UnexpectedValueException: Expecting a version number in the format x.y #10084
Description
Steps to reproduce
- Set
phpVersionto"5.1"in the configuration file. - Run Psalm.
Actual result
Uncaught UnexpectedValueException: Expecting a version number in the format x.y in /opt/psalm/vendor/vimeo/psalm/src/Psalm/Internal/Analyzer/ProjectAnalyzer.php:1174
Stack trace:
#0 /opt/psalm/vendor/vimeo/psalm/src/Psalm/Internal/CliUtils.php(500): Psalm\Internal\Analyzer\ProjectAnalyzer->setPhpVersion('5.1', 'config')
#1 /opt/psalm/vendor/vimeo/psalm/src/Psalm/Internal/Cli/Psalm.php(349): Psalm\Internal\CliUtils::initPhpVersion(Array, Object(Psalm\Config), Object(Psalm\Internal\Analyzer\ProjectAnalyzer))
#2 /opt/psalm/vendor/vimeo/psalm/psalm(9): Psalm\Internal\Cli\Psalm::run(Array)

#4 {main}
(Psalm 5.11.0@c9b192ab8400fdaf04b2b13d110575adc879aa90 crashed due to an uncaught Throwable)
Expected result
- No uncaught exception, no stack trace.
- Correct error message telling that PHP 5.1 specified in the configuration file ".xml" is not supported by Psalm, and only PHP 5.4-5.6, 7.0-7.4, 8.0-8.2 are supported.
Root cause
psalm/src/Psalm/Internal/Analyzer/ProjectAnalyzer.php
Lines 1182 to 1184 in dc81630
Additional information
The error message is also wrong because actually version numbers in the formats x.y.z (e.g. "8.2.8") are also expected.
