Just to echo what @skytreader had previously commented, rmvirtualenv is a command provided by virtualenvwrapper, not virtualenv. Maybe you didn't have virtualenvwrapper installed?

See VirtualEnvWrapper Command Reference for more details.

Use rmvirtualenv

Remove an environment, in the $WORKON_HOME.

Syntax:

rmvirtualenv ENVNAME

You must use deactivate before removing the current environment.

$ rmvirtualenv my_env

Reference: http://virtualenvwrapper.readthedocs.io/en/latest/command_ref.html

You can remove all the dependencies by recursively uninstalling all of them and then delete the venv.

Edit including Isaac Turner commentary

source venv/bin/activate
pip freeze > requirements.txt
pip uninstall -r requirements.txt -y
deactivate
rm -r venv/

Simply remove the virtual environment from the system.There's no special command for it

rm -rf venv

from virtualenv's official document https://virtualenv.pypa.io/en/stable/userguide/

Removing an Environment

Removing a virtual environment is simply done by deactivating it and deleting the environment folder with all its contents:

(ENV)$ deactivate
$ rm -r /path/to/ENV

I used pyenv uninstall my_virt_env_name to delete the virual environment.

Note: I'm using pyenv-virtualenv installed through the install script.

if you are windows user, then it's in C:Usersyour_user_nameEnvs. You can delete it from there.

Also try in command prompt rmvirtualenv environment name.

I tried with command prompt so it said deleted but it was still existed. So i manually delete it.

The following command works for me.

rm -rf /path/to/virtualenv

deactivate is the command you are looking for. Like what has already been said, there is no command for deleting your virtual environment. Simply deactivate it!

If you are a Windows user and you are using conda to manage the environment in Anaconda prompt, you can do the following:

Make sure you deactivate the virtual environment or restart Anaconda Prompt. Use the following command to remove virtual environment:

$ conda env remove --name $MyEnvironmentName

Alternatively, you can go to the C:UsersUSERNAMEAppDataLocalContinuumanaconda3envsMYENVIRONMENTNAME (that's the default file path) and delete the folder manually.

step 1: delete virtualenv virtualenvwrapper by copy and paste the following command below:

$ sudo pip uninstall virtualenv virtualenvwrapper

step 2: go to .bashrc and delete all virtualenv and virtualenvwrapper

open terminal:

$ sudo nano .bashrc

scroll down and you will see the code bellow then delete it.

# virtualenv and virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /usr/local/bin/virtualenvwrapper.sh

next, source the .bashrc:

$ source ~/.bashrc

FINAL steps: without terminal/shell go to /home and find .virtualenv (I forgot the name so if your find similar to .virtualenv or .venv just delete it. That will work.
