SyntaxError：视频中 NFT 生成器代码的 JSON 输入意外结束

Question

所以我正在尝试关注这个视频： https ://youtu.be/NJVkAAZqc0k?t=205

由于某种原因，终端中使用的命令： node utils/update_info.js 对我不起作用。

这是我得到的错误：

node utils/update_info.js

未定义：1

SyntaxError：JSON 输入意外结束

这是我的代码：

const basePath = process.cwd();

const { NETWORK } = require( ${basePath}/constants/network.js ); 常量 fs = 要求（“fs”）；

const { baseUri, description, namePrefix, network, solanaMetadata, } = require( ${basePath}/src/config.js );

// 读取 json 数据 let rawdata = fs.readFileSync( ${basePath}/build/json/_metadata.json ); 让数据 = JSON.parse(rawdata);

data.forEach((item) => { if (network == NETWORK.sol) { item.name = ${namePrefix} #${item.edition} ; item.description = description; item.creators = solanaMetadata.creators; } else { item.name = ${namePrefix} #${item.edition} ; item.description = description; item.image = ${baseUri}/${item.edition}.png ; } fs.writeFileSync( ${basePath}/build/json/${item.edition}.json .json , JSON.stringify(item, null, 2) ); });

fs.writeFileSync( ${basePath}/build/json/_metadata.json , JSON.stringify(data, null, 2) );

if (network == NETWORK.sol) { console.log( Updated description for images to ===> ${description} ); console.log( Updated name prefix for images to ===> ${namePrefix} ); console.log( Updated creators for images to ===> ${JSON.stringify( solanaMetadata.creators )} ); } else { console.log( Updated baseUri for images to ===> ${baseUri} ); console.log( Updated description for images to ===> ${description} ); console.log( Updated name prefix for images to ===> ${namePrefix} ); }

它说我在第 17 行出错了。该行的代码是：

let data = JSON.parse(rawdata);
