instructions.md

uninstall the old version of mypy so that the mypy command won't point to the old one

pip3 uninstall mypy

use the version of typed_ast from this PR: python/typed_ast#22

pip3 install -e git+https://github.com/kirbyfan64/typed_ast@fstring#egg=typed_ast

install the version of mypy from @achauve's PR

pip3 install -e git+https://github.com/achauve/mypy@handle-f-string-without-error#egg=mypy

MyPy should be working. Test it out.

echo 'f"{foo{1}bar{2}"' > fstring_test.py
mypy --fast-parser --python 3.6 fstring_test.py
