导读：我正在努力让Google的Dart语言启动并运行,但在运行dart2js时出错.我正在运行Arch linux,我从AUR安装了 dart-sdk.一些相关的终端输出位于下方. % dart2js main.dart /usr/local/bin/dart2js: line 7: /usr/local/bin/dart: No such file or directory% cat /u

我正在努力让Google的Dart语言启动并运行,但在运行dart2js时出错.我正在运行Arch linux,我从AUR安装了 dart-sdk.一些相关的终端输出位于下方.

可能是因为我正在运行64位操作系统而飞镖二进制文件是32位吗？

解决方法

为了执行ELF二进制文件,linux需要启动一个解码ELF的程序,加载动态库等.这个程序叫做程序解释器.程序解释器的名称和完整路径是在ELF本身中编写的

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请求的程序解释程序,BASH将收到文件未找到错误并报告“没有此类文件或目录”.

正如@poige上面所说,您需要为运行32位应用程序安装基本支持.
