Regression 2018-11-14 when using --pre flag with particular Pipfile syntax | TypeError: list indices must be integers or slices, not tuple

See original GitHub issue

Issue description

I started getting the following error when attempting to use pipenv versions 2018-11-14 (still exists in 2018-11-26) when installing with the --pre flag: pipenv install --pre.

Expected result

Pipenv installs packages.

Actual result

Pipenv fails with TypeError (this is with the --verbose flag)

The root cause:

packages section is splitted in several places, in this case, appending a new table(pipenv section) will throw an error.

The workaround is to combine the packages section in one place, and I pushed a PR to the upstream https://github.com/sdispater/tomlkit/pull/34 to fix this.

@techalchemy The fix has been in tomlkit’s master but not released yet. Since this issue is corner case and has a workaround available, i’ll update the vendor after the upstream is released.

BTW This toml is allowed by spec
