Hi, is it possible to override the default 
pex
version. I am on pants 
2.11.1rc2
which has pinned its pex version to 2.1.90. I am trying to use pex v2.1.93 by adding it to 
pants.toml
Copy code
[pex-cli]
version = "v2.1.93"
But I get this error when trying to update the lockfiles
Copy code
pants generate-lockfiles
12:01:59.08 [ERROR] 1 Exception encountered:

  UnknownVersion: No known version of pex v2.1.93 for macos_x86_64 found in ('v2.1.90|macos_arm64|2781255baf77c2a8fdc85c5e830f7191a6048fd91d2e20b5c7a20e5a0b7beb66|3755345', 'v2.1.90|macos_x86_64|2781255baf77c2a8fdc85c5e830f7191a6048fd91d2e20b5c7a20e5a0b7beb66|3755345', 'v2.1.90|linux_x86_64|2781255baf77c2a8fdc85c5e830f7191a6048fd91d2e20b5c7a20e5a0b7beb66|3755345')

Here is the doc link https://www.pantsbuild.org/docs/reference-pex-cli I think it fails because of 
known_versions
which is checking for 2.1.90.
c
Yes, you need to override the known versions as well.
r
@curved-television-6568 Do you know what's the purpose of 
use_unsupported_version
? I thought setting it to warning would allow me to avoid overriding 
known_versions
But it still throws an error
c
Yeah (backstory https://github.com/pantsbuild/pants/pull/12332 ) There’s a constraint in Pants for which version of pex to use. If you go outside this constraint, we want to flag that things may break. So it is only for making sure that you know what you do, and if things break, there would be the first place to look. So you still need to provide known versions to actually use another version of pex.
r
ah ok! I tried to generate the known version format but the size I calculate using 
wc -c
on macos doesn't match what pants is calculating

c
oh..

Copy code
known_versions = [
  "v2.1.93|macos_arm64|e20143efdab8591a271def3f35909036c313968a267e57c94f582b911bbaf315|2732075",
  "v2.1.93|macos_x86_64|e20143efdab8591a271def3f35909036c313968a267e57c94f582b911bbaf315|2732075",
  "v2.1.93|linux_x86_64|e20143efdab8591a271def3f35909036c313968a267e57c94f582b911bbaf315|2732075"
]

try with 
80fc6b94f5db253a71061974cb8d8ce520932aef44d989e9057917cc33a30fd6
and

I am running 
wc -c
on downloaded wheel
Copy code
wc -c pex-2.1.93-py2.py3-none-any.whl
 2732075 pex-2.1.93-py2.py3-none-any.whl
Seems to be working. So what/how you generated that?
c
you must use the same url as the url template https://github.com/pantsbuild/pex/releases/download/{version}/pex
Copy code
--pex-cli-url-template=<str>
  PANTS_PEX_CLI_URL_TEMPLATE
  url_template
      default: <https://github.com/pantsbuild/pex/releases/download/{version}/pex>
      current value: <https://github.com/pantsbuild/pex/releases/download/{version}/pex>
      URL to download the tool, either as a single binary file or a compressed file (e.g. zip file). You can change this to point to your own hosted file, e.g. to work with proxies or for access via the filesystem through a
      `file:$abspath` URL (e.g. `file:/this/is/absolute`, possibly by [templating the buildroot in a config file](<https://www.pantsbuild.org/v2.13/docs/options#config-file-entries))>.
      
      Use `{version}` to have the value from --version substituted, and `{platform}` to have a value from --url-platform-mapping substituted in, depending on the current platform. For example,
      <https://github.com/.../protoc-{version}-{platform}.zip>.

I used
Copy code
$ curl -s -L <https://github.com/pantsbuild/pex/releases/download/v2.1.93/pex> | tee >(wc -c) >(shasum -a 256) >/dev/null
