Chưa có ai nhận issue này.

## Details

* **Python version**: Python 3.5.3 (a39af0be3a22, Jun 05 2017, 20:18:00); [PyPy 5.8.0-beta0 with GCC 6.2.0 20160901]
* **Platform**: Ubuntu 18.04.1 LTS
* **Do you use pgbouncer?**: N/A, failed to install
* **Did you install asyncpg with pip?**: Tried to
* **If you built asyncpg locally, which version of Cython did you use?**: Installed from pypi
* **Can the issue be reproduced under both asyncio and
[uvloop](https://github.com/magicstack/uvloop)?**: N/A, failed to install

Tái hiện lỗi với virtualenv PyPy được hiển thị và `pip install asyncpg`, sau đó kiểm tra `asyncpg/protocol/record/recordobj.c` cùng với các header Python của PyPy được tham chiếu trong build log. Được coi là hoàn thành khi gói asyncpg được build và cài đặt thành công trong môi trường PyPy đã báo cáo.
