安裝 php-xml 和 php-xml7.0 后在 Ubuntu 14.04 上出現 Pear 錯誤“未找到 XML 擴展”

Question

我想在 Ubuntu 14.04 上使用 pecl 命令將 redis 安裝到我的 php 中。 但是我的 Pear 給了我一個警告列表：

XML Extension not found

最后一行給了我這個信息

未找到 XML 擴展

，雖然我安裝了#sudo apt-get install php-xml php7.0-xml 。 但同樣的問題仍然存在。

可能是什么問題呢？

Answer 1

安裝此列表，一切都會正常工作:)

sudo apt-get install php-pear pkg-config libbson-1.0 libmongoc-1.0-0 php-xml php7.0-xml php-dev

Answer 2

在某些安裝中，pecl 中存在錯誤。 找到這條線；

exec $PHP -C -n -q $INCARG -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv="On" $INCDIR/peclcmd.php "$@" 

刪除 -n

如果要編寫腳本，請嘗試：

sed -i "$ s|\-n||g" /usr/bin/pecl

Answer 3

面對這個問題，我只需要安裝 php-xml

sudo apt-get install php-xml

為什么可以在這里找到完整的解釋

Answer 4

注意：這並不完全是對原始問題的回答，但這可能在現在和將來更相關。

在更現代的 Ubuntu 版本（如 20.04）中出現此類錯誤的可能原因之一是系統中可能安裝了多個版本的 PHP。

即使您只安裝 7.x 版本，以及 7.x 插件和 f.ex。 一些像 Apache 這樣的 HTTP 服務器並不意味着不會安裝另一個 PHP。 它可能最初安裝（例如在 docker 基礎映像中）或作為其他東西的依賴項。

我在以前用於構建和工作的舊 docker 容器中遇到過這樣的問題。

解決方案是在安裝 PEAR 之前刪除 PHP 8.x。

sudo apt-get purge -y `apt list --installed | cut -d/ -f1 | grep php8 | awk '{print $1}' |tr "\n" " "`

或者

sudo apt-get purge -y `dpkg -l | grep php8 | awk '{print $2}' |tr "\n" " "`
