Issue description

Recent versions of pipenv no longer work with pypy3.

Expected result

Expected pipenv to work.

Actual result

❯ PYENV_VERSION=pypy3.5-6.0.0 pyenv exec pipenv --verbose

ImportError: cannot import name 'pythonapi'

Steps to replicate

Simply install pipenv with PyPy3, then try to run any pipenv command.


pipenv --support won't work either.

PyPy doesn't support ctypes.pythonapi, but the root cause of the issue is that it shouldn't even try to import this module in the first place. I've investigated a bit and it looks with PyPy3, sys.stdout.encoding returns "utf8" instead of "utf-8". I'm unsure whether this is a PyPy bug or not, but since pipenv used to work fine with PyPy3 prior to (I think) #3096, can we relax the condition on this line to allow for "utf8" as well as "utf-8"?

Pipenv is not guaranteed to work on PyPy, nor is PyPy included in our CI setup.

Well, PyPy appears in setup.py classifiers? That should be removed, sorry for the trouble.

Hey @frostming, thanks for the reply. It's a bit disappointing to hear that PyPy isn't officially supported, as it means that packages that do support PyPy need to introduce additional complexity to use pipenv only on supported Python versions or not use pipenv at all.

Also, regarding the exact issue I described, I suspect this is a bug in pipenv:

  1. In __init__.py, sys.stdout and sys.stderr are replaced by io.TextIOWrappers with encoding set to 'utf8' (no dash):
    stdout_wrapper = io.TextIOWrapper(sys.stdout.buffer, encoding='utf8')
    atexit.register(stdout_wrapper.close)
    stderr_wrapper = io.TextIOWrapper(sys.stderr.buffer, encoding='utf8')
    atexit.register(stderr_wrapper.close)
    sys.stdout = stdout_wrapper
    sys.stderr = stderr_wrapper
  2. In _compat.py, the encoding is forced to UTF-8 by checking if sys.stdout/err.encoding.lower() is equal to 'utf-8' (with a dash):
    if stdout_encoding.lower() != "utf-8" or stderr_encoding.lower() != "utf-8":

I have no real qualms fixing PyPy support as it shouldn’t be hard...

I was caught off guard with this bug with Pypy3 too. This doesn't trigger any error with Cpython as it has a module ctype to import.

Glad to know this has been fixed !

Just noting that I just ran into this in Circle CI -- Since the #3322 PR hasn't landed in a release yet I'm going to attempt to use pipenv from master for the time being.

======================

Features & Improvements
-----------------------

-   `pipenv install` and `pipenv sync` will no longer attempt to install satisfied dependencies during installation. pypa#3057, pypa#3506
-   Added support for resolution of direct-url dependencies in `setup.py` files to respect `PEP-508` style URL dependencies. pypa#3148
-   Added full support for resolution of all dependency types including direct URLs, zip archives, tarballs, etc.
    -   Improved error handling and formatting.
    -   Introduced improved cross platform stream wrappers for better `stdout` and `stderr` consistency. pypa#3298
-   For consistency with other commands and the `--dev` option description, `pipenv lock --requirements --dev` now emits both default and development dependencies. The new `--dev-only` option requests the previous behaviour (e.g. to generate a `dev-requirements.txt` file). pypa#3316
-   Pipenv will now successfully recursively lock VCS sub-dependencies. pypa#3328
-   Added support for `--verbose` output to `pipenv run`. pypa#3348
-   Pipenv will now discover and resolve the intrinsic dependencies of **all** VCS dependencies, whether they are editable or not, to prevent resolution conflicts. pypa#3368
-   Added a new environment variable, `PIPENV_RESOLVE_VCS`, to toggle dependency resolution off for non-editable VCS, file, and URL based dependencies. pypa#3577
-   Added the ability for Windows users to enable emojis by setting `PIPENV_HIDE_EMOJIS=0`. pypa#3595
-   Allow overriding `PIPENV_INSTALL_TIMEOUT` environment variable (in seconds). pypa#3652
-   Allow overriding `PIP_EXISTS_ACTION` evironment variable (value is passed to pip install). Possible values here: <https://pip.pypa.io/en/stable/reference/pip/#exists-action-option> Useful when you need to `PIP\_EXISTS\_ACTION=i` (ignore existing packages) - great for CI environments, where you need really fast setup. pypa#3738
-   Pipenv will no longer forcibly override `PIP_NO_DEPS` on all vcs and file dependencies as resolution happens on these in a pre-lock step. pypa#3763
-   Improved verbose logging output during `pipenv lock` will now stream output to the console while maintaining a spinner. pypa#3810
-   Added support for automatic python installs via `asdf` and associated `PIPENV_DONT_USE_ASDF` environment variable. pypa#4018
-   Pyenv/asdf can now be used whether or not they are available on PATH. Setting `PYENV_ROOT`/`ASDF_DIR` in a `.env` file allows Pipenv to install an interpreter without any shell customizations, so long as pyenv/asdf is installed. pypa#4245
-   Added `--key` command line parameter for including personal PyUp.io API tokens when running `pipenv check`. pypa#4257

Behavior Changes
----------------

-   Make conservative checks of known exceptions when subprocess returns output, so user won\'t see the whole traceback - just the error. pypa#2553
-   Do not touch Pipfile early and rely on it so that one can do `pipenv sync` without a Pipfile. pypa#3386
-   Re-enable `--help` option for `pipenv run` command. pypa#3844
-   Make sure `pipenv lock -r --pypi-mirror {MIRROR_URL}` will respect the pypi-mirror in requirements output. pypa#4199

