From what I\'ve read so far, popper.js is a big pain with Bootstrap 4. I can\'t get it to work. I keep getting this error:

Answer 1

Bootstrap 4 has two dependencies: jQuery 1.9.1 and popper.js 1.12.3. When you install Bootstrap 4, you need to install these two dependencies.

• Install popper.js: npm install popper.js@^1.12.3 --save
• Install jQuery: npm install jquery@1.9.1 --save
• Install Bootstrap: npm install bootstrap@4.0.0-beta.2 --save

For Bootstrap 4.1

• npm install popper.js@^1.14.3 --save
• npm install jquery@3.3.1 --save
• npm install bootstrap@4.1.1 --save
