TYPO3 CMS 8.7.27:在null上调用成员函数getPackagePath()

Question

在typo3 CMS 8.7.27中安装扩展后，我得到以下错误..似乎ExtensionManagementUtility无法加载ah_contentapi。

​

​

这是我的根目录下的composer.json文件(/var/www/html/typo3)，用于加载我的扩展名：

我已在以下位置清除安装工具中的缓存: 1. -> important actions -> clear all cache 2. -> Clean -> clean typo3temp/ folder

来自composer.lock的文章：

Answer 1

当typo3conf/ext/<folder_name>下的扩展文件夹名称与系统某些地方使用的扩展密钥不匹配时(例如，在TypoScript中使用EXT:your_extension_key/...语法)，就会出现此错误。

更改文件夹名称为我修复了类似的问题。

Answer 2

检查PHP版本并尝试将其从7.4更改为7.3。

我曾经在一个应该与PHP 7.4兼容的扩展中遇到过这个问题，但在现实生活中却并非如此。这为我解决了这个问题。

这里的问题是：

• 您是如何更新到8.7.27的(执行了哪个composer命令)
• 您的composer.lock是什么样子的？
• 您是否使用TYPO3控制台或任何其他特殊的composer插件/命令行界面命令，例如生成composer
