对'/usr/local/share/man/man3‘没有写权限

Question

我正在使用Linux机器，从Cpan安装JSON Perl模块时出现YAML not installed错误。任何帮助都是非常值得感谢的。

cpan[1]>install JSON

当我尝试安装YAMl时，我得到了这个错误。

Answer 1

'YAML' not installed, will not store persistent state是无害的。

至于没有权限写入/usr/local/share/man/man3，有什么理由相信这是不正确的吗？

如果您具有root访问权限，您是否按照错误消息中的说明进行操作？启动cpan，执行以下命令：

o conf make_install_make_command 'sudo make'
o conf commit

如果您没有root访问权限，您是否在询问如何将模块安装到任意目录？我会使用perlbrew在您的主目录中安装一个perl。

Answer 2

您是否以普通用户身份运行cpan？没有sudo或root访问权限？这可能就是为什么。
