在生产中找不到文件“ twitter / bootstrap”

将rails应用程序部署到heroku.com时看到类似这样的内容

Precompiling assets failed, enabling runtime asset compilation
...
could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port xxxx?

只需将其添加到config / application.rb

config.assets.initialize_on_precompile = false

只需将其放入您的gemfile

gem "twitter-bootstrap-rails", "~> 2.0rc0"

BootStrap 2.0中存在无效的CSS，这会导致SCSS编译失败

您可以通过查看输出来验证这一点

git push heroku master

您应该看到一些错误，例如：

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       rake aborted!
       Invalid CSS after "...er-radius:0 \0/": expected expression (e.g. 1px, bold), was ";}"
       (in /tmp/build_1k8ugei34dpcw/app/assets/stylesheets/application.css)

       Tasks: TOP => assets:precompile:primary
       (See full trace by running task with --trace)
       Precompiling assets failed, enabling runtime asset compilation

确保在config / environments / production.rb中，您有...

config.serve_static_assets = true

猴子村村 2020.03.24

在config/environments/production.rb添加此行：

config.assets.precompile = [/^[-_a-zA-Z0-9]*\..*/]

我的猜测是它不会添加您的所有资产。

您在使用宝石吗？确保您的宝石不属于资产组，并且可以在生产中访问。

从GemFile

# Gems used only for assets and not in production environments by default.

因此，只需将宝石移到任何组之外，就可以了。
