如何在 M1 Mac 上安装 ruby​​-odbc gem

Question

我正在尝试让 Rails 项目在 M1 mac 上运行。我必须使用 ruby​​ 2.6.2 和rails 5.2.3

我正在使用 rbenv 1.1.2 和 homebrew 3.0

当我运行时bundle install，我收到此错误

An error occurred while installing ruby-odbc (0.99999), and Bundler cannot continue.
  Make sure that `gem install ruby-odbc -v '0.99999'` succeeds before bundling.

然后我跑gem install ruby-odbc -v '0.99999'

这会导致另一个错误

ERROR:  Error installing ruby-odbc:
ERROR: Failed to build gem native extension.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

当我 stackoverflow 这个错误时，我收到这篇文章，告诉我要这样做brew install unixodbc，所以我这样做并再次尝试bundle install，这给了我同样的错误。

所有与未安装 sql.h 文件相关的 stackoverflow 帖子都不能解决我的问题。

我如何安装这个 Gem？

Answer 1

感谢同事的帮助，我解决了这个问题。您需要安装 gem，同时将其指向 unixodbc 目录

这是为我安装的生产线

gem install ruby-odbc -- --with-odbc-dir=/opt/homebrew/Cellar/unixodbc/2.3.9

要查找您的 unixodbc 路径，请运行brew info unixodbc

这将为您提供 unixodbc 的路径和版本号。然后将路径和版本号放在适当的位置 gem install ruby-odbc -- --with-odbc-dir=put your path and version number of unixodbc here
