在 ruby-2.2.2 上为 travis-ci 加密文件失败 "private method `load' called for Psych:Module"

Question

我在为 Travis CI 加密我的 database.yml 时遇到问题。基于他们的 documentation, it appears you encrypt files with the travis encrypt-file command。我运行正在 Ruby-2.2.2 上，它给了我一些非常神秘的错误消息。

travis encrypt-file config/database.yml --add

我得到这个错误：

private method `load' called for Psych:Module
for a full error report, run travis report

这是我运行 travis report:

Answer 1

解决方案是卸载 Psych 版本 2.0.13，我的机器上只有 2.0.5。我同时拥有 2.0.5 和 2.0.13，它们似乎相互冲突。我在 this forum post.

上找到了信息

Answer 2

gem update --system

在 Ubuntu 14.04 + RVM + Ruby 2.1.1p76 上为我解决了这个问题，如在：https://github.com/bbatsov/rubocop/issues/1510#issuecomment-102645627
