you probably don't have the 32bit environment installed - check with an ls -l of that program interpreter.
这是您对 32 位应用程序的期望，并且您可能没有安装 32 位环境 - 检查 ls -l program interpreter。
and example for a 64bit program would look like (your system may vary):
64 位程序的示例如下（您的系统可能会有所不同）：
[Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]
If this is not the case, and you do have the 32bit libc installed, you can try an ldd java, which will give a listing like:
如果不是这种情况，并且您确实安装了 32 位 libc，则可以尝试一个ldd java，它会给出如下列表：
linux-gate.so.1 => (0xf76ef000)
libpthread.so.0 => /lib32/libpthread.so.0 (0xf76b3000)
libjli.so => /home/bubba/java/jdk1.7.0_02/bin/./../jre/lib/i386/jli/libjli.so (0xf769f000)
libdl.so.2 => /lib32/libdl.so.2 (0xf7699000)
libc.so.6 => /lib32/libc.so.6 (0xf751f000)
/lib/ld-linux.so.2 (0xf76f0000)
if there are lines saying not foundthen you should add pagkages providing that, but as you can see from this lddall the dependencies are core libraries that should be present on practically all linux systems.
如果有台词，not found那么你应该添加提供它的 pagkages，但正如你所看到的，ldd所有的依赖项都是核心库，几乎所有的 Linux 系统都应该存在。

I was getting the
我得到了
bash: /usr/bin/java: No such file or directory
bash: /usr/bin/java: 没有那个文件或目录
The issue was I installed the i586version of Java on a x86_64Debian.
问题是我i586在x86_64Debian上安装了Java 版本。
The fix: I removed it and install the x64version of Java. Everything is working fine now.
修复：我删除了它并安装了x64Java 版本。现在一切正常。
