Why User site-packages are not visible in virtualenv?

Question

While installing the nltk module, one of these prerequisites, using the commande pip install --user -U nltk in a venv called dl4cv, I got the error :

(dl4cv) hdafa@hdafa-HP-ProBook-450-G5:~$ pip install --user -U nltk ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv. Any idea to make thse tools visible in the venv, so I can install nltk in dl4cv ?

Answer 1

I don't think you need the --user argument while a venv is activated.

Simply run pip install nltk
