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)"

Command 'dfx' not found, did you mean:

See 'snap info <snapname>' for additional versions.

adel@adel-VirtualBox:~$ cd /bin
adel@adel-VirtualBox:/bin$ cd dfx
bash: cd: dfx: No such file or directory

Below is my Ubuntu version:

adel@adel-VirtualBox:~$ lsb_release -a

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

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

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

Max, like I mentioned in my post; nothing gets created, I should have been more detailed. I updated my post to clarify that directory `dfx` is not created; I also added the terminal output to show that. – Adel Rustum Oct 08 '20 at 14:29

I misunderstood the script logic and thought it will place the binary inside `~/bin/dfx` instead of `~/bin`. Now it all makes sense and works fine. – Adel Rustum Oct 08 '20 at 21:41

but when I used the complete path it worked.

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

dfx 0.8.0

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)"

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

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

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.

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

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
