家酿：忽略的BigDecimal-1.3.2，因为它的扩展名不建

Question

我总是跑brew update的Ignoring bigdecimal-1.3.2 because its extensions are not built. Try: gem pristine bigdecimal --version 1.3.2警告显示出来：

> 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.

我使用的是自制v1.7.7（自制/自制核（GIT版本77cae;最后提交2018年10月19日），自制/自制-桶（GIT版本c95843;最后提交2018年10月19日））和rbenv V1 .1.1。

我已经做gem pristine bigdecimal --version 1.3.2和它说：

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

即使gem pristine --all不固定它。

该gem environment是显示我2条宝石路径。是罚款？

Answer 1

请确保你使用正确的gem。下面的固定对我来说：

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