# 安装 Javy（JS→WASM 编译工具）到服务器
|
||
# ------------------------------------------------------------
|
||
# 用法：bash deploy/install_javy.sh
|
||
# 作用：从 GitHub 官方 Releases 下载 Javy（约 14MB 单文件），
|
||
# 校验 SHA256 后安装到 /usr/local/bin/javy
|
||
# 幂等：已安装且版本一致时直接跳过，可重复执行
|
||
# 体积说明：下载包约 14MB，解压后约 40MB，仅占磁盘少量空间
|
||
# ============================================================
