macos - 启动 lig​​httpd 时 perl @INC 未完成

问题描述

我正在尝试在我的 iMac（Catalina 10.15.6）上运行 TrinotateWeb（v3.2.1）。它使用轻量级浏览器 lighttpd (v1.4.55)，它是我随 Homebrew 安装的。

启动服务器时，它抱怨在@INC 中找不到 HTML/Template.pm：

Can't locate HTML/Template.pm in @INC (you may need to install the HTML::Template module) 
(@INC contains: 
/Library/Perl/5.18/darwin-thread-multi-2level 
/Library/Perl/5.18 
/Network/Library/Perl/5.18/darwin-thread-multi-2level 
/Network/Library/Perl/5.18

.) at /Applications/Trinotate-v3.2.1/TrinotateWeb/cgi-bin/index.cgi line 15.
BEGIN failed--compilation aborted at 
/Applications/Trinotate-v3.2.1/TrinotateWeb/cgi-bin/index.cgi line 15.

但是，HTML/Template.pm 很好地安装在文件夹中/Users/simon/perl5/lib/perl5。它是使用cpan HTML::Template.

问题似乎源于@INC。

我的 .zshrc 配置文件使用 PERL5LIB 引用上述位置：

PATH="/Users/simon/perl5/bin${PATH:+:${PATH}}"; export PATH;
PERL5LIB="/Users/simon/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}"; export PERL5L$
PERL_LOCAL_LIB_ROOT="/Users/simon/perl5${PERL_LOCAL_LIB_ROOT:+:${PERL_LOCAL_LIB$
PERL_MB_OPT="--install_base \"/Users/simon/perl5\""; export PERL_MB_OPT;
PERL_MM_OPT="INSTALL_BASE=/Users/simon/perl5"; export PERL_MM_OPT;

在终端中，@INC 包含 PERL5LIB 并因此链接 HTML/Template.pm：

我不明白为什么在执行 lighttpd 时@INC 没有列出所有路径作为我上面显示的实际环境？

解决方案

lighttpd exec 直接是你的 CGI（或 FastCGI），所以如果你的脚本是 xxxxx.pl 并且 contains #!/usr/bin/perl，那就是执行的。（更明确地说，不执行 zsh 并且不读取 .zshrc ，正如其他人在评论中所说的那样）

您可以将这些脚本中的第一行更新为 include #!/usr/bin/perl -I...，或者您可以修改 lighttpd.conf 以指定：

setenv.add-environment = ("PERL5LIB" => "...")

https://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_ModSetEnv

您也可以指示 mod_cgi 执行 zsh shell 脚本来执行 perl，但这样做会更慢且效率更低。

cgi.assign = (".pl" => "/home/simon/bin/zsh-bounce-perl")

https://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_ModSetEnv

并让zsh-bounce-perl脚本包含类似

#!/usr/bin/zsh
exec perl "$@"
