我安装了JSON for PERL，命令如下：
sudo perl -MCPAN -e 'install JSON'但是我不能使用它，use JSON;导致错误：
无法在@INC中找到JSON.pm（您可能需要安装JSON模块）

错误消息中@INC的路径列表表明您正在尝试使用系统perl，但您已经安装了由perlbrew管理的perl版本的模块。
你需要确保你运行的脚本是正确版本的perl。
最有可能的原因是你有一个shebang行
#!/usr/bin/perl。将其更改为#!/usr/bin/env perl以搜索$PATH中的perl。或者，将其更改为perlbrew安装的perl版本的完整路径。e3bfsja22#
您已经为不同的perl示例安装了该模块，而不是您尝试使用它的那个示例。
和
我看到您正在使用
perlbrew，因此在运行命令之前切换到适当的示例应该足够简单顺便说一下，
perl -MCPAN -e 'install JSON'最好写成cpan JSONlf3rwulv3#
问题来了：
Perl/5.18perl-5.16.0你有两个不同版本的perl在运行。我建议你需要
sudo perl -MCPAN -e 'install JSON'使用你在脚本中使用的路径。（或者改变你的脚本指向另一个二进制文件）axkjgtzd4#
试试这个;它应该解决这个问题。
