如何正确安装 fastapi？

Question

I want to install fastapi using pip in VsCode using

pip install fastapi[all]

but I am getting this huge error. What am I doing wrong?

Answer 1

u install 'uvicorn' differently?

• Try to do these commands:

  pip install "uvicorn[standard]"

• The library needs the VC v14+ runtime library, not VS build tools. You can get the runtime from the MS downloads page. Install the VS 2015/2017/2019 redist as it is the latest version.

Answer 2

Actually, this post worked. Thank you, everyone!
pip install --only-binary:all: fastapi[all]

Answer 3

You can install poetry, which is a new python dependency management tool (equivalent to yarn / npm for Node.js and bundler for ruby) that makes it easier to manage dependencies in your project and beats pip by a mile. It is also very easy to install.

# install command pip install poetry

# Verify the installed version poetry --version

poetry add fastapi uvicorn[standard]
# zsh USE:   poetry add fastapi "uvicorn[standard]"

enter image description here

When poetry installs the dependencies, they are documented in the pyproject.toml file.
