#17721 Support `./pants freeze --resolve=xyz` New issue created by da-tubi Is your feature request related to a problem? Please describe. import a lockfile into an existing virtualenv Describe the solution you'd like

./pants freeze --resolve=xyz.                      # like pip freeze
./pants freeze --resolve=xyz --secured     # like pex3 lock export

or

./pants import --resolve=xyz # in that way, we do not need to pip install

Describe alternatives you've considered Workaround 1 https://github.com/da-tubi/pants-minimal-freeze Workaround 2 The following command line is similar to

pip freeze

pex3 lock export 3rdparty/python/xxx.lock

Then we can use the exported

requirements.txt

in the specific virtual env:

pex3 lock export 3rdparty/python/xxx.lock > /tmp/requirements.txt
# pyenv activate xxx or conda activate xxx
pip install -r /tmp/requirements.txt

And

pex3 lock export

does not work for pants' lockfile, because there are

//

leading parts. For now, we can use command line to strip the leading
