If you can not find your 'virtualenv' command in the windows console after installing it with pip try this to make your environment:

python -m virtualenv <nameOfEnv>

If you need to use a specific version of python, initialize it like this:

python -m virtualenv <nameOfEnv> -p=<C:/path/to/python/version3.x.x/python.exe>

When using windows for first installation, you can use python from WindowsApp

Run pip uninstall virtualenv and then pip install virtualenv

There are three points that you need to consider:

• Make sure that in the windows PATH variable there is an entry with your python installation and the scripts subfolder eg: C:\Program Files (x86)\Python36-32\ and C:\Program Files (x86)\Python36-32\Scripts\
• When using pip install virtualenv, make sure that you run cmd as administrator. Otherwise, there might an access denied error during installation and virtualenv will not be installed properly.
• Make sure that virtualenv has been installed correctly. Check in the python scripts subfolder - there must exist an .exe named virtualenv.exe. If not, uninstall will pip uninstall virtualenv and install again.

py -3 -m venv venv

try using the above command.

virtualenv venv

will work on only older version of python

Use

python -m venv abc

Where abc is the name of the virtual environment

Run CMD as administrator and then enter

pip uninstall virtualenv

then re-run CMD as administrator and run

pip install virtualenv

To install to a specific folder e.g E:\publish

pip install virtualenv

virtualenv .

Use "py -m virtualenv Your_Folder_Name"

Try to run

    PowerShell.exe -command "./venv/Scripts/activate"

• Step 1: Run pip uninstall virtualenv.
• Step 2: Run pip install virtualenv.
• Step 2.1: Run virtualenv to check if it's now working...
• Step 3: Still not working? Go to your prevouis console log to find where it says "WARNING: The script virtualenv.exe is installed in 'C:\Users\username\AppData\Roaming\Python\Python310\Scripts' which is not on PATH."
• Step 4: Copy the specified path from the warning message.
• Step 5: Search for and open "System Properties" on your PC.
• Step 6: Click the Advance tab, and then the Environment Variables Button on the bottom right.
• Step 7: Click the variable value "Path" and then click edit.
• Step 8: In the Edit Environment variable window, click new then paste your path in any slot.
• Step 9: MAKE SURE you click OK twice and not to just exit out.
• Step 10: Reboot terminal and check again.

For windows First, install -> pip install virtualenvwrapper-win Then setup -> mkvirtualenv myproject Then you see the list of virtual environment To see it you write-> lsvirtualenv For working this environment we write -> workon myproject

Try executing virtualenv.exe from its absolute path, like in my case i found it in C:\Users\<your user>\AppData\Roaming\Python\Python37\Scripts\virtualenv.exe.

I tried this and it worked, here refer the logs as follows:

Using base prefix c:\\users\\<user>\\appdata\\local\\programs\\python\\python37-32 New python executable in C:\somedir\dir2\dir3\ML_1\ml\env\Scripts\python.exe Installing setuptools, pip, wheel... done.

This almost works for all

1. Open Command Prompt, navigate it to the Envs folder, run "env_name\Scripts\activate"
2. Check whether virtualenv is installed or not, if not install it:
   • pip install virtualenv
   • pip install virtualenvwrapper-win
3. Game On. Check on your IDE.

I got this error too but I figure it out. you just have to open PowerShell as administrator and then write following command Set-ExecutionPolicy unrestricted then type A. you are all set! now uninstall the packages and re-install them. Now if you write flask --version or virtualenv --version There will be no error at all.

Windows

If you want to use the lsvirtualenv command with virtualenv, follow the steps below.

Incorrect:

python -m pip install virtualenv 

python -m pip install virtualenvwrapper

Correct:

python -m pip install virtualenv

python -m pip install virtualenvwrapper-win

Basic Uses

Then, to create a virtual environment:

mkvirtualenv youVirtualEnvironmentName

• It will be activated automatically:

  C:\Users\YourUserName (youVirtualEnvironmentName) λ
  

First, to access an existing virtual environment:

C:\Users\YourUserName λ workon youVirtualEnvironmentName

Next, to exit the currently active virtual environment:

C:\Users\YourUserName (youVirtualEnvironmentName) λ deactivate

Finally, to list all your virtual environments:

C:\Users\YourUserName λ lsvirtualenv

dir /b /ad 'C:\Users\YourUserName\Envs'
==================================================================
youVirtualEnvironmentName

I had this same issue using python3.

The solution was to use the python3 -m virtualenv . command.

Make sure that virtualenv has been installed correctly. Check in the python scripts subfolder - there must exist an .exe named virtualenv.exe. If not, uninstall will pip uninstall virtualenv and install again.

1)First Way as

python -m virtualenv name_of_virtual_environment

OR

2)Second Way as

py -3 -m venv name_of_virtual_environment

You just need to reinstall virtualenv. First of all you need to uninstall virtualenv with this command.

pip uninstall virtualenv

Then just reinstall with this command.

pip install virtualenv

Solution-1: python -m venv name_of_virtual_environment

E:\code\python\tvenv>python -m venv myenv

E:\code\python\tvenv>cd myenv\Scripts\

E:\code\python\tvenv\myenv\Scripts>activate.bat

(myenv) E:\code\python\tvenv\myenv\Scripts>deactivate.bat
E:\code\python\tvenv\myenv\Scripts>

Solution-2: py -3 -m venv name_of_virtual_environment

E:\code\python\tvenv>py -3 -m venv myenv

E:\code\python\tvenv>cd myenv\Scripts

E:\code\python\tvenv\myenv\Scripts>activate.bat

(myenv) E:\code\python\tvenv\myenv\Scripts>deactivate.bat
E:\code\python\tvenv\myenv\Scripts>

1. Open a cmd or ps with run as admin.
2. Now run pip uninstall virtual.
3. pip install virtual.
4. Done :D

Implementation:

1. Go to the directory where you want to make a python env.
2. type: virtualenv myEnv
3. beep bop boop done.

ps: Always use cmd or powershell with run as admin if you're installing some new package.
