I am setting up a server, and trying to run python code. Painfully installing python3.X; and just realized I have to install all standard/required python modules one-by-one.
Is there a way to easily install the latest set of standard python modules? I don't mean using a requirements.txt file.
Standard modules are : numpy, pandas, scipy, scilearn, requests etc... But I know there must be alot of useful python modules.
So, I tried googling and cannot seem to find a public way to easily install a whole list

I'm pretty new with NodeJS and I'm trying to use a module called "updated-node-msmq" (from this repository) in my project but getting an error.
What I've done:
I opened a new folder for the project.
I used the command "$ npm install --save updated-node-msmq" and got some warnings (Screenshot attached).
When I try to use the module according to the README, and run my "test.js" file I got the following error here in the screenshot).
I am using version 14.16.0 of NodeJS and after trying to fix this myself I realized that probably the problem is that the module was built for older versions of NodeJS.
I understand that low version is not a recommended solution, but I have no clue how to update a module.
Help / guidance in solving the problem?
Thanks in advance everyone!
Why are you using updated-node-msmq? That package seems like a mess, and the errors you are getting is because the whole module is written with ES2015 but doesn't seem to have been transpiled to node.js compatible code before published to NPM.
I'd advise you to use a tried and tested module for MSMQ first and foremost.
EDIT: Seems like the author fucked up in the 0.2.0 version. You could use the 0.1.9 (by instead using npm install updated-node-msmq#0.1.9 but that one is 3 years old.
OSError: Python library not found: libpython3.8m.dll, libpython3.8.dll, python38.dll, libpython38m.dll, libpython38.dll
This would mean your Python installation doesn't come with proper library files.
This usually happens by missing development package, or unsuitable build parameters of Python installation.
How do I solve this issue? I am trying to compile my stock market simulator into an exe but I keep on getting this issue. I have tried various solutions, but all of them have no worked.
I am trying to install "threepenny-gui", I simply do it by
cabal install threepenny-gui
It is a school project that I have to use it and you can find the start code here.
After I have installed it and run Calculator.hs without changing anything I get the error

Perhaps you meant Data.Version (from base-4.8.2.0)

I read here in section 4.1 that
This happens when you install a package globally, and the previous packages were installed locally.
But does not give any real solution. How should I install it correctly? Have been having similar problems when installing other modules.
I'm trying to figure out how to use external javascript libraries in the Atom editor. I used npm to install the momentjs library, since Atom uses node. However, I'm puzzled as to what to do now? I can't find a way to use the library in Atom.
I thought that I could go to the Atom init.coffee file and do a require "moment" (also tried require "momentjs") but nothing seems to work.
The whole reason behind this is so I can use some javascript libraries for formatting dates in a snippet (I have another SO question about that which I'll close if this solves it).
But this question is a general question about installing and running javascript libraries in Atom. I've looked through the Atom docs and Googled, but I can't find a good answer. I figured something like this would be pretty easy?
As Atom bundle its own node version (and thus is not using your global version(s)) it won't load globally installed modules through require.
However, the require method supporting absolute paths, you can still load any module if you know it's absolute path, which shouldn't be a problem in your specific case.
In your init script you can write:
momentjs = require('/path/to/momentjs')
But beware of modules that ships with binaries. Atom is using node 0.11.13 so if the module you're trying to require have been installed for a different version you'll get a Error: Module did not self-register.. In that case I'm afraid the only solution would be to install the module as a dependency of an Atom package (as suggested by #nwinkler).
You should be able to do the following when developing your own package:
Install moment using npm install --save moment - this will install the moment.js library as a dependency and register it in the package.json file
In your library, import it in your lib file:
moment = require 'moment';
myDate = moment().format();
Then you can use the moment object to format your timestamps.
All of this will only work if you're doing your own package, of course. Not sure if this will work with simple snippets as well.
I'm building a nodejs application that needs to run on a Windows server. I've managed to get almost everything working, but I've ran into a problem with the postgresql driver. BrianC has a pure javascript implementation of the node-postgres that I would like to use to avoid having to build the postgres driver.
Is there a way for me to alias node-postgres(npm:pg) to node-postgres-pure(npm:pg.js) so that any dependent package that tries to install and resolve pg will install and resolve pg.js instead?
Thanks
Take a look at node-pg-pure-alias.
It's a bit of a hack, but the idea is to get a package that calls itself 'pg' installed into your node_modules folder. Then, that 'pg' library can export the "real" library.
See #it's not in npm! if you're concerned about depending on a package that's not in the official npm repository.
Disclaimer: I created node-pg-pure-alias. (All ten lines of the package.json, that is.)
