我们不知道为什么会出现这个错误？ check-dependency.pl 文件存在于脚本文件夹中...
答案1
我的预感：./check-dependencies.pl从 开始#!/usr/local/bin/perl。将第一行更改为#!/usr/bin/perl.
说明：当你运行一个程序时，内核将文件加载到内存中并执行它。然而，许多可执行文件（实际上是大多数）不能直接执行，而是需要另一个程序，即加载程序：
- 大多数二进制程序都是动态链接的，并且必须由动态链接器（
/lib/ld-linux.so.2对于 32 位程序，/lib64/ld-linux-x86-64.so.2对于 64 位程序）负责加载程序请求的库。 - 脚本必须由其解释器加载。
内核识别脚本是因为它以舍邦线。 shebang 行是脚本的第一行，由字符组成#!，后跟解释器的完整路径。 （可选）该行还可以包含一个空格，后跟一个传递给解释器的参数。
例如，如果脚本以 开头#!/usr/local/bin/perl -w，那么当内核被告知执行该脚本时，它会执行/usr/local/bin/perl -w /path/to/script。如果它无法执行/usr/local/bin/perl，您会收到一条错误消息。由于内核只能报告错误代码而无法报告其他信息，因此如果脚本不存在或解释器不存在，则来自内核的信息是相同的。
在这种情况下，某些 shell 会仔细检查错误情况，并在脚本存在但内核报告“找不到文件”时打印不同的消息，例如“错误的解释器”。但是 Ubuntu ( ) 上的默认脚本 shell/bin/sh是 Dash，该 shell 旨在快速执行脚本，并且没有像这样的额外便利功能。所以你会得到简单的“文件未找到”报告。
许多 Perl 脚本都以 开头#!/usr/local/bin/perl，这是大多数非 Linux 安装上 Perl 的路径。您可能会发现在您的计算机上创建它很有帮助 - 使其成为 的符号链接/usr/bin/perl，并在您使用它时对其他解释器执行相同的操作。
cd /usr/local/bin
ln -s ../../../bin/bash ../../bin/perl ../../bin/python ../../bin/ruby .
当您编写脚本时，可以通过编写像 这样的 shebang 行来避免此问题#!/usr/bin/env perl。仅当您不将参数传递给解释器时才能完成此操作。看为什么使用“#!/usr/bin/env NAME”而不是“#!/path/to/NAME”作为我的 shebang 更好？来讨论这种可能性。
