Perlbrew 找不到@INC

Question

我认为 perlbrew 已正确安装并使用了正确的 @INC。我切换到 perlbrew。我想要的模块 (String::Approx) 已安装。我在 ~/.bash_profile.

中有来源 ~/perl5/perlbrew/etc/bashrc

但我收到错误 Can't locate String/Approx.pm in @INC :

$ which perl
/Users/kip/perl5/perlbrew/perls/perl-5.33.9/bin/perl
$ perlbrew info
Current perl:

这是我尝试运行我的脚本（为便于阅读而格式化）时出现的特定错误消息。 @INC 系统好像还在搜索中？

Can't locate String/Approx.pm in @INC (you may need to install the String::Approx module)

Answer 1

运行 myscript.pl 因为 ./myscript.pl 似乎正在使用系统 perl (v5.30)。也许该文件中有一个指向系统 perl 的 shebang 行。如果是这种情况，那么调用 ./myscript.pl 将始终引用 shebang 行中指定的程序，而不是 perlbrew 将您的环境设置为什么。

解决方案：

明确使用perl调用脚本

$ perl myscript.pl    # this
$ ./myscript.pl       # and not this

更新您的 shebang 行以使用“当前”perl。其中一项或多项可能有效：
```
#!perl
#!/usr/bin/env perl
```
