# Web 3.0 (IOTA Intergration-service sdk)
###### tags: `區塊鏈` `IOTA`

### 遇到安裝錯誤

1. 刪除 typebox.js 的 `schemas;`
2. 遇到: `ReferenceError: TextEncoder is not defined`，就在`node_modules/whatwg-url/lib/encoding.js` 加上 `const {TextDecoder, TextEncoder} = require("util");`
3. 注意都改成 SSI_BRIDGE_URL=http://localhost:3000、AUDIT_TRAIL_URL=http://localhost:3000
4. `.env` 參考如下:
