Can't find package.json in directory

[Fattah-Saqib]

Whenever I put any snarkjs command it shows the following but the package.json file is present in that directory.

 internal/fs/utils.js:269
    throw err;
    ^

Error: ENOENT: no such file or directory, open '\C:\Users\fattah\AppData\Roaming\npm\node_modules\snarkjs\package.json'

I am having the same problem

[jbaylina]

This looks like a windows problem..

[vanmoortel]

Yes, the problem is that there is a backslash at the beginning of the path.
Here is a temporary fix for windows users:

Update line 1154 of your-project/node_modules/snarkjs/build/cli.cjs
Before:
pkgS = fs.readFileSync(path.join(__dirname$1, "..","package.json"));
After
pkgS = fs.readFileSync(path.join(__dirname$1.slice(1,__dirname$1.length), "..","package.json"));

Having this issue on windows as well.

For 0.3.59, update line 151 of /node_modules/snarkjs/build/cli.cjs with

pkgS = fs__default['default'].readFileSync(path__default['default'].join(__dirname$1.slice(1,__dirname$1.length), "..","package.json"));

[calvbore]

also for v0.3.59, changed line 5744 of /node_modules/snarkjs/build/cli.cjs to:

templateName = fs__default['default'].readFileSync(path__default['default'].join(__dirname$2.slice(1,__dirname$1.length), "..","templates","verifier_groth16.sol"));

and haven't run into any issues on windows yet.

[tippi-fifestarr]

Using Node 14.15.0 npm install -g snarkjs@latest installs "correctly" but no node_modules or package.json are created

[Komari-Koshigaya]

also for v0.3.59, changed line 5744 of /node_modules/snarkjs/build/cli.cjs to:

templateName = fs__default['default'].readFileSync(path__default['default'].join(__dirname$2.slice(1,__dirname$1.length), "..","templates","verifier_groth16.sol"));

and haven't run into any issues on windows yet.

Is this problem still unresolved?
I have the same problem, and there is another question after taking your approach

This problem has re-emerged on windows again, v0.4.15

I fixed it via the this code block in PR #88 : https://github.com/iden3/snarkjs/pull/88/files#diff-479f878ecd4b45fdc75718d1eedb8d4385d08d50264852cc6c0570ec310c1733R152 and changing the __dirname$1 to __dirname$2

[phated]

I believe this was fixed by #131 - please update to snarkjs 0.4.16 and try again.
