我嘗試在新創(chuàng)建的 Amazon EC2 實例上安裝 php-dom 擴(kuò)展，但沒有成功，但無論我嘗試什么，都失敗了...我嘗試了以下命令（以及其他命令）：sudo yum install php-domsudo yum install php-xml這是我每次得到的：Loaded plugins: extras_suggestions, langpacks, priorities, update-motdamzn2-core                                               | 3.7 kB     00:00     202 packages excluded due to repository priority protectionsResolving Dependencies--> Running transaction check---> Package php-xml.x86_64 0:5.4.16-46.amzn2.0.2 will be installed--> Processing Dependency: php-common(x86-64) = 5.4.16-46.amzn2.0.2 for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Processing Dependency: libxslt.so.1(LIBXML2_1.0.24)(64bit) for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Processing Dependency: libxslt.so.1(LIBXML2_1.0.22)(64bit) for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Processing Dependency: libxslt.so.1(LIBXML2_1.0.18)(64bit) for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Processing Dependency: libxslt.so.1(LIBXML2_1.0.13)(64bit) for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Processing Dependency: libxslt.so.1(LIBXML2_1.0.11)(64bit) for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Processing Dependency: libxslt.so.1()(64bit) for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Processing Dependency: libexslt.so.0()(64bit) for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Running transaction check---> Package libxslt.x86_64 0:1.1.28-5.amzn2.0.2 will be installed---> Package php-xml.x86_64 0:5.4.16-46.amzn2.0.2 will be installed--> Processing Dependency: php-common(x86-64) = 5.4.16-46.amzn2.0.2 for package: php-xml-5.4.16-46.amzn2.0.2.x86_64--> Finished Dependency Resolution據(jù)我了解，php-xml（包括php-dom）需要包php-common版本5.4.16（？！），但我正在運(yùn)行PHP版本7.3，這可能是沖突的原因？我對 AWS 相當(dāng)陌生，甚至對終端命令還很陌生，因此非常感謝這里的任何幫助！如果您需要有關(guān)服務(wù)器的更多信息，我很樂意提供給您，我只是不知道此時什么可能有用......謝謝。
