SyntaxError: Cannot use import statement outside a module [solved]-CodePudding

I really went trough all the duplicates of this question, and no solution has worked. This is something different.

My project works perfectly on my local machine, but as soon as I run it on a server, I get this error: > ts-node ./src/index.ts

SyntaxError: Cannot use import statement outside a module.

Nothing is run in the browser.

It is just server side ts

/root/ae-system/node_modules/rithmic-api/src/index.ts:1
import os from 'os'
^^^^^^

[ERROR] 13:49:17 SyntaxError: Cannot use import statement outside a module

The error above occurs at a local npm module. The module was not installed from the npm registry but is a custom typescript project.

The dependency was added at the main folder:

package.json

...
  "dependencies": {
    "rithmic-api": "file:rithmic-api",
  }
...

I don't know if it is caused because of this.

My local npm and node versions are almost equal to the server versions:

node is > 19 npm is > 8

As for the Typescript configurations:

the custom npm module has

tsconfig.json


{
    "compilerOptions": {
        "target": "ESNext",
        "module": "CommonJS",
        "outDir": ".dist/src",
        "moduleResolution": "node",
        "listFiles": false,
        "alwaysStrict": true,
        "noUnusedLocals": false,
        "noImplicitReturns": true,
        "noImplicitThis": true,
        "noImplicitAny": true,
        "strictNullChecks": true,
        "noFallthroughCasesInSwitch": true,
        "forceConsistentCasingInFileNames": true,
        "pretty": true,
        "sourceMap": false,
        "types": ["node"],
        "esModuleInterop": true,
        // "declaration": true,
        // "rootDir": "sys",
        // "skipLibCheck": true,
        // "noStrictGenericChecks": true,
        // "noUnusedParameters": false,

        // "emitDecoratorMetadata": true,
    },
    "include": ["./src/**/*.ts"],
    "exclude": ["node_modules"],
}

the main project folder has


{
    "compilerOptions": {
        "target": "ESNext",
        "module": "CommonJS",
        "outDir": ".dist/src",
        "moduleResolution": "node",
        "listFiles": false,
        "alwaysStrict": true,
        "noUnusedLocals": false,
        "noImplicitReturns": true,
        "noImplicitThis": true,
        "noImplicitAny": true,
        "strictNullChecks": true,
        "noFallthroughCasesInSwitch": true,
        "forceConsistentCasingInFileNames": true,
        "pretty": true,
        "sourceMap": false,
        "types": ["node"],
        "esModuleInterop": true,
        // "declaration": true,
        // "rootDir": "sys",
        // "skipLibCheck": true,
        // "noStrictGenericChecks": true,
        // "noUnusedParameters": false,
        // "experimentalDecorators": true,
        // "emitDecoratorMetadata": true,
    },
    "include": ["src/**/*.ts"],
    "exclude": ["node_modules"],
}

The main scripts to run the project are:

"scripts": {
    "start": "ts-node ./src/index.ts",
    "dev": "tsnd --cache-directory \".cache\" --watch \"./rithmic-api/src, ./strategy\" --respawn --clear --no-warnings ./src/index.ts",
    "build": "tsc"
  },

The issue was caused by myself or some change in npm where local packages are not linked, but installed

I used these instructions to fix the issue:

CodePudding user response：

This looks like a problem of typescript not finding your tsconfig.json file. Your config looks fine. Something that I am wondering is why don't you build everything into the dist folder and just deploy the dist folder to your server this way the modules are build into the dist? I think node running javascript is faster that ts-node running typescript.

Fixed by OP after discussion below: i fixed the problem using these instructions. geeksforgeeks.org/how-to-install-a-local-module-using-npm
