pvp VS npm

I use a small shell script I wrote in jest a year ago (https://github.com/senko/pvp), it boils down to virtualenv and pip, and it basically solves all Python package management issues for me.

I was burned by pipenv before (naively trying to use it because a certain prominent member of Python community hyped it up, and I hadn't known he'd gone off the rails). I can find no redeeming qualities to it whatsoever, and it scarred me enough that I don't want to touch other newer tools (poetry, pdm, whatever) with a 10ft pole.

I find solace in pip and virtualenv just working and not trying to be too clever.

I pin all my immediate reqs, and if there's a conflict with indirect deps (which happened maybe once or twice), I figure out the version I need and pin that manually.

For packaging I rely on specialized tools that do just that (build, twine), and don't need one-with-everything spaceship of a tool.

I also develop in Node and have suffered much more grief by npm. I lost count of the number of times where I had to rm-rf node modules and npm cache, rerun and hope for the best.

I only use and swear by pvp.

So I got y'all a little early Xmas present: PvP, the Python package manager to end all Python package managers!

The fact that JSON doesn't support comments is so annoying, and I always thought that Douglas Crockford's rationale for this basically made no sense ("They can be misused!" - like, so what, nearly anything can be misused. So without support for comments e.g. in package.json files I have to do even worse hacky workaround bullshit like "__some_field_comment": "this is my comment"). There is of course jsonc and JSON5 but the fact that it's not supported everywhere means 10 years later we still can't write comments in package.json (there is https://github.com/npm/npm/issues/4482 and about a million related issues).

Things like the sparkline charts on npmjs (e.g. https://www.npmjs.com/package/npm ) are interactive SVGs. I think they're pretty common for data visualizations of all kinds

I actually did a POC 7 years ago about this - https://github.com/tanepiper/steal-ur-stuff

It was reported to npm at the time, but they chose to ignore it - https://github.com/npm/npm/issues/17724

Every time this pops up, I'm reminded of the day that the NPM registry started returning 418 responses.

I remember being at a training course that day and my manager asking me what we could do to fix it because our CI was failing to pull dependencies from NPM.

Trying to explain that NPM was returning a status code intended as an April Fools joke and which was never meant to see the light of production was quite difficult

https://github.com/npm/npm/issues/20791

I should really get around to how I discovered this 6 years ago and still nothing done about it

Whenever something like this comes up I usually have to tap the sign (and the original report)

NPM is not "Node Package Manager". https://www.npmjs.com/package/npm

> which can be overriden with env setting

Support for this is not great. Lots of packages still don't support this properly. My experience matches the 2015 comment https://github.com/npm/npm/issues/775#issuecomment-71294085

> Not sure why "symlinks" would be involved.

If you make your node_modules a symlink, multiple packages will fail. Even if you're not interested in doing that, others are.

Unless you change your node / gyp version. It doesn't really have a concept of runtime version. You can restrict it, but not have two concurrent versions if they conflict.

[email protected] was released in May 2017 and it seems to address many of the issues that Yarn aims to solve. Do keep an eye on it!

I think it's had been supposed to do that since forever. Apart from some bug in npm 5.3. Are you sure your package-lock versions actually conform to the semver ranges in your package.json?
