Question

Maybe related to the above question from Sean re urllib I m getting this error ```ImportError urllib3 v2 0 only supports OpenSSL 1 1 1+ currently the ssl module is compiled with LibreSSL 2 8 3 See <https github com urllib3 urllib3 issues 2168>``` I was not previously getting this error it started yesterday Sean said May 4 for them I ve tried recreating my previous setup using the steps below FYI our pants version is 2 13 0 Steps 1 Made a fresh clone of our repo 2 Made a fresh branch from an earlier commit hash April 25 3 Made a fresh virtual env I don t think this matters for Pants but did it anyway 4 Cleaned out the `~ cache pants` dir on my local system 5 Ran ` pants version` which fails with the above ImportError What am I missing I can only think of 2 reasons this could happen 1 Some permanent change to my system was made that s somehow influencing Pants though I don t believe it should since it s hermetic execution 2 During Pants bootstrapping live resources are pulled independent of local configuration or there s a config setting that could fix this but I do not yet know of it I m new to Pants so thank you for your help and patience

Unfortunately this is a problem with installing bootstrapping pants itself which isn t fully hermetic reproducible As in doing a fresh install of pants on May 1 might have different behaviour to May 9 In theory the `PIP CONSTRAINTS` suggestion in <https pantsbuild slack com archives C046T6T9U p1683661374866099 thread ts=1683574114 661669 amp cid=C046T6T9U> should help with this installation issue

You may need do step 4 again before doing that to ensure you get a fresh install

Unfortunately this doesn t seem to work running ` pants` blanket fails with that ImportError I downloaded an updated ` pants` script that sources ` pants bootstrap` and added the constraints I confirmed that it s detecting the file though I m not sure how to confirm whether it s correctly passing those constraints to pip any guidance I can see in `~ cache pants 2 13 0 py39 lib python3 9 site packages ` that the urllib3 version is 2 0 2 despite setting urllib3 lt 2 in constraints

As a side note I tried installing the pants binary launcher and this issue goes away so I guess my local python interpreter somehow got corrupt and is passing that on to the ` pants` installer

gt guess my local python interpreter somehow got corrupt and is passing that on Both `pants` and ` pants` create a venv as a 1st step It s just that `pants` uses a hermetic interpreter and ` pants`picks one from your system but either way its a fresh new venv They each then install `pantsbuild pants` in the fresh venv using `pip install ` and thus the `PIP ` env var trick works

< best furniture 15331> in my example CLI session above I did not use ` pants bootstrap` for clarity Perhaps you can do that too to rule out weirdness there 1st

One way to test PIP CONSTRAINT is use a bogus value then Pip blows up ```jsirois Gill Windows ~ dev pantsbuild example django main $ rm rf ~ cache pants setup jsirois Gill Windows ~ dev pantsbuild example django main $ PIP CONSTRAINT=spam txt pants V Bootstrapping Pants using home jsirois pyenv shims python3 9 Creating the virtualenv PEX Downloading the Pex PEX SHA256 fingerprint of <https github com pantsbuild pex releases download v2 1 103 pex> verified Installing pantsbuild pants==2 14 0 into a virtual environment at home jsirois cache pants setup bootstrap Linux x86 64 2 14 0 py39 ERROR Could not open requirements file Errno 2 No such file or directory spam txt WARNING You are using pip version 21 1 2 however version 23 1 2 is available You should consider upgrading via the home jsirois cache pants setup bootstrap Linux x86 64 pants F188cA install bin python m pip install upgrade pip command ```

I just tested it by setting the env var inline instead of through pants bootstrap and it works I went back and added `export` to my ` pants bootstrap` file so that must ve been the problem

best-furniture-15331 · Answer

I originally had only `PIP CONSTRAINT=constraints txt` without export

enough-analyst-54434 · Answer

ah yes the export is needed
