Error for command dfx canister install --all

Hi everyone,
I am following this tutorial
everything goes well until I try to install cannister.

I put this command:
dfx canister install --all

and I get this error code:
Installing code for canister hello_world, with canister_id ic:8043BE22FCECDF2FA7
An error occured:
reqwest::Error {
kind: Request,
url: “”,
source: hyper::Error(
“tcp connect error”,
Os {
code: 111,
kind: ConnectionRefused,
message: “Connection refused”,

Any ideas what might be the problem?

Thank you very much!

  1. Open a terminal
  2. Head into your project folder
  3. run dfx stop
  4. run dfx start --background
  5. wait for ~ 10 sec
  6. run dfx canister install --all

does this help?


Thanks for the suggestion, when I run dfx start -background it did not recognized argument -background

So I ran only dfx start, this is what I got :frowning: It asked for firewall permision which I granted, and run it again, but with the same message:
/dfinity/hello_world$ dfx start

It‘s supposed to be two dashes: dfx start --background (my phone keeps reformatting this …).
Next thing you should is

  1. open a terminal
  2. head into your project folder
  3. run rm -rf .dfx/state
  4. retry the steps from my previous comment :slight_smile:

There’s also a dfx start --clean option for this.

(Aside, if you want to see what options are available you can always add --help to dfx and any of its subcommands).

here is another one :frowning:

I have tried exactly what you have suggested and a couple more variations… Any other suggestions? :slight_smile:

/hello_world/src/hello_world$ dfx start --background

Did you try this inside your project directory?

Hi Markus

It looks like you might be running this using Windows Subsystem for Linux and saving your project on the mounted Windows drive? If so, this will have issues because of the way WSL handles the mounted drive.

Windows isn’t officially supported yet, but if you:

  1. Use WSL version 2, and

  2. Create your project in the WSL filesystem instead of on the mount, eg in ~/

…you should be able to run it fine.

Some more WSL info can be found in this thread: Dfx on windows for beginners


Great!!! finally it works fine with WSL 2 many thanks!!!


Hello @Ori!

Do you have insights about when Windows will be supported by the DFINITY execution command-line interface?

Meanwhile, thank you for troubleshooting this issue it helped me a lot. :slight_smile:

Best regards,


You’re welcome! No news yet on the Windows release. If you’re a VSCode user their WSL integration makes the experience quite seamless though.
