我正试图用带有VSCode的Lando(3.0.24版(设置Xdebug，但没有成功。我已经在互联网上阅读了官方指南和其他内容，以及与我问题相似的不同主题，但遗憾的是，我无法使其发挥作用。
我的lando文件位于docroot文件夹中，它是：
name: mysite
recipe: drupal9
services:
appserver:
webroot: .
xdebug: debug
config:
php: ../.vscode/php.ini
php.ini文件是：
[PHP]
; Xdebug
xdebug.max_nesting_level = 256
xdebug.show_exception_trace = 0
xdebug.collect_params = 0
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_host = ${LANDO_HOST_IP}
xdebug.log = /tmp/xdebug.log
; Remote settings
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_host = ${LANDO_HOST_IP}
; xdebug.remote_connect_back = 1
xdebug.remote_log = /tmp/xdebug_remote.log
最后，launch.json文件是：
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug (9003)",
"type": "php",
"request": "launch",
"port": 9003,
"log": true,
"pathMappings": {
"/app/": "${workspaceRoot}/",
}
}
]
}
顺便说一句，我不确定pathMappings是如何设置的，所以我尝试了不同的组合，比如
- "app/"："{workspaceRoot}/">
- "app/"："{workspaceRoot}/docroot">
- "app/"："{workspaceFolder}/">
- "app/"："{workspaceFolder}/docroot">
无论如何，问题是Xdebug没有在断点处停止。
如果我跟踪xdebug.log，我会看到：

所以也许Xdebug仍然无法连接到正确的IP？不管怎样，你知道怎么解决这个问题吗？谢谢
编辑：如果我把lando.yml文件从dooclot文件夹移到上面的文件夹，我可以得到一个有点工作的情况，Xdebug实际上在VSCode中停止。然而，还有另外两个问题：
- 无法再使用
lando drush。对此的变通方法是CCD_ 4；全局"；兰多的德鲁什不起作用 - 终端命令(例如drush(似乎不适用于xdebug(至少对我来说是一个非常小的问题(，因为它们返回
Xdebug:[Step Debug]无法连接到调试客户端。已尝试：172.31.206.147:9003(通过xdebug.client_host/xdebug.client_port回退(：-(
在更新的php.ini和lando.yml文件下面，launch.json与上面的相同。
[PHP]
; Xdebug
xdebug.max_nesting_level = 512
xdebug.show_exception_trace = 0
xdebug.collect_params = 0
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_host = ${LANDO_HOST_IP}
xdebug.log = /tmp/xdebug.log
xdebug.remote_log = /tmp/xdebug_remote.log
name: myproject
recipe: drupal9
services:
appserver:
webroot: docroot
xdebug: debug
config:
php: .vscode/php.ini
我不确定这是否是你的情况，但我会告诉你我是如何解决这个问题的：
我通过将此行添加到php.ini(在/etc/php/7.4/cli/php.ini中(来解决将error_log指向有效位置的问题：
error_log = /var/www/log/php_error.log
请将该位置更改为所需的任何有效目录，然后重试。警告应该从输出中消失，现在转到日志文件。
