在任何来源中都找不到 bcrypt-3.1.12

Could not find bcrypt-3.1.12 in any of the sources

我在我的项目中安装了 gem 'devise'。这样做之后,我尝试迁移数据库;然而,由于 "Could not find bcrypt-3.1.12 in any of the sources",这似乎停止了。它告诉我 运行 bundle install 再次安装,这似乎不起作用。我必须提到该项目 运行 正在 docker。

我尝试卸载 gem 并重新安装,并删除了 gemfile.lock 文件。这些也失败了。

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

  # Call 'byebug' anywhere in the code to stop execution and get a debugger console

end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem

问题已通过重建 docker 服务得到解决

docker-compose --build app
