Hi, I’ve tried to install Pants on my MacBook Pro (OSX 10.14.6). First try: 
pipx install pants
-> failed, with some hints that this was not the right 
pants
package. Second try: 
pipx install pantsbuild.pants
-> failed, with the following error:

Is there a way to fix this installation problem ? Also, I’d like to know if installing pants globally (using 
pip
or 
pipx
) will be supported ? (I’d rather type 
pants ...
than 
./pants ...
).
h
Hey Stefane, welcome! Installing pants globally is not yet supported. The recommended installation is to use the script at https://www.pantsbuild.org/docs/installation, which will handle things like upgrading Pants whenever you change your pants.toml and ensure everyone on your team is using the same version Sorry about that, I hear you with wanting to type pants instead of ./pants
p
You can create an alias in 
~/.zprofile
or 
~/.zshrc
(or 
~/.bashrc
if you’re using bash instead of the zsh default on Mac):
Copy code
alias pants='./pants'

Thanks for the tips.
But the documented method doesn’t work for me:

Hm, could you please add 
set -x
to the top of the bash script and copy the output into here? I'm suspecting it's trying to use an incorrect Python version perhaps
To be crystal clear, you recently downloaded the script? That is, it's not a stale version from months/years ago?

Thank you @witty-house-77262, that's really helpful. This confirms it's trying to use Python 3.9, which is good and what we'd expect Something that looks a little fishy to me is 
CPython3.9.6.final.0-64
. It looks like you're using 
pyenv
, could you please run 
pyenv global
? Another option is to try running Pants w/ another Python interpreter by setting the env var 
PYTHON=python3.8
for example. Even if that's not going to be the permanent solution, it could help to debug
w
Yes I was using pyenv’s 3.9.6.
Same issue using Python 3.9.6 from homebrew.

Using 
PYTHON=python3.8
I get a different error:

Ah ha, I see now. The issue is using an older version of macOS. We used to use Travis to build our wheels on macOS 10.11 El Capitan. But, Travis jacked up their CI prices and it was burning through Pants Build's budget. So we migrated to GitHub Actions, which unfortunately only offers macOS 10.15 Catalina and newer for workers. So we made a difficult decision to drop support for anything earlier than 10.15 in Pants 2.5+ (https://groups.google.com/u/1/g/pants-devel/c/Bfk4e_9JiT4/m/bTkVzcBfAwAJ for announcement) Apparently we did not document that in Pants's docs, totally our bad there! So your options are unfortunately: • try Pants 2.4.2 • use a devbox / Linux • upgrade to macOS 10.15 or newer
(fyi this is because Pants includes a Rust native binary for its engine, which gives its performance and parallelism. It's native code, so less portable than some Python projects)

Thanks, it makes sense.
(BTW: coincidentally, I stopped using Travis this week after being a user for the last 10 years and a customer for the last 5 years).
Isn’t there a way to trigger a Rust build on the user’s machine when a wheel is not available? (I have 
rustc
installed).

Yeah, we have a ticket to distribute an sdist: https://github.com/pantsbuild/pants/issues/10718. But we've punted in part because what we really want to start doing is distributing Pants as a binary, rather than going through these PyPI gymnastics In the meantime, this is how you can create for your current platform: https://www.pantsbuild.org/docs/installation#building-pants-from-sources
FYI, macOS Catalina requirement now documented: https://www.pantsbuild.org/docs/installation#prerequisites Thanks for sticking through debugging this! Hopefully you'll be the last to be tripped up by it 🤞

Hi @witty-house-77262 just wanted to follow up and see if this is still an issue?
