在我的带Catalina的iMac(10.15.6(上，我安装了augeas brew包，然后安装了perl模块"配置：：Augas"；没有问题。在大苏尔，我没有取得同样的成功。在安装冲泡包装之后；cpanm Config:：Augas"；，我在构建日志中得到以下输出：

这两台机器都在运行perlbrew(尽管perl的版本不同(。我不认为perl的版本是问题所在，更可能是Big Sur做了一些perl模块不喜欢的更改。有什么想法吗？
问题是libtool中的一个错误，它导致动态库使用平面名称空间编译。这再次导致共享库libSystem.B.dylib和libfa.1.dylib中具有相同名称的两个符号之间的冲突。两个库都声明了一个名为hash_create()的符号，但是Perl模块需要将该符号解析为libfa.1.dylib，但libSystem.B.dylib总是在libfa.1.dylib之前加载，因此使用了错误版本的hash_create()。
该问题以前曾遇到过，请参阅此问题。可以在这里找到进一步的解释。
由于对libtool中错误的修复尚未作为libtool的新版本发布，因此问题并不是简单地通过升级xcode命令行工具来解决的。相反，您可以尝试下载libaugeas源代码并从以下源代码进行编译：
$ brew uninstall augeas
$ wget http://download.augeas.net/augeas-1.12.0.tar.gz
$ cd augeas-1.12.0
$ MACOSX_DEPLOYMENT_TARGET=10.15 ./configure
$ make
$ make install
注意：通过在上面的命令中指定MACOSX_DEPLOYMENT_TARGET=10.15，我们可以解决错误，因此不必修补configure。
Perl模块现在应该可以安装了。
另一种解决方法是：可以对libfa.1.dylib使用动态链接(而不是动态加载(。为了实现这一点，我将模块重写为ExtUtils:MakeMaker，而不是module:：Build。接下来要使用动态链接进行安装，您可以执行以下操作：
git clone https://github.com/hakonhagland/Config-Augeas-MM.git
cd https://github.com/hakonhagland/Config-Augeas-MM.git
perl Makefile.PL
make perl
make -f Makefile.aperl inst_perl MAP_TARGET=perl
注意：最后一个命令会覆盖现有的perl二进制文件，所以要小心，请参阅此链接以获取更多信息。
现在，该模块可以成功测试和安装：
