无法检测到 rake 任务确保您可以对您的应用程序运行 `$ bundle exec rake -P`

Question

我一直在尝试运行git push heroku master并且我继续收到以下错误：

我运行了上面建议的所有内容并继续收到错误消息。 然后我按照本指南进行操作： 无法检测到 rake 任务

最新的一个，我开始收到这个错误：

Answer 1

这不会解释您遇到的第二个错误，但解决第一个错误中捆绑程序问题的一个可能解决方法是从Gemfile.lock文件中删除“ Gemfile.lock WITH”行。 它们应该是文件的最后两行，并且（根据您的错误）应该类似于：

BUNDLED WITH
  2.0.1

每次运行bundle install时，这些行将重新出现在Gemfile.lock文件中，因此您需要在运行该命令后推送到 heroku 时删除它们。 我还没有找到更永久的解决方案，但这对我解决了这个错误很有帮助。

Answer 2

看起来您在本地有捆绑程序版本 2.0.1，但 heroku 正在运行 2.0.2。 你可以尝试在你的机器上更新 bundler： gem install bundler然后在你的项目中重新运行bundle install 。

如果您无法更新捆绑程序，您也可能会遇到此问题： https : //github.com/rvm/rvm/issues/3923 。 特别是：

...you are using rvm-1.29.1 or later it is likely caused by a pre-1.1 OpenSSL version that is installed or symlinked to /usr/local.

You can check which formula /usr/local/bin/openssl is symlinked to and to a brew unlink <fomula> and then do a rvm reinstall of the broken ruby version.
