+
+1. As local server using the BlackConnect plugin
+1. As external tool
+1. As file watcher

+The first option is the simplest to set up and formats the fastest (by spinning up

-**I get an import error when using _Black_ from a virtual environment**: If you get an

 ```
 ```

-
-Then you need to install `typed_ast` and `regex` directly from the source code. The
-error happens because `pip` will download [Python wheels](https://pythonwheels.com/) if
-they are available. Python wheels are a new standard of distributing Python packages and
-packages that have Cython and extensions written in C are already compiled, so the
-installation is much more faster. The problem here is that somehow the Python
-environment inside Vim does not match with those already compiled C extensions and these
-kind of errors are the result. Luckily there is an easy fix: installing the packages
-from the source code.
-
-The two packages that cause the problem are:
-
-- [regex](https://pypi.org/project/regex/)
-- [typed-ast](https://pypi.org/project/typed-ast/)
-
-Now remove those two packages:
-
-```console
-$ pip uninstall regex typed-ast -y

-you need to have the GCC compiler and the Python development files installed (on
-Ubuntu/Debian do `sudo apt-get install build-essential python3-dev`).
