Could not resolve “@popperjs/core”

I keep getting this error on running dev. Albeit it doesn’t appear I’m getting it in production.

I run.

npm run dev

Then everything appears to be ok, with the standard message like this from vite.

  vite v2.9.9 dev server running at:

  > Local: http://localhost:3000/
  > Network: use `--host` to expose

  ready in 740ms.

But then, once I navigate to the site to check things out.

X [ERROR] Could not resolve "@popperjs/core"

    node_modules/bootstrap/dist/js/bootstrap.esm.js:6:24:
      6 │ import * as Popper from '@popperjs/core';
        ╵                         ~~~~~~~~~~~~~~~~

  You can mark the path "@popperjs/core" as external to exclude it from the bundle, which will
  remove this error.

…and this error annoyingly crops up.

11:36:23 PM [vite] error while updating dependencies:

...

…and on and on and on goes these errors. For whatever reason, even though npm install has been run once just get to the point of running npm run dev, there needs to be a subsequent, specifically executed npm install @popperjs/core to install this particular dependency that throws this error.

So that’s it, that’s your fix. Cheers!

The Method I Use Setting Up a Dev Machine for Node.js

UPDATED: April 4th, 2019 and again on March 17th, 2022

It seems every few months setup of whatever tech stack is always tweaked a bit. This is a collection of information I used to setup my box recently. First off, for the development box I always use nvm as it is routine to need a different version of Node.js installed for various repositories and such. The best article I’ve found that is super up to date for Ubuntu 18.04 is Digital Ocean’s article (kind of typical for them to have the best article, as their blog is exceptionally good). In it the specific installation of nvm I’ve noticed has changed since I last worked with it some many months ago.

My Node.js Story

Once upon a time in a part of the tech universe far far away, there was a general consensus to block all JavaScript from browser execution. It was the way things were because JavaScript was seen as harmful. You see, the early miscreants of that time had used JavaScript to write all sorts of problematic code that would attack, steal, or otherwise undermine the data one sent across and received on the internet. This is the time I could have started learning JavaScript, but because of its horrid reputation I stayed far away and wrote C, C++, C#, Java, and event some RPG, COBOL, Pascal, and some other code. It was glorious, and the languages were beautiful in their own ways, while JavaScript was shunned by almost everybody in that tech universe! **

Today, things aren’t all that much different, but we make it easier for the whole horde of miscreant scripters to write problematic code in JavaScript. The difference is we allow it everywhere and just try to catch it and prevent execution. Thus, different, but the same, it’s a crazy world we live in.

I started picking up a little JavaScript at the tail end of 2007, when the “JavaScript: The Definitive Guide” was the top book to delve deeply into using JavaScript. It wasn’t another year until the seminal “JavaScript: The Good Parts” cut down the size of what one really needed to delve into by removing the cruft and focusing on the good parts. Slowly, JavaScript was finally starting to take shape as something useful.

Writing JavaScript at this time was a mutant challenge of having it look like Java while being organized like a trash pile of scripts that had no way to manage dependencies or otherwise. I mean, NPM was years away from existing, and really the concept of libraries in JavaScript seemed to be a foreign concept at the time.

2008 rolled around, “JavaScript: The Good Parts” came out, the changes started rippling through the industry and as traction started to mount. The penultimate event occurred the following year in 2009, which at the time almost nobody noticed. Dahl started Node.js at Joyent to enable server side JavaScript code use. At the time, many were flummoxed by the notion, weren’t confident in the single threaded event loop, and overall its release and the project continuing were in jeopardy from this point.

But the project continued and persisted!

__2 “Starting a Basic Loopback API & Continuous Integration”

In this article Keartida is going to dive into setting up a basic Loopback API project and get a build of that project running on a continuous integration service. In this example she’s going to get the project setup with Codeship.

Prerequisites:

  • Be sure, whichever system you are using, to have a C++ compiler installed. For Windows that usually means installing Visual Studio or something, on OS-X install XCode and the Developer Tools. On Ubuntu the GCC compiler and other options exist. For instructions on OS-X and Linux check out installing compiler tools.
  • Ubuntu
  • OS-X
  • For windows, I’d highly suggest setting up a VM of Ubuntu to do any work with Loopback, Node.js, or follow along with this material. It’s possible on Windows, but there are a number of things that are lacking. If you still want to make a go of using Windows, here are some initial setup steps here.

Nice to Haves:

  • git-flow – works on any bash, handles the branching and merging. Very nice scripts to have.
  • bashit – Adding more information to the bash prompt (works on OS-X, not Ubuntu or Windows Bash)

__1 “Getting Started, Kanban & First Steps for a Sharing App”

This is the first (of course the precursor to this entry was the zero day team introduction article) of an ongoing series I’m going to put together. I’m going to write this series from the context of a team building a product. I’ll have code samples and more as I work along through the material.

The first step included Oi Elffaw having a discussion with the team to setup the first week’s working effort. Oi decided to call it a sprint and the rest of the team decided that was cool too. This was week one after all and there wasn’t going to be much else besides testing, research, and setup that took place.

Prerequisites

Before starting everything I went ahead and created a project repository on github for Oi to use waffle.io with. Waffle.io is an online service that works with github issues to provide a kanban style inferface to the issues. This provides an easier view, especially for leads and management, to get insight into where things are and what’s on the plate for the team for the week. I included the default node.js .gitignore file and an Apache 2.0 license when I created the repository. Github then seeds the project with a .gitignore, README.md and the license files.

After setting up the repository in github I pinged Oi and he set to work after the team’s initial meet to discuss what week one would include. Continue reading “__1 “Getting Started, Kanban & First Steps for a Sharing App”” →
