[英]Ruby on Rails 6 Bootstrap undefined variable error on server restart
我在 rails 6 中遇到問題,當我重新啟動服務器時,出現錯誤:未定義變量。 如果我注釋掉文件中的任何 scss 變量,請刷新頁面,取消對變量的注釋並再次刷新一切正常,我可以再次在我的 CSS 文件中使用變量。 我不太確定為什么會發生這種情況,任何人都可以提供任何幫助,我們將不勝感激。
這是我的 application.scss 文件:
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, or any plugin's
* vendor/assets/stylesheets directory can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any other CSS/SCSS
* files in this directory. Styles in this file should be added after the last require_* statement.
* It is generally better to create a new file per style scope.
*
*= require_self

@import "custom_variables";
@import 'bootstrap/scss/bootstrap';
@import "@fortawesome/fontawesome-free/css/all.css";
@import 'layouts';
@import 'themes';
@import 'typography';
@import 'states';
以下是我在其中使用變量的文件:
.dropdown-menu {
display: block;
visibility: hidden;
opacity: 0;
transition: all .3s;
}
@media only screen and (min-width: map_get($grid-breakpoints,"lg")) {
.dropdown:hover>.dropdown-menu {
visibility: visible;
opacity: 1;
}
}
@media only screen and (max-width: map_get($grid-breakpoints,"lg")) {
.dropdown-menu {
display: none;
}
}
.footer a:hover {
text-decoration: none;
}
.bg-dark-red {
background-color: $banner-color;
}
.navbar, .footer {
background-color: $navbar-bg-color;
a {
color: $navbar-color;
}
a:hover {
color: $navbar-hover-color;
}
.active {
color: $navbar-active-color;
}
}
.dropdown-menu {
background-color: $navbar-bg-color;
a {
color: $navbar-color;
}
a:hover {
color: $navbar-hover-color;
background-color: inherit;
}
.dropdown-divider {
border-top-color: $dropdown-border-color;
}
}
section.map {
background-color: $map-bg-color;
}
.btn-primary {
@include button-variant($primary-btn-color, darken($primary-btn-color, 7.5%), darken($primary-btn-color, 10%), lighten($primary-btn-color,5%), lighten($primary-btn-color, 10%), darken($primary-btn-color,30%));
}
關於我可以做些什么來阻止這種情況發生的任何建議?
編輯:我忘記包含導入變量的文件,這里是:
$white: #fff;
$black: #000;
$primary-color: #FF0103;
$complementary-color: complement($primary-color);
$navbar-color: rgba($white, .55);
$navbar-bg-color: #343A40;
$navbar-hover-color: rgba($white, .75);
$dropdown-border-color: rgba($black, .15);
$navbar-active-color: $white;
$banner-color: $primary-color;
$primary-btn-color: #198754;
$map-bg-color: #E1E1E1;
我也面臨着同樣的問題。 這太令人沮喪了。 首先刪除 application.scss 文件中的所有注釋,尤其是具有*= require_self
。 任何使用引導變量的文件都應該有@import 'bootstrap/scss/bootstrap';
在頂部。 以下將不起作用:
應用程序.scss:
@import 'bootstrap/scss/bootstrap';
@import 'custom.scss"
自定義.css:
body {
background-color: $gray-200;
}
而是移動@import 'bootstrap/scss/bootstrap';
從application.scss 到custome.scss,然后它將如下所示工作:
自定義.scss:
@import 'bootstrap/scss/bootstrap';
body {
background-color: $gray-200;
}
