解决的问题

nvm solves the problem of juggling multiple Node.js versions for different projects or testing environments. It allows per-project version pinning via .nvmrc and supports migrating global packages between versions, which is essential for developers working on legacy and modern codebases.

部署现实

当前可用的安装信号是：curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.6/install.sh | bash。这只能作为起点，正式使用前建议让 Codex 或 Claude 检查 README、环境变量、运行时版本和部署目标。

商业可用性

当前记录的许可证是 MIT。这是重要的商业使用信号，但仍应核验许可证全文、依赖许可证、模型/API 条款和商标限制。

能力上限

The project supports all POSIX shells and platforms including macOS, Linux, and WSL, with features like .nvmrc, offline install, mirrors, and custom colors. It is a mature, battle-tested tool with a large user base, but it is not designed for Windows natively (requires WSL) and lacks some features like automatic version switching without shell integration.
