Unable to import the ZkProgram from o1js

[devout tiger]

Now that the Experimental is deprecated we are importing ZkProgram directly but when I am trying to do so I am getting the following error: Module '"o1js"' has no exported member 'ZkProgram'.

So, I am importing from here : import { ZkProgram } from 'o1js/dist/node/lib/proof_system';

But while compiling I am getting the following issue:

I am on this version.

Check your tsconfig.json. It should have options like those:

  "compilerOptions": {
    "target": "es2021" /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', 'ES2018', 'ES2019', 'ES2020', 'ES2021', or 'ESNEXT'. */,
    "lib": ["es2021", "dom"],
    "module": "commonjs" /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', 'es2020', or 'ESNext'. */,
    "outDir": "./dist/lib/ts" /* Redirect output structure to the directory. */,
    "strict": true /* Enable all strict type-checking options. */,
    "esModuleInterop": true /* Enables emit interoperability between CommonJS and ES Modules via creation of namespace objects for all imports. Implies 'allowSyntheticDefaultImports'. */,
    "skipLibCheck": true /* Skip type checking of declaration files. */,
    "forceConsistentCasingInFileNames": true /* Disallow inconsistently-cased references to the same file. */,
    "composite": true,
    "resolveJsonModule": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "strictPropertyInitialization": false
  },

I can see this:

{
  "compilerOptions": {
    "target": "es2020",
    "module": "es2022",
    "lib": ["dom", "esnext"],
    "outDir": "./build",
    "rootDir": ".",
    "strict": true,
    "strictPropertyInitialization": false, // to enable generic constructors, e.g. on CircuitValue
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "esModuleInterop": true,
    "moduleResolution": "node",
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "allowJs": true,
    "declaration": true,
    "sourceMap": true,
    "noFallthroughCasesInSwitch": true,
    "allowSyntheticDefaultImports": true
  },
  "include": ["./src"]
}

Should I change it ?

[zenith crag]

Yes, you can try to change options and see if it will help or not. Also, if you use yarn, it can be the result of PnP

[devout tiger]

Oh Okay.
I am using npm.

Let me try

[zenith crag]

Also, try to move o1js from peerDependencies to dependencies

[devout tiger]

Oh okay

[zenith crag]

and fresh npm install after removing all npm files can also help

[devout tiger]

Okay

o1js version need to be change right ?

[zenith crag]

I would put the 0.14.1 or 0.14.2

[devout tiger]

Okay will try with 0.14.1 if still didn't worked will try with .2

Thanks alot.
Let me try and share if it works or not

I've upgraded today typescript dependencies and have got similar errors for jest, o1js, etc...
Downgraded the typescript back, and now everything is working again. Those are my versions:
