Maybe you have installed both python2
and python3
. python3
may have been installed later.
You may try to use pip3
instead of pip
.
First, input the command:
pip3 -V
If you see the version, the pip3
can be used.
Then you can input command line to install nltk
:
pip3 install nltk
I got a way to help you use pip in zsh. We can use nano
to edit files. In nano, ctrl+X to save and exit
In the ~
directory, input the command:
nano .bash_profile
You may see some codes like:
# Setting PATH for Python 3.5
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}"
export PATH
Copy them and paste them to the end of .zshrc
file by using command:
nano .zshrc
Then input the command:
pip -V
If you see the version, pip
can be used.
