[BUG] JavaScript heap out of memory

[sauron4nn]

在WSL2环境下通过命令 npx @deepseek-ai/dsh web 启动dsh时遇到OOM问题，以下是完整输出：

env NODE_OPTIONS="--max-old-space-size=4096" npx @deepseek-ai/dsh web

same problem here, cannot execute in my 1GB VPS, jesus christ guys

why the hell we live in 2026 and people creating those things in nodejs, let move forward to another real frameworks/languages

这是 Node 24 默认堆大约 2GB、npx 解 @deepseek-ai/dsh@0.1.1-rc.1 这棵树时顶满了，不是 Web 服务本身泄漏。上面 NODE_OPTIONS=4096 还能继续用 npx，每次都会再解一份临时目录，只是把爆炸推迟。#3683 同一条。

长期用法：

export NODE_OPTIONS=--max-old-space-size=8192
npm install -g @deepseek-ai/dsh@latest   # 现在 latest = 0.1.1-rc.1
dsh web

能换 Node 22 的话更稳，22 有人用裸 npx 都能撑过去。pnpm dlx 同样会解临时树，只是进度好看一些。1GB 内存的 VPS 装不下这棵依赖图，换一台至少 8GB 的机器，或在本机装全局再把 UI 打过来。

我使用npm install解决了这个问题，命令如下：
npm install -g --allow-scripts=@deepseek-ai/dsh-subprocess-local,koffi,node-pty,@google/genai,protobufjs @deepseek-ai/dsh

有用

Errors with 4GB also. Going to wait before this gets sorted as opposed to continue cranking up the available heap. Kinda crazy.
