我应该用机架覆盖机架吗？
Should I overwrite rack with rackup?
问：
我正在尝试更新到最新版本的 Rails 并收到以下错误：
➜ ~ gem update rails
Updating installed gems
Updating rails
rackup's executable "rackup" conflicts with rack
Overwrite the executable? [yN]
ERROR: Error installing rails:
"rackup" from rackup conflicts with installed executable from rack

我在 Ubuntu 23.10 安装时遇到了同样的问题。在阅读了关于您的问题的评论后，我中断了安装并安装了 gem。打开新 shell 并重新运行已完成，没有问题。railsrackupgem install rails
已安装的 gemrackup
$ gem install rackup
rackup's executable "rackup" conflicts with rack
Overwrite the executable? [yN] y
Successfully installed rackup-2.1.0

同时更新了 RubyGems
NOTE:
A new release of RubyGems is available: 3.4.14 → 3.4.22!
Run `gem update --system 3.4.22` to update your installation.
$ gem update --system 3.4.22

之后 7.1.2 安装没有错误：rails
$ gem install rails
. . .
$ rails -v
Rails 7.1.2
