升级后得到 ruby：找不到符号：__ZN6libdap5ErrorD1Ev

Question

我花了好几个小时试图理解这个错误，但我不明白。

我已经尝试将我的 ruby 版本从 2.5 升级到 2.7.4

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

但现在每当我启动 rails c 或 rails s 时，我都会遇到以下错误：

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，我会遇到同样的问题

Answer 1

您现有 gem 的某些依赖项可能已在（隐式）brew upgrade 运行期间更新，因为您安装了其他软件。

安装使用库依赖项的 gem 时（例如您的情况下的 libgdal），如果底层库有这些 gem 有时可能需要重新编译以不兼容的方式更改。

因此，通常首先尝试修复此问题以重新安装受影响的 gem。如果您使用捆绑器，您可以通过运行ning

重新安装项目的所有 gems

bundle pristine

这应该确保您的捆绑器管理的 gem 都使用最新版本的库。有关此命令的详细信息，请参阅 the documentation of bundle pristine。
