CircleCI 缓存键不匹配

Question

当我运行构建我的构建时，它在处理捆绑程序缓存时显示此输出：

正在恢复缓存：

No cache is found for key: gems-E2sY+gLiTCg0YwHjev8ZrCqAW_U9vUHKPA_FZnRiAPc=-circleci-project-setup
No cache is found for key: gems-E2sY+gLiTCg0YwHjev8ZrCqAW_U9vUHKPA_FZnRiAPc=

保存缓存

Uploading cache archive...
Stored Cache to gems-wV_lhNyGV+evee5LBWbzjy7uuCEgZRgX8PlgbJreAv4=-circleci-project-setup
  * /home/circleci/project/vendor/bundle

但它用于保存的密钥与用于获取的密钥不匹配。因此构建的下一个运行将有另一个缓存未命中

我该如何解决这个问题才能正确存储缓存

Answer 1

我想我找到了问题。

我在构建项目时从未推送过 Gemfile.lock 文件。我认为 gemfile.lock 文件被散列以生成密钥，因为存储库包含一个散列不匹配的旧 gemfile。在运行 bundler 之后，锁文件发生变化，因此它获得了一个新的散列（已经存在）。因为我从来没有在本地运行捆绑器，它从来没有更新我的本地 gemfile.lock 所以它从来没有被推送到 repo。
