asyncpg has no external dependencies when not using GSSAPI/SSPI authentication. The recommended way to install it is to use pip:
If you need GSSAPI/SSPI authentication, the recommended way is to use
$ pip install 'asyncpg[gssauth]'
This installs SSPI support on Windows and GSSAPI support on non-Windows platforms. SSPI and GSSAPI interoperate as clients and servers: an SSPI client can authenticate to a GSSAPI server and vice versa.
On Linux installing GSSAPI requires a working C compiler and Kerberos 5 development files. The latter can be obtained by installing libkrb5-dev package on Debian/Ubuntu or krb5-devel on RHEL/Fedora. (This is needed because PyPI does not have Linux wheels for gssapi. See here for the details.)
It is also possible to use GSSAPI on Windows:
Building from source
pip install gssapi
Install Kerberos for Windows.
Set the
gsslibparameter or thePGGSSLIBenvironment variable to gssapi when connecting.
If you want to build asyncpg from a Git checkout you will need:
To have cloned the repo with –recurse-submodules.
A working C compiler.
CPython header files. These can usually be obtained by installing the relevant Python development package: python3-dev on Debian/Ubuntu, python3-devel on RHEL/Fedora.
Once the above requirements are satisfied, run the following command in the root of the source checkout:
A debug build containing more runtime checks can be created by setting the ASYNCPG_DEBUG environment variable when building:
$ env ASYNCPG_DEBUG=1 pip install -e .Running tests
If you want to run tests you must have PostgreSQL installed.
To execute the testsuite run:
