【问题描述】：

我试图理解错误已经好几个小时了，但我不明白。

我尝试将我的 ruby 版本从 2.5 升级到 2.7.4

我首先从brew更新rbenv然后安装2.7.4版本并使用rbenv rehash

但是现在每当我启动rails c 或rails s 时，都会出现以下错误：

我尝试从 brew 重新安装 rbenv 但没有成功，我花了几个小时试图理解这个错误的含义，但作为初学者我不明白。

我应该寻找什么？

编辑：它不是来自 bootsnap，因为如果我删除 bootsnap 也会遇到同样的问题

【问题讨论】：

您是否在现有项目中运行rails c？如果你开始一个新的 Rails 项目会发生什么？
是的，我从现有项目中运行它。我只是尝试创建一个新的 rails 项目，然后运行 rails c 并且它工作正常。
在（隐式）brew upgrade 运行期间，您现有 gem 的某些依赖项可能已更新。您可以尝试使用 bundle pristine 重新安装项目的所有 gem
它与bundle pristine 一起使用，如果你愿意，可以将其添加为答案，然后我可以验证你的答案:) 谢谢你的帮助

【解决方案1】：

在您安装其他软件时，在（隐式）brew upgrade 运行期间，您现有 gem 的某些依赖项可能已更新。

在安装使用库依赖项的 gem 时（例如在您的情况下为 libgdal），如果底层库以不兼容的方式发生更改，有时可能需要重新编译这些 gem。

因此，第一次尝试解决此问题以重新安装受影响的 gem。如果你使用 bundler，你可以通过运行重新安装项目的所有 gems

bundle pristine

这应该确保您的捆绑程序管理的 gem 都使用最新版本的库。请参阅the documentation of bundle pristine 了解此命令在后台执行的详细信息。
