我在 $('body').height('auto')
中有此代码我在 javascript/packs/style.js 中使用 `require("packs/style") 需要它。但是当我刷新页面时，我在控制台中收到此错误。
application.js这是Uncaught Error: Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: /home/maryan/Desktop/workspace/collabfield/app/javascript/posts/style.js: Unexpected token, expected "," (20:0)

中的代码
style.js我正在 $(document).on('turbolinks:load', function() {
if ($(".single-post-card").length) {
// set a solid background color style
if (mode == 1) {
$(".single-post-card").each(function() {
$(this).addClass("solid-color-mode");
$(this).css('background-color', randomColor());
});
}
// set a border color style
else {
$(".single-post-card").each(function() {
$(this).addClass("border-color-mode");
$(this).css('border', '5px solid ' + randomColor());
});
}
}
$('#feed').on( 'mouseenter', '.single-post-list', function() {
$(this).css('border-color', randomColor());
});
$('#feed').on( 'mouseleave', '.single-post-list', function() {
$(this).css('border-color', 'rgba(0, 0 , 0, 0.05)');
});
});
var colorSet = randomColorSet();
var mode = Math.floor(Math.random() * 2);
// Randomly returns a color scheme
function randomColorSet() {
var colorSet1 = ['#45CCFF', '#49E83E', '#FFD432', '#E84B30', '#B243FF'];
var colorSet2 = ['#FF6138', '#FFFF9D', '#BEEB9F', '#79BD8F', '#79BD8F'];
var colorSet3 = ['#FCFFF5', '#D1DBBD', '#91AA9D', '#3E606F', '#193441'];
var colorSet4 = ['#004358', '#1F8A70', '#BEDB39', '#FFE11A', '#FD7400'];
var colorSet5 = ['#105B63', '#FFFAD5', '#FFD34E', '#DB9E36', '#BD4932'];
var colorSet6 = ['#04BFBF', '#CAFCD8', '#F7E967', '#A9CF54', '#588F27'];
var colorSet7 = ['#405952', '#9C9B7A', '#FFD393', '#FF974F', '#F54F29'];
var randomSet = [colorSet1, colorSet2, colorSet3, colorSet4, colorSet5, colorSet6, colorSet7];
return randomSet[Math.floor(Math.random() * randomSet.length )];
}
// Randomly returns a color from an array of colors
function randomColor() {
var color = colorSet[Math.floor(Math.random() * colorSet.length)];
return color;
}
我不知道是我的代码有问题还是有其他问题。
非常感谢任何帮助或想法...

这个 ./node_modules/babel-loader/lib/index.js) 模块构建错误肯定会随机出现在 rails 6 的 Webpacker 中。据我了解，rails 6 中的整个 webpacker 设置非常脆弱。为了解决这个问题，我做了一个干净的重新安装：
yarn remove @rails/webpacker
yarn remove webpack webpack-cli webpack-dev-server
rm -fr node_modules
rm -fr public/packs
bundle exec rails webpacker:install
# REMOVE any invalid babel preset from package.json added by "webpacker:install"
yarn add node-releases
bundle exec rails webpacker:compile
使用 style.js 将 application.js 添加到 require("packs/style")
#Success
