自制软件：忽略 bigdecimal-1.3.2，因为它的扩展未构建

Question

总是当我运行 brew update 出现 Ignoring bigdecimal-1.3.2 because its extensions are not built. Try: gem pristine bigdecimal --version 1.3.2 警告时：

> 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 修订版 77cae；最后一次提交 2018-10-19），Homebrew/homebrew-cask（git 修订版 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 也没有修复它。

gem environment 向我展示了 2 gem 条路径。可以吗？

Answer 1

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 "remove" 固定为 "uninstall"）
