python - setup.py & pip: override one of the dependency's sub-dependency from requirements.txt -


i'm working on package , in requirements.txt, have dependency: wikipedia

now, 

wikipedia 1.3 uses requests-2.2.1  while package uses 2.3.0

also, 1 expect, wikipedia-1.3's installation depends on presence of it's dependency.

but, if start new virtualenv , directly include wikipedia in requirements.txt, gives importerror on requests since @ time setup.py runs, requests-2.3.0's setup.py doesn't execute unless others execute: (ref: in figure attached below, there's no 'running setup.py' requests after gets unpacked)

request getting installed not running setup.py simultaneously

(for weird reason, wikipedia's setup.py contains 'import wikipedia', in turn imports it's dependencies before they're installed; passes ci test because it's installing requirements separately through pip , running setup.py)

to on come situation, i've made setup script consisting of:

pip install -r requirements.txt pip install wikipedia pip install -e .
  • this installs requests-2.3.0 , beautifulsoup4;
  • then installs wikipedia (which can run setup.py , installs wikipedia , requests-2.2.1)
  • then 'pip install -e .' option installs package alongwith requests-2.3.0 again.

hence requests-2.3.0 first getting installed, getting replaced older version 2.2.1 , replaced again 2.3.0.

i tried going through various specifications on how overcome confusing. how overcome mess?

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
