how can i solve this? i have already tried to uninstall python3, and reinstall it through home-brew, and reinstall Pip3, Requests, and beautifulSoup again, but it still shows me the error. Please assist to solve this.

Have you tried this?

i needed opencv libarary for the code so i installed opencv using python3
pip3 install opencv-python
but the code requires and compatible with python 2
so i tried to install the library using just pip instead of pip3
when i tried to install opencv using pip it is saying

You are troubleshooting with your versions. You say your code is not workable for python3 so you tried to run it on python2. It seems that your pip is linking against your python 3.6 Version instead of python 2.X. The best way to handle these problems are virtual environments:
Python 3.X: https://docs.python.org/3/library/venv.html
Python 2.X: https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/
Inside an activated Environment the command python and pip are linked to the version of the environment.

from google.cloud import language ModuleNotFoundError: No module named 'google.cloud'

I had a code that I was able to run last year using Google Cloud Natural Language. I am not able to this year due to a library problem. I used the following methods to install it. However, not successful. How should install it?
[jalal#goku sentiment]$ pip install --user --upgrade google-cloud

A little about my system setup:
$ which python
/scratch/sjn-p3/anaconda/anaconda3/bin/python
$ python
Python 3.6.4 |Anaconda custom (64-bit)| (default, Jan 16 2018, 18:10:19)
[GCC 7.2.0] on linux
$ lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description: CentOS Linux release 7.6.1810 (Core)
Release: 7.6.1810
Codename: Core
Also, I find it very weird when I am installing the pip package with Anacoda pip why does it install it into native Python and not Anaconda Python?
$ /scratch/sjn-p3/anaconda/anaconda3/bin/pip install --user --upgrade google-cloud
Requirement already up-to-date: google-cloud in /home/grad3/jalal/.local/lib/python3.6/site-packages (0.34.0)
The issue is you are using the --user flag and pip but wish to run the Anaconda distribution of Python.
If you do python -c 'import site; print(site.USER_BASE)' from the CLI it will return /home/grad3/jalal/.local hence why packages are installed there when you pass the --user flag to pip. Since you want to use the Anaconda distribution you should stay consistent and use their version of a package manager, which would be conda in this case, which you can find about more --> here.
However, I highly recommend using virtual environments so that this issue can be avoided in the future. You can find out more about Anaconda virtual environments over --> here.
If you wish to keep using pip along with Anaconda you can modify your target directory in the ~/.pip/pip.conf file to point at the location you want. Probably something along these lines will work:
[global]
target=/scratch/sjn-p3/anaconda/anaconda3/lib/python{version}/site-packages
Solved the problem by the following command. You have to install the specific product from the Google Cloud (in this case Natural Language):
$ pip install --user --upgrade google-cloud-language

Python: "No module named 'requests' " after pip3 install requests in pipenv

I'm trying to install the library requests in pipenv, with Python 3. I've tried:
pip install requests, before forgetting that pip installs only for Python 2, leading to,
pip3 install requests, which returns assuringly
Requirement already satisfied: requests in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (2.19.1)
Requirement already satisfied: idna<2.8,>=2.5 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from requests) (2.7)

Requirement already satisfied: chardet<3.1.0,>=3.0.2 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from requests) (3.0.4)
When I run my python files with import requests, everything works, but when I run pipenv run python mypythonscript.py, I get the error ModuleNotFoundError: No module named 'requests'. Please advise what I'm missing.
The problem here is that pip3 install requests runs outside of pipenv's virtualenv, it is installed outside of virtualenv, and thus requests library is not found from code running inside the virtualenv.
The correct way to install the library into the virtualenv is pipenv install requests, which will also add requests to your Pipfile. If you want to install it temporarily without saving into the Pipfile, you can run pipenv run pip install requests.

This folder is also the system Python, not the virtualenv, if you are using one. You can set virtualenv to use the system installed packages, but again, that path is not Python3.
The root issue is that using sudo executed pip under a different user account
Either use Python2, or install using pip3 or python3 -m pip and you shouldn't need sudo
