I know i'm probably late but i was faceing the same issue. Finally I got a work around if you want to try. In your tsconfig.json add "node_modules/@types/node" in "typeRoots" as you can see in the config bellow:
我知道我可能迟到了，但我遇到了同样的问题。如果您想尝试，我终于找到了解决方法。在您的 tsconfig.json 中，在“typeRoots”中添加“node_modules/@types/node”，如下面的配置所示：
{
"compileOnSave": false,
"compilerOptions": {
"baseUrl": "./",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"downlevelIteration": true,
"experimentalDecorators": true,
"module": "esnext",
"moduleResolution": "node",
"importHelpers": true,
"target": "es2015",
"typeRoots": [
"node_modules/@types",
"node_modules/@types/node"
],
"lib": [
"es2018",
"dom"
]
}
}

This solved the issue for me:
这为我解决了这个问题：
npm install @types/node
回答by Pistolpete .
Are you running this in Node?
你是在 Node 中运行这个吗？
Why not
import fs from fs?
为什么不
import fs from fs呢？
Also try requireand see what's up
也尝试require看看发生了什么
