Does anyone have an idea about my case?

Answer 1

I've heard that using sudo with pip is unsafe.

Try adding --user to the end of your command, as mentioned here.

pip install packageName --user

I suspect that installing with this method means the packages are not available to other users.

Answer 2

You don't have permission to the Python folder.

sudo chown -R $USER /usr/local/lib/python2.7

Answer 3

Use

sudo pip install virtualenv

Apparently you will have powers of administrator when adding "sudo" before the line... just don't forget your password.

Answer 4

use

sudo pip install virtualenv

You have a permission denied error. This states your current user does not have the root permissions.So run the command as a super user.

Answer 5

It's because the virtual environment viarable has not been installed.

Try this:

sudo pip install virtualenv
virtualenv --python python3 env
source env/bin/activate
pip install <Package>

or

sudo pip3 install virtualenv
virtualenv --python python3 env
source env/bin/activate
pip3 install <Package>

Answer 6

In the case of permission denied error, you just need to go with this command.

sudo pip install virtualenv

sudo before the command will throw away the current user permissions error.

Note: For security risks, You should read piotr comment.

Answer 7

pip is not give permission so can't do pip install.Try below command.

apt-get install python-virtualenv
