ruby - Homebrew 软件:忽略bigdecimal-1.3.2，因为未构建其扩展名

总是在我运行brew update时出现Ignoring bigdecimal-1.3.2 because its extensions are not built. Try: gem pristine bigdecimal --version 1.3.2警告:

> brew update
Ignoring bigdecimal-1.3.2 because its extensions are not built.  Try: gem pristine bigdecimal --version 1.3.2
Ignoring bigdecimal-1.3.2 because its extensions are not built.  Try: gem pristine bigdecimal --version 1.3.2
Already up-to-date.

我正在使用Homebrew v1.7.7(Homebrew/homebrew-core(git版本77cae;最后一次提交2018-10-19)，Homebrew/homebrew-cask(git版本c95843;最后一次提交2018-10-19))和rbenv v1 .1.1。
我已经做了gem pristine bigdecimal --version 1.3.2，它说:

> gem pristine bigdecimal --version 1.3.2
ERROR:  While executing gem ... (Gem::Exception)
    Failed to find gems ["bigdecimal"] = 1.3.2

甚至gem pristine --all也无法修复它。gem environment向我显示2条 gem 路径。这样好吗

最佳答案

确保您使用的是正确的gem。以下为我修复了它:

$ which ruby
/usr/local/bin/ruby
$ /usr/bin/gem uninstall bigdecimal --all --force

(编辑:将“删除”修复为“卸载”)
