HI I am getting an error while installing virutal environment or any installation, Can you please help me. Please find the screen shot below

I have tried to rectify by searching and installing all the related fixes shown in the Internet.

@guruvishnuvardan, I have a feeling this is related to you trying to install virtualenv as a root.

Unlike apt-get, you shouldn't use sudo to use pip

When I installed without sudo I got an error. I had to use the --user option.
Error:

pip3 install virtualenv

am using mint rosa and whenever I try to install the venv, all goes well until I get msg E: unable
to locate package python3-env. Am stuck at this point. I really need help

Thanks --user worked for me..

Steps I followed:

sudo apt-get install python3-pip
pip3 install virtualenv 
virtualenv venv 

But I get error as:

The program 'virtualenv' is currently not installed. You can install it by typing:
sudo apt install virtualenv

I was getting the following:

Exception:

Since I don't mind to use 2.7, this is what ended up working for me:

sudo apt install python-pip python-distutils-extra python-elib.intl
sudo pip install virtualenv 

Something similar might be available for python3

pip installed binaries are located at ~/.local/bin, so you need to add that to your path.

echo "export PATH=~/.local/bin:$PATH" > ~/.profile 
source ~/.profile

Just in case you are on running vagrant add '--always-copy'

Thank Y'all! This was helpful

How do you make virtualenv global?

virtualenv are not intended for global thing. If you want some dependency on global access, they are already @MohammeNagdy

Yeah...
Just:
mkdir project
cd project
sudo apt-get install python3-pip
pip3 install virtualenv
python3 -m venv myenv

then you start installing all the libraries you need for that project

I dob't care, guis) Im protecting as you are, but you can see it

I don't have a terminal

If you have Python3.3 and newer version, venv is already there. Here how it worked for me without installing virtualenv.

python -m venv .

python -m venv without period didn't work

ls command displayed bin include lib share and pyvenv.cfg files

After that I activated the venv and installed Django. And then run the server and created the project mamusite

OSError: [Errno 9] Bad file descriptor
my error while creating the virtual env

Steps I followed:

sudo apt-get install python3-pip
pip3 install virtualenv 
virtualenv venv 

But I get error as:

The program 'virtualenv' is currently not installed. You can install it by typing:
sudo apt install virtualenv

use sudo apt-get update then use sudo apt-get install virtualenv

OSError: [Errno 9] Bad file descriptor
my error while creating the virtual env

could you please provide more details, like

• what OS are you using

• what command did you run and displayed an error

• do you have any screenshots you can share

can anyone please tell me why i cant use virtualenv in this directory? i am using ubuntu LTS 20.04

@mursalatul could you please name dele to venv your command should look like this source venv/bin/activate
you can create venv using this command python3 -m venv venv

it is telling permission denied what to do ?
