我正在尝试安装 Readline。

（系统是 Linux Mint Mate 18.3，Lubuntu 17.10 也是如此）。

$ zef install Readline

安装过程开始，但随后中止并显示以下消息：

locate libreadline.so给出以下输出：

/lib/x86_64-linux-gnu/libreadline.so.5
/lib/x86_64-linux-gnu/libreadline.so.5.2
/lib/x86_64-linux-gnu/libreadline.so.6
/lib/x86_64-linux-gnu/libreadline.so.6.3

许多发行版，包括 debian/ubuntu 和朋友都鼓励在打包之间进行一定的分离，debian.org 打包文档中的更多信息。

特别是，它们鼓励为某些版本（例如.so.1）分发共享库，这些版本是其他包的依赖项，与“未版本化”分开，这些包.so更通常用于“开发”（在以 结尾的分发包中-dev）。

从上面的文档：

请注意，开发包应包含关联共享库的符号链接，不带版本号。例如：/usr/lib/x86_64-linux-gnu/libfoo.so -> libfoo.so.1

对于 readline，该链接在libreadline-dev包中，可以安装在 mint/ubuntu/debian 类型的系统上，如下所示：sudo apt-get install libreadline-dev

Perl 6 NativeCall文档也讨论了这个：

如果你写 native('foo') NativeCall 将在类 Unix 系统下搜索 libfoo.so（在 OS X 上是 libfoo.dynlib，在 win32 上是 foo.dll）。在大多数现代系统中，它会要求您或您的模块的用户安装开发包，因为建议始终为共享库提供 API/ABI 版本，因此 libfoo.so 结尾通常是仅由开发提供的符号链接包裹。

为避免这种情况，本机特征允许您指定 API/ABI 版本。它可以是完整版本，也可以只是其中的一部分。（尽量坚持 Major 版本，一些 BSD 代码不关心 Minor。）

看起来 Readline没有指定特定的 API/ABI 版本。（也许应该？）

因为它没有，它会寻找未版本化的共享库（plain .so）。

请参阅此 perl6-readline 问题。

在@drforr 有时间整理版本之前，我创建了一个临时分支，可以在 Ubuntu 18.04 和所有使用 libreadline 版本 7 的发行版上正常安装。

要安装模块：

$ zef install https://github.com/nxadm/perl6-readline.git

如果您想自己修补问题（1 行补丁），可以按照我对相关问题的评论中的说明进行操作。
