ZeroMQ gem 无法在 macOS Catalina 上安装

Question

我正在尝试在 macOS 10.15.3 上安装和使用 zeroMQ gem。 但是我收到一个构建错误，请参阅最后一个代码片段。 我像这样使用 bundle 安装： bundle install --path vendor/bundle和我的 Gemfile 像这样：

source "https://rubygems.org"

git_source(:github) {|repo_name| "https://github.com/#{repo_name}" }

gem "sinatra"
gem "pg"
gem "zmq"

但是 zeroMQ 的 gem 安装失败。 我觉得奇怪的是，原始 C zeroMQ、cppzmq 和我都可以使用 PIP 为 python 安装 zeroMQ，没有任何问题。 zeroMQ 是使用 Homebrew 安装的。

任何见解都适用。

An error occurred while installing zmq (2.1.4), and Bundler cannot continue.
Make sure that `gem install zmq -v '2.1.4' --source 'https://rubygems.org/'` succeeds before bundling.

Answer 1

zmq gem 很旧： https : //rubygems.org/gems/zmq - 上次更新是在 2010 年进行的。有许多已知的兼容性问题，例如参见： https : //github.com/zeromq/rbzmq/issues /32 。

我建议您改用 gem rbczmq ： https : //github.com/methodmissing/rbczmq

Answer 2

让 ffi-rzmq 运行没有问题。

https://github.com/chuckremes/ffi-rzmq

gem install ffi-rzmq
