Unable to install DFINITY Canister SDK on Ubuntu

Question

I'm following the steps found here to install DFINITY Canister SDK.
When I run the below command, directory dfx (under /bin) is not created and subsequently the dfx command is not recognized:

adel@adel-VirtualBox:~$ sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"

Answer 1

From the output of the install command it looks as if dfx is installed in /home/adel/bin/dfx. Can you verify that:

1. dfx is indeed there?

test -e /home/adel/bin/dfx && echo yay found it || echo oh no

If not, it looks as if the install didn't work.

If yes, you can run it directly:

"$HOME/bin/dfx" --version

2. Check that your path includes "/home/adel/bin"

echo "$PATH" | tr : "\n" | grep "$HOME/bin"

If not, you can add it with:

echo 'export PATH="$PATH:$HOME/bin"' >> "$HOME/.bashrc"

. "$HOME/.bashrc"

dfx --version

Answer 2

The export command you provided appends the /home/adel/bin/dfx directory to the end of the existing PATH variable. However, there's a common misunderstanding in your export command. You should include only the directory path in the PATH variable, not the full path to the executable (/home/adel/bin/dfx).

Here's the correct export command:

export PATH=$PATH:/home/adel/bin

This command adds the /home/adel/bin directory to the end of the PATH variable. After making this change, you should be able to run dfx from any directory in your terminal.

After modifying the PATH, either restart your terminal session or run the following command to apply the changes:

source ~/.zshrc

Now, you should be able to execute the dfx command without specifying the full path:

dfx

Make sure that the dfx executable has the execute permission (chmod +x /home/adel/bin/dfx) and that the dfx binary is indeed located in the specified directory. If the issue persists, you might also want to check for any aliases or functions that might affect the command resolution.

Answer 3

Issue I faced below issue even after exporting path as mentioned below.

export PATH=$PATH:/home/*****/bin/dfx

Faced the same issue:

dfx --version
Command 'dfx' not found, did you mean:
  command 'fx' from snap fx (24.1.0)
  command 'dfix' from snap dfix (0.3.5)
  command 'dex' from deb dex (0.9.0-1)
  command 'dx' from deb dx (1:4.4.4-15)
  command 'dfc' from deb dfc (3.1.1-1)
  command 'df' from deb coreutils (8.32-4.1ubuntu1)
See 'snap info <snapname>' for additional versions

Solution

as mentioned above run the command after mentioning the path:

sudo /home/osboxes/bin/dfx --version

To find the path run the command

echo "${PATH//:/$'\n'}"

---

To resolve all issues: I strongly recommends follow most voted ans. line of code.

because for me dfx new my_app was not working but it worked after I ran below line of codes.

1. test -e /home/navalega0109/bin/dfx && echo yay found it || echo oh no
2. "$HOME/bin/dfx" --version
3. echo "$PATH" | tr : "\n" | grep "$HOME/bin"

Answer 4

After installed on my local I got this message:

dfx-0.14.3-x86_64-linux.tar.gz: OK
Will install in: /home/akhisyabab/bin
info: Installed /home/akhisyabab/bin/dfx

in official documentation of IC, dfx should be located at /usr/local/bin/dfx, So I just link the location

sudo ln -s /home/akhisyabab/bin/dfx /usr/local/bin/dfx

It works for me. Thanks

Answer 5

when I used the command

dfx --version

it didn't recognoze.

but when I used the complete path it worked.

sudo /home/osboxes/bin/dfx --version

dfx 0.8.0

Answer 6

After installing DFX add your installed path on this line $ export PATH=$PATH:

Check that it has been added by running: echo "${PATH//:/$'\n'}"

Finally, restart Ubuntu again & run dfx --version it will definitely work and show you the current dfx version 0.11.0

Answer 7

you need to give it the path. run the code below and make sure to place the binary inside ~/bin instead of ~/bin/dfx

export PATH=$PATH:<REPLACE WITH YOUR INSTALLATION PATH>

you got your installation path at the bottom when you installed dfx where you find the ringt installion path

Answer 8

It will work once you restart Ubuntu

Answer 9

I got the same problem. For some reason there is a ~/bin directory so first I delete it then follow the previous answer:

ubuntu@ip-172-31-81-158:~$ PATH=~/bin:$PATH
ubuntu@ip-172-31-81-158:~$ export PATH
ubuntu@ip-172-31-81-158:~$ sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"
