Jquery不工作在角度6错误:ENOENT:没有这样的文件或目录,打开'... \node_modules\jquery\dist\jquery.min.js'

Question

我正在将Angular 5项目迁移到Angular 6.

在开始申请时

npm start

得到以下错误

 ** Angular Live Development Server is listening on localhost: 9000, 
open your browser on http://localhost:9000/ **
91% additional asset processing scripts-webpack-plugin× ?wdm?: 
Error: ENOENT: no such file or directory,open'\trunk\node_modules\jquery\dist\jquery.min.js'

我试过了

npm install jquery --save
npm install @types/jquery --save

什么都行不通

我检查了我的节点模块文件夹,我可以看到jquery文件

粘贴下面的package.json和angular.json

的package.json

请帮我解决这个问题.

Answer 1

有远见的团队再一次让事情变得更难而不是真正的原因=(

我遇到了这个问题,谷歌搜索后无果而终,我想知道他们是否以某种方式更改了相对路径以及重命名angular-cli.json.

在文件中稍微向上我发现了这一行:

是的,只需改变:

"../node_modules/jquery/dist/jquery.js",
"../node_modules/tether/dist/js/tether.js",
"../node_modules/bootstrap/dist/js/bootstrap.js"

至

"./node_modules/jquery/dist/jquery.js",
"./node_modules/tether/dist/js/tether.js",
"./node_modules/bootstrap/dist/js/bootstrap.js"

Answer 2

在 Angular 6 中你不需要写：

"../node_modules/jquery/dist/jquery.js",
"../node_modules/tether/dist/js/tether.js",
"../node_modules/bootstrap/dist/js/bootstrap.js"

你可以./在顶部用like写这也可以，但最简单的方法是在angular.json文件中：

"node_modules/jquery/dist/jquery.js",
"node_modules/tether/dist/js/tether.js",
"node_modules/bootstrap/dist/js/bootstrap.js"

在我看来它更好更清晰

Answer 3

我遇到过同样的问题。除非“npm install”命令中包含“--save”，否则安装似乎不会更新 package.json 文件。

换句话说，软件包应该安装

npm install --save bootstrap
npm install --save jquery
npm install --save popper.js

Answer 4

对于 Angular 6，路径如下：

来自：

"../node_modules/jquery/dist/jquery.js",
"../node_modules/tether/dist/js/tether.js",
"../node_modules/bootstrap/dist/js/bootstrap.js"

到

"./node_modules/jquery/dist/jquery.js",
"./node_modules/tether/dist/js/tether.js",
"./node_modules/bootstrap/dist/js/bootstrap.js"
