Could not install packages due to a “Environment error :[error 13]: permission denied : 'usr/local/bin/f2py'”

Question

I am trying to install numpy on macOS X but after executing the command pip install numpy I am getting the error:

Environment error :[err

Answer 1

This worked for me.

pip3 install --user package-name  # for Python3
pip install --user package-name   # for Python2

The --user flag tells Python to install in the user home directory. By default it will go to system locations. credit

Answer 2

It is always preferred to use a virtual environment ,Create your virtual environment using :

python -m venv <name_of_virtualenv>

go to your environment directory and activate your environment using below command on windows:

env_name\Scripts\activate.bat

then simply use

pip install package_name

Answer 3

I am also a Windows user. And I have installed Python 3.7 and when I try to install any package it throws the same error that you are getting.

Try this out. This worked for me.

python -m pip install numpy

And whenever you install new package just write python -m pip install <package_name>

Hope this is helpful.

Answer 4

pip install --user package-name

Seems to work, but the package is install the the path of user. such as :

"c:\users\***\appdata\local\temp\pip-req-tracker-_akmzo\42a6c7d627641b148564ff35597ec30fd5543aa1cf6e41118b98d7a3"

I want to install the package in python folder such c:\Python27. I install the module into the expected folder by:

pip install package-name --no-cache-dir

I too had to face the same problem. This worked for me. Right click and run as admin than run usual command to install. But first run update command to update the pip

python -m pip install --upgrade pip

I had the same problem for different package. I was installing pyinstaller in conda on Mac Mojave. I did

conda create --name ai37 python=3.7
conda activate ai37

I got the mentioned error when I tried to install pyinstaller using

pip install pyinstaller

I was able to install the pyinstaller with the following command

conda install -c conda-forge pyinstaller
