Linux找不到存在的文件

我正在尝试启动并运行Google的Dart语言，但是在运行dart2js时出错。我正在运行Arch Linux，并从AUR 安装了dart-sdk。一些相关的终端输出如下。

% dart2js main.dart   
/usr/local/bin/dart2js: line 7: /usr/local/bin/dart: No such file or directory

可能是因为我运行的是64位操作系统，而飞镖二进制文件是32位吗？

为了执行ELF，二进制linux需要启动一个对ELF进行解码，加载动态库等的程序。该程序称为程序解释器。程序解释器的名称和完整路径由ELF本身编写

例如

 $ file /usr/bin/cheese 
 /usr/bin/cheese: ELF 32-bit LSB executable, Intel 80386

 $ readelf -l /usr/bin/cheese  
 Elf file type is EXEC (Executable file)
 ...
 Program Headers:
 ...
 INTERP         0x000154 0x08048154 0x08048154 0x00013 0x00013 R   0x1
  [Requesting program interpreter: /lib/ld-linux.so.2]
 ...

如果未找到ELF要求的程序解释器，则BASH会得到文件未找到错误，并报告“无此文件或目录”。

正如@poige上面所说，您需要安装基本支持以运行32位应用程序。

是的，默认情况下，Arch x86_64不支持32位应用程序。看到这个：
