Question

所以我遇到了以下问题：

Your Ruby version is 2.3.1, but your Gemfile specified 2.3.1

在我部署应用程序时说Heroku。只有当您与当前的ruby版本和Gemfile的ruby版本不匹配时才会出现此错误。

您可以看到任何代码here

这是构建输出：

导致此错误的原因是什么？

Answer 1

哇哇哇哇哇哇哇哇哇哇哇哇哇

发现问题：

我从.ruby-version读取了ruby版本，因为rbenv在执行rbenv local 2.3.1时会生成此文件。该文件在版本号后有一个中断。（修正了here）

我用这段代码来读它：

ruby_version_file = File.expand_path(".ruby-version", __dir__)
ruby File.read(ruby_version_file)

File.read(ruby_version_file)返回"2.3.1\n"时...但是在heroku构建日志中，这很难看到。

Answer 2

在Jenkins构建自动化中，我有完全相同的错误，但是在不同的上下文中。在我的情况下，解决方案是调用：

dplyr

调用现有代码行：rbenv rehash

您的Ruby版本是2.3.1，但您的Gemfile指定为2.3.1（相同版本）
