Neovim配置Perl支持问题

发表于 更新于

Neovim 将部分功能交给 provider 方式支持，具体技术细节参见：Provider-Neovim docs, 对于python, ruby, node.js和clipboard等配置均比较完美。

问题描述

出现问题的是perl的配置，在我的Thinkpad T490 上发现检查Neovim的健康时无法检测到perl，但是确实已经装上perl了，根据 Provider-Neovim docs 的配置，其他的支持均没有问题，而perl出现警告：

:checkhealth provider-perl

Perl provider (optional) ~
- WARNING "Neovim::Ext" cpan module is not installed
  - ADVICE:
    - See :help |provider-perl| for more information.
    - You may disable this provider (and warning) by adding `let g:loaded_perl_provider = 0` to your init.vim
- WARNING No usable perl executable found

反复安装模块Neovim::Ext

sudo cpanm -n Neovim::Ext

Neovim::Ext is up to date. (0.06)

上述命令无论有没有-n选项都会出现这个提示，不加sudo也是这个提示，这误让我认为我已经安装好模块Neovim::Ext !!

卸载模块Neovim::Ext

sudo cpanm -U Neovim::Ext

!Neovim::Ext is not found in the following directories and can't be uninstalled.

 /usr/lib/perl5/5.40/site_perl
 /usr/share/perl5/site_perl

这条卸载命令让我意识到，我的系统中其实没有正确安装模块Neovim::Ext，同时新版的Neovim对于在.zshrc中设置的路径方式不再依赖！其实它现在可以直接运行sudo的命令了。

重新安装模块Neovim::Ext

Fetching https://www.cpan.org/authors/id/J/JA/JACQUESG/Neovim-Ext-0.06.tar.gz ...OK

运行完这条命令，则模块Neovim::Ext重新安装成功，再启动nvim运行:checkhealth provider.perl 便得到下述内容：

:checkhealth provider-perl

总结

这个问题困扰了我一整天，因为总觉得这不应该是一个重大问题，但是两台电脑几乎配置一样，但笔记本上总是不能解决。此次计算机事故，应当牢记遇到问题一般重装程序或模块，同时使用默认配置就可以解决问题。但是，此次没有解决问题的主要原因是对cpanm不够熟悉！所以在cpanm --help后，获取其详细使用规则后就解决了问题。
