ruby-on-rails - bson_ext gem 在 macOS 上安装失败

Question

我坚持使用 1.5.1 版本安装 bson_ext gem。我已经尝试了几乎所有我在网上找到的东西，但没有任何帮助。
我尝试重新安装 ruby​​、rvm 等。
我在用:

RVM

MacOs Catalina 10.15.6

ruby 2.6.5

在捆绑安装后，我得到了这样的日志:

Fetching bson_ext 1.5.1

Gem files will remain installed in /Users/lukasz/.rvm/gems/ruby-2.6.5/gems/bson_ext-1.5.1 for inspection.
Results logged to /Users/lukasz/.rvm/gems/ruby-2.6.5/extensions/x86_64-darwin-19/2.6.0/bson_ext-1.5.1/gem_make.out

An error occurred while installing bson_ext (1.5.1), and Bundler cannot continue.
Make sure that `gem install bson_ext -v '1.5.1' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  bson_ext

任何人都知道我还能尝试什么？
另外我可以说 bson_ext 与其他版本如 1.9.1 安装成功。但是在这个项目中我必须使用 1.5.1。

Answer 1

这在 MacOS 11.2 上对我有用。gem install bson_ext -v '1.5.1' --source 'https://rubygems.org/' -- --with-cflags="-Wno-error=implicit-function-declaration"
