捆绑软件可以告诉我Gemfile中的哪些宝石具有更新的版本（例如，试运行的捆绑软件更新） [英] Can bundler show me which gems in Gemfile have newer versions (eg. dry-run of bundle update)

问题描述

有没有办法在假装模式下运行捆绑更新

Is there a way to run bundle update in pretend mode, similar to the -p (pretend) flag for Rails generators or cap's -n (dry-run) flag?

我想像这样的东西：

$> bundle update -p
Fetching source index for http://rubygems.org/
The following gems have updated versions:
...
list of gems
...

推荐答案

Bundler 1.1引入了新的过时功能，这正是我想要的。 Pat Shaughnessy具有出色的撰写有关新功能的信息。用他的话说，捆绑包已过期：

Bundler 1.1 introduced a new 'outdated' feature, which is exactly what I was looking for. Pat Shaughnessy has a great write-up on the new features. In his words, bundle outdated:

显示将下载并安装的宝石，但实际上没有
这样做。这使我可以自由地检查列表并仅更新我想要的宝石
。

displays the gems it would download and install, but without actually doing it. This gives me the freedom to inspect the list and update just the gems I would like to.

快速查看需要更新的宝石，而无需实际修改源宝石和本地宝石。谢谢邦德勒！

This should make it a snap to see what gems are due for an update without actually modifying your source and local gems. Thanks Bundler!
