使用 mjml-theme-converter for Prestashop 时出现“无法转换 mjml 文件”错误

如何解决使用 mjml-theme-converter for Prestashop 时出现“无法转换 mjml 文件”错误

我正在使用 Mjml 和 Twig 为 Prestashop 开发电子邮件模板主题，现在我需要将 mjml.twig 模板转换为 html .twig 模板：

welcome.mjml.twig --------welcome.html.twig
account.mjml.twig --------- account.html.twig
order_conf.mjml.twig ----- order_conf.html.twig
template.mjml.twig--------- template.html.twig

为此，Prestashop 团队创建了一个完全可以执行此操作的工具 (https://github.com/PrestaShop/mjml-theme-converter)，但是一旦我运行以下命令，我就会收到“无法转换 mjml 文件”错误:

$ ./bin/console prestashop:mail:convert-mjml simple_mjml ./simple_mjml

错误位于 MjmlConverter.PHP（第 122 行），一旦被追踪，它似乎来自 Symfony TemplateNameParser.PHP（第 75 行）
