回答1:

In TYPO3 8 LTS getPageRenderer() Methods Deprecated. Now, You can use PageRender Methods like below.

$pageRender = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Core\Page\PageRenderer::class);
$pageRender->addJsFooterFile($jsFile, 'text/javascript', true, false, '', true);

回答2:

The extension ke_search is not compatible with TYPO3 8LTS yet. You can check the compatibility at the TER.

The exception is thrown because the extension still calls a method that was first deprecated in TYPO3 7LTS (see deprecation RST) and finally removed in TYPO3 8LTS (see breaking RST).
