FileNotFoundError: [Errno 2] No such file or directory: 'pip3'

FileNotFoundError: [Errno 2] No such file or directory: 'pip3'

occurs when installing from the repo, as per instruction for Ubuntu from the main GitHub page (added repo, updated, then the installation command like below). As result howdy is not installed as a command (which howdy returns nothing).

After detection, Howdy knows how certain it is that the match is correct.
How certain Howdy needs to be before authenticating you can be customized.

F: Fast.
Allows more fuzzy matches, but speeds up the scanning process greatly.

B: Balanced.
Still relatively quick detection, but might not log you in when further away.

S: Secure.
The safest option, but will take much longer to authenticate you.

You can always change this setting in the config.

I've searched for similar issues already, and my issue has not been reported yet. :)

Linux distribution (if applicable): Ubuntu 21.04

Howdy version (sudo howdy version): 2.6.1

[Banjalucan]

I have the same problem (Ubuntu 21.10)

[boltgolt]

Please install pip3: sudo apt install python3-pip

[Banjalucan]

sudo apt install python3-pip

Thanks for the help. Unfortunately, this did not work because pip3 was already installed and I received the following message: python3-pip is already the newest version (20.3.4-4).

I also tried sudo apt reinstall python3-pip, but this didn't help either.

Any other suggestions?

[jergao]

Same problem here. (Kubuntu 21.10)

[boltgolt]

What does which pip3 give you?

[jergao]

/usr/local/bin/pip3

[boltgolt]

One fix would be to open the .deb with the archive manager and replacing pip3 with /usr/local/bin/pip3 in the postinst file. I guess. Not sure what's going on here

[expl0r3rgu1]

Same issue on Pop OS

I also got this on Ubuntu 21.10 the second time I installed it. Worked first time, but when I uninstalled it and installed it again it failed.

[yingmanwumen]

same in Debian 5.10

[Onion2222]

I also got this on Ubuntu 21.10 the second time I installed it. Worked first time, but when I uninstalled it and installed it again it failed.

Same problem, solved by doing: sudo apt remove --purge howdy sudo apt install --reinstall python3-pip sudo apt install howdy It works now after a complete re-installation of howdy, I don't know what was wrong... Maybe the path to pip3 but I'm not sure and didn't check...

[MrConorAE]

I think I might know what's going on: immediately before the install crashes, pip says

WARNING: The scripts pip, pip3 and pip3.9 are installed in /usr/local/bin which is not on PATH. 

Maybe it can't find pip3 because it's, as pip says, not on the PATH by default?

[MrConorAE]

Added /usr/local/bin to PATH, no effect. :/

Also, for me, which pip3 returns /usr/local/bin//pip3. Is that double slash causing side effects? If I reinstall pip, it changes back to /usr/bin - this only happens after Howdy force-installs pip again (during the "upgrading pip to the latest version" step)

[vslm698-p]

Another away to fix the problem, sudo ln -sv $(which pip3) /usr/bin/pip3

[jcatama]

@vslm698-p thanks man, this works for me: sudo ln -sv $(which pip3) /usr/bin/pip3

[liqi001]

sudo pip3 list Here, it is an error caused by my insufficient permission. pip3 install --upgrade pip

[egberts]

same issue on Debian 11

[upst-io]

sudo pip3 list Here, it is an error caused by my insufficient permission. pip3 install --upgrade pip This worked for me on Debian 11 ( Bullseye )

[alexanderLinear]

In a particular environment i only have user rights - so i am using the "--user" install option within pip. But even then such an install will still fail for me with that message (along with some calls stacks):

FileNotFoundError: [Errno 2] No such file or directory: '/usr/bin/pip3.8'

If that binary is not there, then its not there and the tooling should not fault but only warn about that - at least my best case of understanding for the moment.

But there is an interesting side note:

WARNING: The scripts pip, pip3, pip3.11 and pip3.8 are installed in '/home/<username>/.local/bin' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

I will give that warning some attention now and try out some path addition...
