Python Solutions
Solution 1 - Python
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
Solution 2 - Python
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 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.

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

Well, in my case the problem had a different cause, the Windows path Length Check this.
I was installing a library on a virtualenv which made the path get longer. As the library was installed, it created some files under site-packages. This made the path exceed Windows limit throwing this error.
Hope it helps someone =)

As a windows user, run an Admin powershell and launch :
python -m pip install --upgrade pip
Solution 7 - Python
I just ran the command with sudo:
sudo pip install numpy
Bear in mind that you will be asked for the user's password. This was tested on macOS High Sierra (10.13)

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
Solution 9 - Python
If you are already using an virtual env on ubuntu and if you get this error,then navigate to your virtual env folder.If you see a lock symbol like:
Then you don't have the appropriate permission as a user to pip install inside this.Hence change the permission of the venv folder using this command:
sudo chown -R $USER path/to/venv
Now switch to the venv and install your package.

On Windows this has worked for me. From the command line, specify the path to the exe for Python: & "C:/Program Files (x86)/Python37-32/python.exe" -m pip install --upgrade pip --user

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
