Question

我最近将Symfony从2.1更新到2.2，现在我收到了错误：

错误：在vendor / symfony / symfony / src / Symfony / Bundle / SecurityBundle / Twig / Extension / LogoutUrlExtension.php第41行中找不到类'Twig_SimpleFunction'

我的composer.json：

...
"require": {
    "php": ">=5.4",
    "symfony/symfony": "2.2.*",
    "twig/twig": "1.11.x",
    "twig/extensions": "1.0.x-dev",
    "noetix/easy-csv": "dev-master",
    "symfony/assetic-bundle": "2.*",
    "symfony/swiftmailer-bundle": "2.*",

    "white-october/pagerfanta-bundle": "dev-master",
    "knplabs/knp-menu-bundle": "dev-master",
    "knplabs/knp-menu": "2.0.x-dev",
    "exercise/elastica-bundle": "dev-master",
    "gregwar/captcha-bundle": "dev-master",
    "nelmio/api-doc-bundle": "2.1.*",
    "fr3d/ldap-bundle": "2.0.*@dev",
    "conjecto/easyrdf-bundle": "dev-master"
},
...

Twig deprecated features page说：“从Twig 1.x开始，使用Twig_SimpleFunction”。我有1.11，所以我不明白我做错了。

找到它。我怀疑问题在于无效的依赖关系。我下载了Symfony2.2.11并相应地更改了我的composer.json（注意不再引用twig，并更改了一些symfony / *和sensio / *依赖项）：

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.2.*",
    "twig/extensions": "1.0.*",
    "noetix/easy-csv": "dev-master",
    "symfony/assetic-bundle": "2.1.*",
    "symfony/swiftmailer-bundle": "2.2.*",
    "symfony/monolog-bundle": "2.2.*",
    "sensio/distribution-bundle": "2.2.*",
    "sensio/framework-extra-bundle": "2.2.*",
    "sensio/generator-bundle": "2.2.*",
    "jms/security-extra-bundle": "1.4.*",
    "jms/di-extra-bundle": "1.3.*",
    "jms/serializer": "0.12.*",
    "jms/serializer-bundle" : "0.12.*@dev",
    "jms/metadata" : "1.3.*",
    "friendsofsymfony/user-bundle": "patch-1-dev",
    "friendsofsymfony/jsrouting-bundle": "1.2.*",
    "propel/propel1": ">=1.6.7",
    "propel/propel-bundle": "1.2.x-dev",
    "willdurand/propel-typehintable-behavior": "dev-master",
    "pagerfanta/pagerfanta": "1.0.x-dev",
    "white-october/pagerfanta-bundle": "dev-master",
    "knplabs/knp-menu-bundle": "dev-master",
    "knplabs/knp-menu": "2.0.x-dev",
    "exercise/elastica-bundle": "dev-master",
    "gregwar/captcha-bundle": "dev-master",
    "nelmio/api-doc-bundle": "2.1.*",
    "fr3d/ldap-bundle": "2.0.*@dev",
    "conjecto/easyrdf-bundle": "dev-master"
},

这个安装了枝条1.15，一切正常。 The manual page有错误 - Twig_SimpleFunction出现在＆gt; 1.11和＆lt; = 1.15之间，而不是1.x。

Twig扩展类未命名空间。你有没有检查过你没有改变它？

在您的扩展程序类中，您应该使用\Twig_SimpleFunction，而不仅仅是Twig_SimpleFunction

升级到Symfony 2.2后出现“Class'Twig_SimpleFunction'错误”
