问题 In R I can use install.packages("pkgName") to install a new package no problems. But when I tried python and do pip install package it fails with error Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError(': Failed to establish a new connection: [Errno 11004] getaddrinfo failed',)': /simple/pyarrow/ I think it's because pip doesn't know how to automatically detect the proxy (that's gets set in Internet Explorer) like R

问题 Every time I try to pip install something, this happens: Lucianos-Mac:test luciano$ pip install torch Collecting torch Could not install packages due to an EnvironmentError: Could not find a suitable TLS CA certificate bundle, invalid path: /Users/luciano/Applications/NextGIS/Library/Frameworks/openssl.framework/Resources/ssl/certs/cert.pem The path it references was created when I installed the gdal package from nextgis.com, which I later deleted, so the NextGIS directory does not exist.

问题 I was having difficulty installing a package because of a ModuleNotFoundError for wrapt and so I removed and tried to reinstall wrapt. I ran the uninstall once, and wrapt was removed from one location. I tried to install, but the requirement was already satisfied, so I uninstalled wrapt again. See the three commands below: Found existing installation: wrapt 1.12.1 Uninstalling wrapt-1.12.1: Would remove: c:\users\me\appdata\roaming\python\python38\site-packages\wrapt-1.12.1-py3.8.egg-info c:

问题 EDITED I'm very new to python and have a probably super basic question. I've installed Jupyter Notebook by installing anaconda which includes python 3 by default. Now I want to use an external toolbox which still works with python 2.7, so I'm trying to get e kernel with python 2.7 as suggested here. In the Anaconda Prompt I'm typing python2 -m pip install ipykernel python2 -m ipykernel install --user But it says that it couldn't find the command "python2". Any idea? 回答1: I had the same issue.

I don't even see it when I inspect the wheel file directly using the suggestion here. Question : How do I check the signature of the wheel file as the

问题 I found that python can use pyproject.toml to list dependencies instead of requirements.txt file. It's more convenient and is very similar to package.json for node.However, I could not find a documentation to init the pyproject.toml file much like the npm init command. How to autogenerate the file with virtualenv or pip? also, is there a way to autoupdate the toml file, as the packagaes get installed, much like npm --save tag, that saves the package to the package.json as its installed? 回答1:
