任何捆绑命令都会清除 Gemfile.lock 文件内容

Question

目前的Gemfile.lock是这样的：

运行 bundle 或 bundle install 只是删除整个 Gemfile.lock 内容并保留如下：

GEM
  remote: https://rubygems.org/
  remote: https://rails-assets.org/
  specs:

DEPENDENCIES

捆绑命令的输出：

The Gemfile specifies no dependencies
Resolving dependencies...
Your bundle is complete!
It was installed into ./vendor/bundle

为什么会这样？

Answer 1

Bundler 版本（1.6.2 很旧）及其配置有问题，只需删除配置并更新 bundler：

cd app_dir
rm -v .bundle/config
gem update bundler
bundle install

在发出最后一个命令之前确保 Gemfile 语法正确。
