Installation Issues

Here we capture issues that people have had when installing and running PSyclone in case it helps others.

Config file not found

If you get a message like the following when running the psyclone script: PSyclone configuration error: psyclone.cfg not found in any of ['/home/rupert/proj/PSyclone/examples/lfric/eg3/.psyclone', '/home/rupert/.local/share/psyclone', '/usr/share/psyclone'] then you have probably installed PSyclone in a non-standard location or used a live install (using pip -e ...). If so the psyclone.cfg configuration file will not be found in the standard Python paths. To solve this you first need to find the file. For a non-standard installation location the file will be in the installation location under share/psyclone. For a live install the file will be in the config directory in the local PSyclone source code. Once you have found the file, the simplest solution is to set the PSYCLONE_CONFIG environment variable to point to this file e.g. export PSYCLONE_CONFIG=/home/userx/psyclone/config/psyclone.cfg.

Installing on a MAC

• If both Python 2 and 3 are installed then you might need to explicitly call the correct version of pip. The particular problem was that pip install defaulted to Python 2 whereas the default Python environment was Python 3. Using pip3 resolved the issue.

• Depending on the system setup, a local install of PSyclone using pip might not add example and tutorial directories. if this is an issue, a workaround is to use python setup.py install instead. This is captured in issue #861.
