ruby - Gem::Specification:Class 的未定义方法 `stubs_for' (NoMethodError)

问题描述

这些天来，我尝试使用最小错误主题来构建我的 github 博客。

在最后的快速指南中有说

bundle exec jekyll serve

结果

`find_name': undefined method `stubs_for' for Gem::Specification:Class (NoMethodError)

具体的

C:\Users\all7j\Documents\project\elephantoid.github.io>bundle exec jekyll serve

Did you mean?  stubs

我找不到 stubs_for 的内容。

而且我不知道是什么问题...我只是按照快速指南的步骤进行操作。

我在 Windows 上安装了 gem、ruby、bundler。并 fork GitHub，更新 _config.yml 等等……

解决方案

我有一个类似的案例是通过以下方式带给我的passenger.log：

[ 2020-12-07 20:13:44.4960 18738/7f0b659e8700 agents/HelperAgent/RequestHandler.h:2306 ]: [Client 19] Cannot checkout session because a spawning error occurred. The identifier of the error is e907d6aa. Please see earlier logs for details about the error.

就我而言，这是一个 ruby​​gems 版本更改。根据您的应用程序和预期版本，您希望在下面适当地替换它：

gem install -v 2.7.7 rubygems-update && gem update --system 2.7.7

您可能还想在重新安装之前卸载以前的 ruby​​gems-update：

gem uninstall rubygems-update

Select gem to uninstall:
 1. rubygems-update-2.4.8
 2. rubygems-update-2.6.13
 3. All versions
> 3
Successfully uninstalled rubygems-update-2.4.8
Remove executables:
    update_rubygems

in addition to the gem? [Yn]  y
Removing update_rubygems
Successfully uninstalled rubygems-update-2.6.13

并清理相应的文件夹：

rm -f /usr/local/bin/update_rubygems
