ESLint couldn't determine the plugin "<%- pluginId %>" uniquely. <% for (const { filePath, importerName } of plugins) { %> - <%= filePath %> (loaded in "<%= importerName %>")<% } %> Please remove the "plugins" setting from either config or remove either plugin installation. If you still can't figure out the problem, please stop by https://gitter.im/eslint/eslint to chat with the team.
