Question

我完全不了解Ruby，我只是试图用它来加密我的.travis.yml的参数。每当我运行travis pubkey -r user/project时，我都会收到错误

undefined method `try' for #<Faraday::Env:0x289a748>
for a full error report, run travis report

完整的报告是（我更改了一些私人数据）：

有人能告诉我我做错了吗？

Answer 1

很可能缺少gem faraday。尝试通过在gemfile中添加以下内容来安装它：

gem 'faraday'

其次是

bundle install

<强>替代地：

gem install faraday

Answer 2

我在github上发现了一个问题，它解释了发生了什么：https://github.com/travis-ci/travis.rb/issues/265

TL; DR：降级gh：

gem uninstall gh
gem install gh -v 0.13.2
