Bootsnap::LoadPathCache::Store::NestedTransactionError：

Question

我用ReactNative和RubyOnRails开发了一个应用程序。我已经在下面描述的错误中挣扎了十天。

我用以下软件包初始化了我的Mac：

Software/Versions
  Ruby '2.5.1'
  Rails 5.2.1
  bootsnap (1.3.1)

/config/boot.rb包含：

ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../Gemfile', __dir__)
require 'bundler/setup' 
# Set up gems listed in the Gemfile.
require 'bootsnap/setup' 
# Speed up boot time by caching expensive operations.

终端显示以下错误信息：

#<Bootsnap::LoadPathCache::Store::NestedTransactionError:

尝试删除tmp/cache目录。这对我很有帮助(这个问题发生在gem更新之后)。