Bug Fixes
---------

-   Raise `PipenvUsageError` when \[\[source\]\] does not contain url field. pypa#2373
-   Fixed a bug which caused editable package resolution to sometimes fail with an unhelpful setuptools-related error message. pypa#2722
-   Fixed an issue which caused errors due to reliance on the system utilities `which` and `where` which may not always exist on some
    systems.
-   Fixed a bug which caused periodic failures in python discovery when executables named `python` were not present on the target `$PATH`. pypa#2783
-   Dependency resolution now writes hashes for local and remote files to the lockfile. pypa#3053
-   Fixed a bug which prevented `pipenv graph` from correctly showing all dependencies when running from within `pipenv shell`. pypa#3071
-   Fixed resolution of direct-url dependencies in `setup.py` files to respect `PEP-508` style URL dependencies. pypa#3148
-   Fixed a bug which caused failures in warning reporting when running pipenv inside a virtualenv under some circumstances.
-   Fixed a bug with package discovery when running `pipenv clean`. pypa#3298
-   Quote command arguments with carets (`^`) on Windows to work around unintended shell escapes. pypa#3307
-   Handle alternate names for UTF-8 encoding. pypa#3313
-   Abort pipenv before adding the non-exist package to Pipfile. pypa#3318
-   Don\'t normalize the package name user passes in. pypa#3324
-   Fix a bug where custom virtualenv can not be activated with pipenv shell pypa#3339
-   Fix a bug that `--site-packages` flag is not recognized. pypa#3351
-   Fix a bug where `pipenv --clear` is not working pypa#3353
-   Fix unhashable type error during `$ pipenv install --selective-upgrade` pypa#3384
-   Dependencies with direct `PEP508` compliant VCS URLs specified in their `install_requires` will now be successfully locked during the resolution process. pypa#3396
-   Fixed a keyerror which could occur when locking VCS dependencies in
    some cases. pypa#3404
-   Fixed a bug that `ValidationError` is thrown when some fields are missing in source section. pypa#3427
-   Updated the index names in lock file when source name in Pipfile is changed. pypa#3449
-   Fixed an issue which caused `pipenv install --help` to show duplicate entries for `--pre`. pypa#3479
-   Fix bug causing `[SSL: CERTIFICATE_VERIFY_FAILED]` when Pipfile `[[source]]` has `verify_ssl=false` and url with custom port. pypa#3502
-   Fix `sync --sequential` ignoring `pip install` errors and logs. pypa#3537
-   Fix the issue that lock file can\'t be created when `PIPENV_PIPFILE` is not under working directory. pypa#3584
-   Pipenv will no longer inadvertently set `editable=True` on all vcs dependencies. pypa#3647
-   The `--keep-outdated` argument to `pipenv install` and `pipenv lock` will now drop specifier constraints when encountering editable dependencies.
    -   In addition, `--keep-outdated` will retain specifiers that would otherwise be dropped from any entries that have not been updated. pypa#3656
-   Fixed a bug which sometimes caused pipenv to fail to respect the `--site-packages` flag when passed with `pipenv install`. pypa#3718
-   Normalize the package names to lowercase when comparing used and in-Pipfile packages. pypa#3745
-   `pipenv update --outdated` will now correctly handle comparisons between pre/post-releases and normal releases. pypa#3766
-   Fixed a `KeyError` which could occur when pinning outdated VCS dependencies via `pipenv lock --keep-outdated`. pypa#3768
-   Resolved an issue which caused resolution to fail when encountering poorly formatted `python_version` markers in `setup.py` and `setup.cfg` files. pypa#3786
-   Fix a bug that installation errors are displayed as a list. pypa#3794
-   Update `pythonfinder` to fix a problem that `python.exe` will be mistakenly chosen for virtualenv creation under WSL. pypa#3807
-   Fixed several bugs which could prevent editable VCS dependencies from being installed into target environments, even when reporting
    successful installation. pypa#3809
-   `pipenv check --system` should find the correct Python interpreter when `python` does not exist on the system. pypa#3819
-   Resolve the symlinks when the path is absolute. pypa#3842
-   Pass `--pre` and `--clear` options to `pipenv update --outdated`. pypa#3879
-   Fixed a bug which prevented resolution of direct URL dependencies which have PEP508 style direct url VCS sub-dependencies with
    subdirectories. pypa#3976
-   Honor `PIPENV_SPINNER` environment variable pypa#4045
-   Fixed an issue with `pipenv check` failing due to an invalid API key from `pyup.io`. pypa#4188
-   Fixed a bug which caused versions from VCS dependencies to be included in `Pipfile.lock` inadvertently. pypa#4217
-   Fixed a bug which caused pipenv to search non-existent virtual environments for `pip` when installing using `--system`. pypa#4220
-   `Requires-Python` values specifying constraint versions of python starting from `1.x` will now be parsed successfully. pypa#4226
-   Fix a bug of `pipenv update --outdated` that can\'t print output correctly. pypa#4229
-   Fixed a bug which caused pipenv to prefer source distributions over wheels from `PyPI` during the dependency resolution phase. Fixed an issue which prevented proper build isolation using `pep517` based builders during dependency resolution. pypa#4231
-   Don\'t fallback to system Python when no matching Python version is found. pypa#4232
