英文:
Install perlcritic on macOS Ventura
问题
I'm on macOS Ventura 13.3.1 and I'm trying to get perlcritic working.
perl --version
给出：
This is perl 5, version 36, subversion 0 (v5.36.0) built for darwin-thread-multi-2level...
当我输入：
cpan Perl::Critic
我得到：
Loading internal logger. Log::Log4perl recommended for better loggingReading '/Users/baduker/.cpan/Metadata'Database was generated on Sun, 07 May 2023 10:41:02 GMTPerl::Critic is up to date (1.150).
然而，当我尝试：
perlcritic -1 list.pl
我得到：
zsh: command not found: perlcritic
我还尝试了使用 brew
brew install perlcritic
但是 brew 找不到它，建议使用 perltidy：
Warning: No available formula with the name "perlcritic". Did you mean perltidy?==> Searching for similarly named formulae and casks...==> FormulaeperltidyTo install perltidy, run:brew install perltidy
附加调试信息：
which perl/opt/homebrew/bin/perl
运行 perl -V:installsitebin 给出：
installsitebin='/opt/homebrew/Cellar/perl/5.36.0/bin';
问题： 如何在 macOS 上使 perlcritic 工作？
PS. list.pl 看起来像这样：
#!/usr/bin/perluse strict;use warnings;use Path::Tiny;use autodie;my $dir = path("/tmp"); # /tmpmy $file = $dir->child("test");my $content = $file->slurp_utf8();my $file_handle = $file->openr_utf8();while( my $line = $file_handle->getline() ) {print $line;}

However, when I try:
perlcritic -1 list.pl
I get:
zsh: command not found: perlcritic
I've also tried using brew
brew install perlcritic
But brew can't find it and suggests perltidy:
Warning: No available formula with the name "perlcritic". Did you mean perltidy?==> Searching for similarly named formulae and casks...==> FormulaeperltidyTo install perltidy, run:brew install perltidy
Additional debugging info:
which perl/opt/homebrew/bin/perl
Running perl -V:installsitebin gives:
installsitebin='/opt/homebrew/Cellar/perl/5.36.0/bin';
Question: How do I get perlcirtic working on macOS?
PS. list.pl looks like this:
#!/usr/bin/perluse strict;use warnings;use Path::Tiny;use autodie;my $dir = path("/tmp"); # /tmpmy $file = $dir->child("test");my $content = $file->slurp_utf8();my $file_handle = $file->openr_utf8();while( my $line = $file_handle->getline() ) {print $line;}

根据评论中的反馈，修复很容易。
运行：
perl -V:installsitebin
以确认安装情况。
在我的情况下，perlcritic 被安装了，但出于某种原因，opt/homebrew/Cellar/perl/5.36.0/bin 没有添加到 PATH。
注意：我使用 brew 安装的 perl。
修复方法：
export PATH=$PATH:/opt/homebrew/Cellar/perl/5.36.0/bin/
然后，运行 perlcritic -1 list.pl 会产生如下输出：
No package-scoped "$VERSION" variable found at line 0, column 0. See page 404 of PBP. (Severity: 2)
英文:
Based on the feedback in the comments, the fix is easy.
Run:
perl -V:installsitebin
To confirm the installation.
In my case, perlciritic gets installed, but, for some reason, opt/homebrew/Cellar/perl/5.36.0/bin doesn't get added to PATH.
Note: I use brew perl installation.
The fix:
export PATH=$PATH:/opt/homebrew/Cellar/perl/5.36.0/bin/
Then, running perlcritic -1 list.pl produces, for example:
No package-scoped "$VERSION" variable found at line 0, column 0. See page 404 of PBP. (Severity: 2)
