I searched for the reason and found just this: Bootstrap 4: Uncaught ReferenceError: Popper is not defined
我搜索了原因，发现了这个：Bootstrap 4: Uncaught ReferenceError: Popper is not defined

Popper.jsis not really necessary
Popper.js并不是真正必要的
Bootstrap 4.0.0 release contains 2 new files bootstrap.bundle.jsand bootstrap.bundle.min.jswhich contain Popper.js inside and you really do not need it.
Bootstrap 4.0.0 版本包含 2 个新文件bootstrap.bundle.js，bootstrap.bundle.min.js其中包含 Popper.js，你真的不需要它。
bootstrap.bundle.min.jsis exactly Bootstrap.js + Popper.js.
bootstrap.bundle.min.js正是 Bootstrap.js + Popper.js。
In Bootstrap v4.0.0 documentationit is still mentioned that you need the file for some components
在Bootstrap v4.0.0 文档中仍然提到您需要某些组件的文件
Components requiring JavaScript
- Dropdowns for displaying and positioning (also requires Popper.js)
- Tooltips and popovers for displaying and positioning (also requires Popper.js)
I have not tested it but I think it is not necessary
我没有测试过，但我认为没有必要
Solutions
解决方案
You can use the NPM path 'bootstrap/dist/js/bootstrap.bundle.js'.
您可以使用 NPM 路径“bootstrap/dist/js/bootstrap.bundle.js”。
Or if you finally want to download Popper.js, download the version you need.
或者，如果您最终要下载Popper.js，请下载您需要的版本。

Bootstrap 4.0.0requires popper, so just add "popper.js": "^1.12.9"to the package.json
Bootstrap 4.0.0需要 popper，所以只需添加"popper.js": "^1.12.9"到 package.json
For example dropdown, tooltipsand popoverswon't work:
例如dropdown、tooltips和popovers将不起作用：
https://www.codeply.com/go/CuOfa7UnUA(broken w/o popper)
https://www.codeply.com/go/CuOfa7UnUA（没有 popper 损坏）
Note: As of 4.1, popper.js is only requiredfor dropdowns, tooltips and popovers.
注意：从4.1 开始，只有下拉菜单、工具提示和弹出框需要popper.js。

Have to add "popper.js":"^require_version"into package.json under the dependencies.
必须"popper.js":"^require_version"在依赖项下添加到 package.json 中。
