我得到一个错误安装Xdebug在Alpine docker.我做错了什么?

Question

我试图在Alpine 3.17上安装Xdebug，但我在Google上找到的不同解决方案没有成功。这事我有点糊涂了。

我尝试使用PECL安装这里提到的Xdebug。

但我只得到消息:

#7 ERROR: process "/bin/sh -c pecl install xdebug" did not complete successfully: exit code: 127
------
> [ 3/34] RUN pecl install xdebug:
#7 0.416 /bin/sh: pecl: not found
------
Dockerfile:30
--------------------
28 |         composer
29 |     
30 | >>> RUN pecl install xdebug
31 |     RUN docker-php-ext-enable xdebug
32 |     
--------------------
ERROR: failed to solve: process "/bin/sh -c pecl install xdebug" did not complete successfully: exit code: 127

这是我的Dockerfile:

我已经尝试添加$PHPIZE_DEPS，或者使用php8.1-pecl-xdebug代替PECL install。此外，正如您所看到的，我添加了musl-dev和gcc到apk添加，但无济于事。我还发现，有更多的人在Alpine (https://github.com/docker-library/php/issues/1134)下有PECL问题，但这似乎不是我的问题。

对于如何解决这个问题，有什么建议吗?

线索在:#7 0.416/bin/sh: pecl: not found.

如果你想使用pecl，你需要在安装apk的同时安装php81-pear，但是一般来说，当php81-pecl-xdebug这样的包已经可用时，你不应该编译你自己的扩展。

你没有说为什么安装那个不工作。
