bundle exec rake db：migrate说运行`bundle install`

Question

bundle install

这完全没问题。但是当我做的时候

bundle exec rake db:migrate

它说

Could not find byebug-6.0.2 in any of the sources
Run `bundle install` to install missing gems.

Answer 1

从评论中，我看到你使用了两种不同类型的命令，一种是sudo，另一种是没有。

问题是：sudo是另一个用户（root用户），因此sudo安装的内容可能不适用于其他用户，反之亦然。

我能想到的解决方案是使用所有sudo命令，因为您当前的用户似乎无法访问PG。

sudo bundle install
sudo bundle exec rake db:migrate

Answer 2

I just troubleshat this same problem. I finally tried removing byebug and was offered a choice of byebug_6.0.2 or byebug_8.1.0. Removing the earlier version didn’t do it so I removed the other as well. I then reinstalled using

gem install byebug

That gave me another failed migrate, this time blaming debug_inspector. I ran

gem install debug_inspector

After that I was able to run rake db:migrate as expected.
