通过 rails-asset.org 安装 Fontawesome 并按照默认说明操作后,字体无法正确加载,我只看到方框,这表明生成用于加载字体的 URL 不正确。
gem 'font-awesome-rails'
2. 在您的scss文件中添加@import "font-awesome";
3. 完成!gem 'rails-assets-fontawesome'
,否则请忽略下面的所有内容!app/assets/stylesheets/font-awesome.scss
的新文件,其中包含以下内容:
fa-font-path: "fontawesome/fonts";
@import "fontawesome";
在 application.scss
中加入:
*= font-awesome
这样做应该可以解决问题,图标会开始显示。
备注:
如果您选择将 font-awesome.scss
移动到 app/assets/stylesheets/somedir/font-awesome.scss
下的某个目录中,则需要修复 fa-font-path
变量以具有正确的相对路径,如下所示:
fa-font-path: "../fontawesome/fonts";
注意路径和名称!
您创建的文件不能被称为 fontawesome.scss
,因为这是打包的 gem 使用的名称。
如果您拥有最新版本的 gem rails-assets-fontawesome (4.7.0)
,则导入和 fa-font-path 将使用 fontawesome
而不是旧版本的 font-awesome
。不确定此行为追溯到哪个版本。
config/initializers/assets.rb
文件来解决了这个问题:Rails.application.config.assets.paths << Rails.root.join('node_modules')
# font-awesome fonts
Rails.application.config.assets.precompile << %r{font-awesome/fonts/[\w-]+\.(?:eot|svg|ttf|woff2?)$}
并且,正如其他答案中提到的那样:
。application.scss
$fa-font-path: "fontawesome/fonts";
@import "fontawesome";
rake assets:precompile
,你应该可以看到字体文件在public/assets/font-awesome/fonts
中。5.5.0
,它应该是这个样子:$fa-font-path: 'fontawesome/web-fonts-with-css/webfonts';
@import "fontawesome";
// Copy-paste of these files:
// @import "fontawesome/solid";
// @import "fontawesome/regular";
// But url() replaced with font-url()
@font-face {
font-family: 'Font Awesome 5 Free';
font-style: normal;
font-weight: 400;
src: font-url('#{$fa-font-path}/fa-regular-400.eot');
src: font-url('#{$fa-font-path}/fa-regular-400.eot?#iefix') format('embedded-opentype'),
font-url('#{$fa-font-path}/fa-regular-400.woff2') format('woff2'),
font-url('#{$fa-font-path}/fa-regular-400.woff') format('woff'),
font-url('#{$fa-font-path}/fa-regular-400.ttf') format('truetype'),
font-url('#{$fa-font-path}/fa-regular-400.svg#fontawesome') format('svg');
}
.far {
font-family: 'Font Awesome 5 Free';
font-weight: 400;
}
@font-face {
font-family: 'Font Awesome 5 Free';
font-style: normal;
font-weight: 900;
src: font-url('#{$fa-font-path}/fa-solid-900.eot');
src: font-url('#{$fa-font-path}/fa-solid-900.eot?#iefix') format('embedded-opentype'),
font-url('#{$fa-font-path}/fa-solid-900.woff2') format('woff2'),
font-url('#{$fa-font-path}/fa-solid-900.woff') format('woff'),
font-url('#{$fa-font-path}/fa-solid-900.ttf') format('truetype'),
font-url('#{$fa-font-path}/fa-solid-900.svg#fontawesome') format('svg');
}
.fa,
.fas {
font-family: 'Font Awesome 5 Free';
font-weight: 900;
}
如果使用 fontawesome 4.*...
将字体从 fontawesome/fonts 复制到 Rails 的公共文件夹 public/fonts 中。
经过大约一天半的学习有关资产管道、缓存和其他有趣的主题,我终于找到了解决方法...
