问题描述

Unable to watch for file changes in this large workspace folder. Please follow the instructions link to resolve this issue.

原因分析

工作目录的文件过多，导致 VS Code File Watcher 的句柄用完了，而无法检测全部文件的变更。

解决方案

忽略不必要的文件：

# .vscode/settings.json
{
    "files.watcherExclude": {
        "**/.git/objects/**": true,
        "**/.git/subtree-cache/**": true,
        "**/node_modules/*/**": true,
        "**": false
    }
}

增加文件句柄数：

# /etc/sysctl.conf
fs.inotify.max_user_watches=524288
