Issue

Configuring a certificate for a private repo via the below doesn't work:

poetry config certificates.my-private-pypi.cert /Users/xxx/yyy_ca.pem

However pointing to the pem file via "export REQUESTS_CA_BUNDLE" will make it work. If it matters the below configs are also set:

virtualenvs.create = true
virtualenvs.in-project = true
