Question:
I tried installing uvicorn on the system via pip3 which worked, however i am unable to run the same from the command line. Any pointers as to how to resolve this?

Answers:
It looks like your bin dir is not on $PATH.
Execute it directly:
/home/vhawk19/.local/bin/unvicorn
Or just add to path first:
export PATH=$PATH:$HOME/.local/bin
You can put this in your shell rc file.
Check your PATH environment variable. It should include the path to unicorn package too.
Not sure about the linux paths, but in windows you need to have these two in your Path environment variable.

After creating new virtual environment if you get
Requirement already satisfied
forcefully uninstall all the packages by executing:
pip freeze > requirements.txt
pip uninstall -r requirements.txt -y
Now check the packages using:
pip list
if uvicorn is present in requirements.txt, commands such as uvicorn app.main:app –reload
will work.
If not install uvicorn using
pip install uvicorn
& then try executing uvicorn app.main:app –reload
Now you should be able to find No packages, or some default packages such as pip, wheel, etc.
Reinstall all the packages from requirements:
pip install -r requirements.txt
You can use the command below directly from the cmd. The path is fine for my case, but I still get the error using uvicorn command.
python -m uvicorn
I ran into the same problem.
I am using pyenv-win for managing Python versions.
The following command managed to fix the issue
$ pyenv rehash
1.First know where the uvicorn is located. You can know this by typing command
$locate uvicorn
Now,select the path that looks something like
/home/username/.local/bin/uvicorn
2.Then,type command
$ls -a
here, you can see a hidden file named .bashrc and .bash_profile. Now,we have to add our uvicorn path in ths .bashrc file or in .bash_profile . For this we use nano text editor and write the following in .bashrc and saved it
$nano .bashrc
export PATH:$PATH:/home/username/.local/bin
i recently install fastapi,uvicorn and tried to run
uvicorn main:app --reload
I am using zsh (shell type does not matter) and pyenv for virtual environment
got the same trouble (zsh: uvicorn command not found)
Solution which worked for me
python -m uvicorn main:app --reload
Why it worked
its because when we install uvicorn it install some system binaries which we may have to add to the path for the terminal to catch
else, we need to let the the terminal know about the binaries through python
One very common cause of this issue is that the uvicorn server is not being run from root. Do the following steps to solve this :
- Login as root user using command :
sudo -i
- Navigate to you virtual env location and activate it
- Now restart the uvicorn server
sudo pip install and pip install might be in two different locations.
Fisrt step tried to install uvicorn:
pip3 install uvicorn
then run this command:
python3 -m uvicorn main:app --reload
works.
