问题描述
我正在尝试使用 NCC 转译和捆绑我的打字稿项目，但出现了一个奇怪的错误，我似乎无法理解，也无法在 google 上找到任何参考。我正在从命令行运行 NCC：
❯ yarn run ncc build ./test.ts -o build/
注意：“test.ts”的内容只是：console.log('Hello!');
并得到以下输出：
ncc: Version 0.26.2
ncc: Compiling file index.js
Error: Module build failed (from ./node_modules/@vercel/ncc/dist/ncc/loaders/ts-loader.js):
Error: Could not load TypeScript compiler with NPM package name `/home/edu/repos/some-project/node_modules/@vercel/ncc/dist/ncc/typescript.js`. Are you sure it is correctly installed?

TypeScript 和 NCC 都是本地安装的。我已经尝试了两者的全球安装，结果是一样的。
如果我尝试使用 ts-node 做同样的事情，我也会得到一个错误：
❯ yarn run ts-node test.ts
yarn run v1.22.0
$ /home/edu/repos/WB-DataCollectorService/node_modules/.bin/ts-node test.ts

这是我的 package.json：
{
"name": "some-project","version": "1.0.0","main": "src/index.ts","license": "MIT","dependencies": {
"@vercel/ncc": "^0.26.2","async-mqtt": "^2.6.1","chalk": "^4.1.0","graphql-request": "^3.4.0","is-ip": "^3.1.0","lowdb": "^1.0.0","mem": "^8.0.0","moleculer": "^0.14.11","mqtt": "^4.2.6","nats": "^1.4.12","node-opcua": "^2.28.3","rxjs": "^6.6.3","typescript": "^4.1.3","winston": "^3.3.3","ts-node": "8.10.2"
},"devDependencies": {
"@types/lowdb": "^1.0.9","@types/node": "^14.14.16"
},"scripts": {
"dev": "ts-node src/index.ts","debug": "node --inspect -r ts-node/register src/index.ts"
}
}
我尝试了许多不同版本的 typescript 和 ncc，以及 package.json 中的许多其他更改，但它总是相同的。
与我的 tsconfig.json 相同，没有任何更改有所不同，无论如何这是当前的 tsconfig.json：
{
"compilerOptions": {
"outDir": "build","target": "ES2019","lib": [
"es6","dom","es2017","es2018","es2019"
],"esModuleInterop": true,"module": "commonjs","moduleResolution": "node","experimentalDecorators": true,"emitDecoratorMetadata": true,"resolveJsonModule": true
}
}
我正在运行节点版本 12.19.0。
我的想法不多了，不知道还能在哪里查看，其他项目（至少有八个）使用 TypeScript、NCC、ts-node 等完美运行......相同的 tsconfig.json 文件和构建命令...
预先感谢您的帮助！
