Mac OS：/ usr / bin / env：bad interpreter：操作不允许 [英] Mac OS: /usr/bin/env: bad interpreter: Operation not permitted

问题描述

我试图在Mac OS 10.7（Lion）上运行这个脚本，我收到错误：

  $ bbcolors 
 -bash：/ usr / local / bin / bbcolors：/ usr / bin / env：bad interpreter：不允许操作
  

我已经在我的其他Mac上成功运行了这个脚本。只是这个脚本从大胆火球下载并未修改。

我发现这个人有一个非常相似的问题，但接受的答案文件系统在安装时有一个'noexe'选项。我确实对我来说不是这样，因为我刚刚在/ usr / local / bin /中找到它，其他东西在那里工作正常（它也不会从其他地方运行，或者像其他用户包括root） 。

  $哪些bbcolors 
 / usr / local / bin / bbcolors 
 $ ls -l / usr / local / bin / bbcolors 
 -rwxr-xr-x @ 1 nick的员工9751 3月30日19:09 / usr / local / bin / bbcolors 
  

这是一个Perl脚本不是一个编译的二进制文件，不是那么重要。以下是一些额外的信息：

  $ cat / usr / local / bin / bbcolors | head -n 1 
＃！/ usr / bin / env perl 
 $ which perl 
 / usr / bin / perl 
 $ env | grep PATH 
 PATH = / usr / bin：/ bin：/ usr / sbin：/ sbin：/ usr / local / bin：/ usr / X11 / bin 
  pre> 
 
解决方案
您是否碰巧在TextEdit中打开/保存文件？
 
 
 
可以引入文件系统元数据（隔离属性）导致您描述的症状。
 
 
 
尝试：
  xattr -l / usr / local / bin / bbcolors 
  
 
 
 $ b 
和
  xattr -d com.apple.quarantine / usr / local / bin / bbcolors 
  
如果您看到隔离属性。
 
I'm trying to run this script on Mac OS 10.7 (Lion) and I'm getting the error:
$ bbcolors
-bash: /usr/local/bin/bbcolors: /usr/bin/env: bad interpreter: Operation not permitted
I've successfully run this script on other Macs of mine. It's just this script downloaded and unmodified from Daring Fireball.

I found this person with a very similar problem but the accepted answer was that the filesystem had a 'noexe' option on mount.  I'm pretty sure that's not the case for me because I've just got it in /usr/local/bin/ and other stuff in there works fine (it also doesn't run from other places or as other users including root).
$ which bbcolors
/usr/local/bin/bbcolors
$ ls -l /usr/local/bin/bbcolors 
-rwxr-xr-x@ 1 nick  staff  9751 Mar 30 19:09 /usr/local/bin/bbcolors
It's a Perl script not a compiled binary, not that that should matter.  Here's some extra info for what it's worth:
$ cat /usr/local/bin/bbcolors |head -n 1
#!/usr/bin/env perl
$ which perl
/usr/bin/perl
$ env | grep PATH
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

解决方案
Did you happen to open/save the file in TextEdit?

That can introduce filesystem metadata (quarantine attribute) leading to the symptom you describe.

Try:
xattr -l /usr/local/bin/bbcolors
and
xattr -d com.apple.quarantine /usr/local/bin/bbcolors
if you see the quarantine attribute.
