ruby-on-rails - Ruby 导入项目要求 Puma

Question

我刚进入一个新项目，我必须学习 Ruby。我做了一些教程，一切都很顺利。我什至能够为我的新生应用程序创建一个网络服务器。
但是，当我导入项目(使用 GIT)并尝试运行它时，我发现自己无法启动 WEBrick 服务器(使用 rails server)。

这是错误消息:

C:\Projects\BookRosa\bin>rails 服务器
在任何来源中都找不到 puma-2.9.2
运行 bundle install 以安装缺少的 gem。

当我运行 bundle install 时:

C:\Projects\BookRosa\bin>bundle install

An error occurred while installing puma (2.9.2), and Bundler cannot continue.
Make sure that `gem install puma -v '2.9.2'` succeeds before bundling.

我已经尝试了 http 和 https 源，安装 devkit，安装 openssl，错误不会消失。我不一定要用puma，但我也脱不下来。我刚创建的应用程序运行良好，所以我不知道问题出在哪里，因为我是 Ruby 的新手

运行 gem install puma -v '2.9.2' 返回以下内容:

checking for SSL_CTX_new() in -lssl... 
no checking for SSL_CTX_new() in -lssleay32...

我刚遇到同样的问题。这issue帮我弄明白了。

我首先尝试了 brew install openssl && brew link --force openssl 但我已经安装了它。

我的解决方法是运行:

gem install puma -v '2.9.2' -- --with-opt-dir=/usr/local/opt/openssl

希望这对你也有用。
