过时的 GEM 文件和新的 ruby ..从哪里开始？答案

【问题标题】：Way out of date GEM file and new to ruby..where to begin?过时的 GEM 文件和新的 ruby ..从哪里开始？

【问题描述】：

这是 2015 年的一个项目......所以没有任何更新或新的......只是倾倒在我的盘子里。

运行捆绑安装后所以我想知道我应该从哪里开始解决这个问题。

来自 PHP/Python 背景....不喜欢这个 ruby ;)

【解决方案1】：

这个 Rails 版本记住了最后的猛犸象，所以你期待什么？ :)

第一件事：

仔细检查您是否尝试在最前沿的 Ruby (3.x) 上构建此项目。即使是最新的 2.x 也可能是旧版 Rails 的问题。谷歌“Rails & Ruby 兼容性”来检查这个化石推荐使用哪个 Ruby 版本，不要试图走得太远。使用一些 Ruby 版本管理器在版本之间轻松切换（我的选择是 asdf，但更常见的 rbenv 或 rvm 也可以）。
删除Gemfile.lock（将其复制到某处以防万一）。 Bundler 将依赖项锁定在那里以最小化依赖项更改的表面。在正常的开发周期中这是一件非常好的事情，但对于像你必须处理的“考古发掘”来说，这可能是一个问题。删除锁定文件后，捆绑程序将从头开始重新评估依赖关系图，因此您现在看到的大多数冲突都应该得到解决。大概：）

做好准备，即使在此之后，您可能会遇到捆绑程序无法自行解决的冲突（由于某些旧版本的依赖项不再可用等）。
