pip install flask

Hi, @banpie it seems you have both Python 2 and 3 installed in your system. When you are running

pip install flask

These packages are being installed in python2.7 which comes by default in MacOS So you can try

# to download a single package
pip3 install flask
# or to download all the packages from requirements.txt
pip3 install -r requirements.txt    # (This should install all the modules in Python3)

# you can run settings.py in python 3
python3 settings/settings.py

I use this cool tool to manage several python versions on my machine https://github.com/pyenv/pyenv, you can set a default global python version or a local python version for a project as well.

Cheers ANk

Thanks for your reply. I think I was using python 3.6 before, as I have add those code to the bash_profile file:

alias python=”/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6”

and I also have tried you solution, but got those:

pip3 install flask

Requirement already satisfied: flask in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages
Requirement already satisfied: Jinja2>=2.10 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from flask)
Requirement already satisfied: itsdangerous>=0.24 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from flask)
Requirement already satisfied: Werkzeug>=0.14 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from flask)
Requirement already satisfied: click>=5.1 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from flask)
Requirement already satisfied: MarkupSafe>=0.23 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from Jinja2>=2.10->flask)
You are using pip version 9.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

then

pip install --upgrade pip
Requirement already up-to-date: pip in /usr/local/lib/python2.7/site-packages (18.1)

but, when i use python3 settings/settings.py， it did works.

Better to use pip3 for Python3+ version

Python2 Sysntax : pip install flask Python3+ Sysntax : pip3 install flask

when changing the env to use python2 I get this when trying to run empire

Traceback (most recent call last): File "./empire", line 5, in from flask import Flask, request, jsonify, make_response, abort, url_for ImportError: No module named flask

When running regular using just python instead of 2 I get this File "/opt/Empire/./empire", line 35 print '[*] Fresh start in docker, running reset.sh for you' ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

I see alot of people been reporting this issue using different thread sites. Is this thing broken due to new kali linux?