@import "font-awesome";
)# config/initializers/assets.rb
# Adde node_modules/ to the asset pipeline
Rails.application.config.assets.paths << Rails.root.join('vendor', 'assets', 'node_modules')
# Pre-compile any font files located in the asset pipeline
# This tells Rails to precompile the font files, fingerprint them, and place them in /public/assets/ (in the same subdir where they live in the pipeline)
# e.g.
# node_modules/@fortawesome/fontawesome-pro/webfonts/fa-solid-900.ttf (pipeline path)
# public/assets/@fortawesome/fontawesome-pro/webfonts/fa-solid-900-229b67ef16372975f562838a5c9f9bd2d9d9905ccc9c77f34c45f3d1f18f016f.ttf (pre-compiled asset path)
Rails.application.config.assets.precompile << /\.(?:svg|eot|woff|woff2|ttf)$/
# application.scss
@import "@fortawesome/fontawesome-pro/scss/fontawesome.scss";
// Don't use provided font imports b/c we need to use font-url to get asset paths with fingerprints!
// $fa-font-path: "../webfonts"; // Don't use this
// @import "@fortawesome/fontawesome-pro/scss/regular.scss"; // Don't use this
@import "fonts"; // Use this instead so that we can use font-url
# fonts.scss
/* Font Awesome 6 */
@font-face {
font-family: 'Font Awesome 6 Pro';
font-style: normal;
font-weight: 900;
src: font-url("@fortawesome/fontawesome-pro/webfonts/fa-solid-900.woff2") format("woff2"),
font-url("@fortawesome/fontawesome-pro/webfonts/fa-solid-900.ttf") format("truetype"); }
@font-face {
font-family: 'Font Awesome 6 Pro';
font-style: normal;
font-weight: 400;
src: font-url("@fortawesome/fontawesome-pro/webfonts/fa-regular-400.woff2") format("woff2"),
font-url("@fortawesome/fontawesome-pro/webfonts/fa-regular-400.ttf") format("truetype"); }
@font-face {
font-family: 'Font Awesome 6 Brands';
font-style: normal;
font-weight: normal;
src: font-url("@fortawesome/fontawesome-pro/webfonts/fa-brands-400.woff2") format("woff2"),
font-url("@fortawesome/fontawesome-pro/webfonts/fa-brands-400.ttf") format("truetype"); }
还有,其中最困难的事情之一就是意识到我的生产环境与我的开发环境不一致,所以我只能在部署后才意识到这个问题 :( 下面是如何避免这种情况...
# config/environments/development.rb
# Don't use pipeline if asset path fails
# config.assets.compile defaults to true in dev...so if the pre-compiled asset doesn't exist in public/assets/..., it will just pull from the pipeline and you won't know that you have an issue until you deploy!
config.assets.compile = false # This will raise an exception if the pre-compiled asset not found!
config.assets.debug = false # Pre-compile assets into single file
config.assets.digest = true # Use fingerprinting
现在,当然,这意味着您需要在开发中预编译资产,因此您需要从项目的根目录运行bundle exec rake assets:precompile
。这将预编译您的资产并将它们放置在 /public/assets/ 中。
如果您遇到缓存问题,即预编译器实际上没有重新编译资源,您可以通过运行rm -r tmp/cache/assets
来删除 Sprockets 缓存。
一旦您成功地将资产更改迁移到生产环境中,我建议将 development.rb 恢复为高效开发的默认设置。此外,您可能希望bundle exec rake assets:clobber
来删除预编译的资产。
以下是我事后发现的其他有用信息... https://guides.rubyonrails.org/asset_pipeline.html#in-development
希望这能帮助某人节省几个小时的“兔子洞” :)
无法在上面进行评论,但它不应该是:
$fa-font-path: "fontawesome/fonts";
您可以在宝石的建议导入之上正确地编写:
@import "fontawesome";
@font-face { src: url('#{$fa-font-path}/fontawesome-webfont.eot..'); ... }
。将url(..)更改为font-url(..)。 - Max Ivak
