Q14 ` pants export` seems not to have any options <https www pantsbuild org docs reference export|https www pantsbuild org docs reference export> What does it do exactly Could I use to generate a unified venv that includes all targets for example When I run it `ExportError Failed to write virtualenv for the resolve None using CPython==3 10 to dist export python virtualenv` So my codes use Python 3 10 but pants is running with the apt installed system Python 3 8 Can I change it as well I ve explicitly set pants toml already

Ok I should look <https www pantsbuild org docs setting up an ide> hmmm

rhythmic-morning-87313 · Answer

ah i should configure the resolve first to get it working

rhythmic-morning-87313 · Answer

the doc says strongly recommended but it seems that if i don t configure it it does not work

rhythmic-morning-87313 · Answer

ok setting it removes None from the error message

rhythmic-morning-87313 · Answer

but still I m getting another error

rhythmic-morning-87313 · Answer

etcetra is a package that requires Python 3 9 or higher and the target venv is using Python 3 10 so I believe it should be fine

hmm I ve regenerated the user lockfile after gathering all external dependencies to the unified requirements and running ` pants export ` gives me ```Failed to digest inputs Error storing Digest hash Fingerprint lt 7ab31018a93d8802afa8cd123018cd5dfb3260da0678ad66acd9178a598fe02e gt size bytes 65795373 Input output error ```

rhythmic-morning-87313 · Answer

it still gives errors like this

rhythmic-morning-87313 · Answer

The size of `~ cache pants` is about 2 GiB

rhythmic-morning-87313 · Answer

hmmm this issue may be related to <https github com pantsbuild pex issues 1020>

rhythmic-morning-87313 · Answer

I think if I could rebuild my local pants source checkout using pyenv provided Python 3 10 instead of apt installed Python 3 8 I could workaround it

rhythmic-morning-87313 · Answer

ok

rhythmic-morning-87313 · Answer

`PY=$ pyenv prefix 3 10 4 bin python pants local export ` resolves the issue

rhythmic-morning-87313 · Answer

it creates a unified venv that has all dependencies but it seems not be installing editable versions of the first party packages

rhythmic-morning-87313 · Answer

hmm

rhythmic-morning-87313 · Answer

ok although additionally installed editable pkgs in the exported venv need to be reinstalled whenever running `export` but anyway I think we could make the plugin workflow
