Error while installing Flask in virtualenv - windows
I had this problem. Downgrade your version of Setuptools.In your virtualenv:
pip install setuptools==21.2.1pip install flaskThis should do it. The problem is something to do with syntax that I don't get.
This has driven me crazy too. Follow these steps:1) system wide pip uninstall flask2) create virtualenv in your app folder3) DON'T USE pip, instead easy_install flask4) Then use pip to install all other dependencies.
This worked for me, I don't know why but it solved what was a very tiresome problem.
