I am trying to install mininet-wifi. After downloading it, I have been using the following command to install it:
sudo util/install.sh -Wlnfv
I specifically needed a Dockerfile file and this is what I have put inside so that it works without errors, I hope it will help someone.
This is Dockerfile file:
FROM ubuntu:latest
RUN apt-get update -y
RUN apt-get install -y python3 python3-dev
WORKDIR /app
COPY . /app
ENV DEBUG=True
EXPOSE 80
To solve the problem of:
E: Unable to locate package python-pip
Run the package update index cmd:
sudo apt update
If not that, then python-pip-whl
(which is also a package installer) is available in the universe
repository, make sure that's installed and then run:
sudo apt-get install python-pip-whl
Pip for Python 2 is not included in the Ubuntu 20.04 repositories.
You need to install pip for Python 2 using the get-pip.py script.
1. Start by enabling the universe repository:
sudo add-apt-repository universe
2. Update the packages index and install Python 2:
sudo apt update
sudo apt install python2
3. Use curl to download the get-pip.py script:
curl https://bootstrap.pypa.io/get-pip.py --output get-pip.py
4. Once the repository is enabled, run the script as sudo user with python2 to install pip :
sudo python2 get-pip.py
Pip will be installed globally. If you want to install it only for your user, run the command without sudo. The script will also install setuptools and wheel, which allow you to install source distributions
Verify the installation by printing the pip version number:
pip2 --version
The output will look something like this:
pip 20.0.2 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
Put python3
instead ${PYPKG}
in line 202, and instead python-pip
in line 596 in file install.sh
of mininet-wifi.
I've found that creating a virtualenv
for Python 2.7 installs also pip
$ virtualenv -p python2 venv
$ . venv/bin/activate
$ pip --version
pip 20.0.2 from /home/.../venv/lib/python2.7/site-packages/pip (python 2.7)
Since Python 2 is past its end-of-life, few packages for Python2 are included in 20.04. You have to install pip
for Python 2 manually:
First, install Python 2:
sudo apt install python2
Then, follow https://pip.pypa.io/en/stable/installing/ , using python2
:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python2 get-pip.py
You can run the second step with sudo
. If you don't use sudo
, you'll need to change PATH
, as suggested by the installation message. Alternatively, and possibly better (since it doesn't change PATH
), use
python2 -m pip
whenever you need pip2.
