我尝试使用该命令卸载datamapper gem uninstall dm-core.

但似乎还需要卸载一大堆依赖宝石.

C:\>gem uninstall dm-core

You have requested to uninstall the gem:
        dm-core-0.9.11
dm-migrations-0.9.11 depends on [dm-core (= 0.9.11)]
dm-cli-0.9.11 depends on [dm-core (= 0.9.11)]
dm-serializer-0.9.11 depends on [dm-core (= 0.9.11)]
dm-timestamps-0.9.11 depends on [dm-core (= 0.9.11)]

我有一台新的 m1 mac，但无法安装eventmachinegem，完整日志如下。

我尝试了这些解决方案：

\n
• 在 m1 上安装带 ssl 的 gem eventmachine 1.2.7
\n
• eventmachine 无法在 macOS \xc2\xb7 上使用 ruby​​ 3.0.0preview1 进行编译问题 #932 \xc2\xb7 eventmachine/eventmachine
\n

同样的错误。

一些信息：

   $ sw_vers\nProductName:    macOS\nProductVersion: 12.2\nBuildVersion:   21D49\n\n   $ bundle --version\nBundler version 2.1.4\n

和错误：

   $ gem install eventmachine -v \'1.2.7\'                                                    \n

em.cpp:706:13: error: use of undeclared identifier \'rb_thread_select\'; did you mean \'rb_thread_fd_select\'?\n        if ((ret = rb_thread_select(kqfd + 1, &fdreads, NULL, NULL, &tv)) < 1) {\n …

更新:

eventmachine gem已安装在我的gemfile中:

 eventmachine (1.0.0, 0.12.10)

请帮忙!尝试使用以下内容创建数据库:

Fitzs-MacBook-Pro:twilio_insanity Fitz$ rake db:create'

返回以下错误:
