This is likely due to using a lockfileVersion of 3 (produces the same stack trace) and will be fixed by https://github.com/ds300/patch-package/pull/434.

I solved the problem in this way

1. converted package-lock to version=2
2. npx patch-package your-package
3. return back package-lock to version=3

[el-j]

1. convert your lockfile to version 2

   npm shrinkwrap --lockfile-version 2

2. edit node_modules/react-scripts/scripts/build.js and change line 12 | 13 + 58:

   
   // process.env.BABEL_ENV = "production"
   // process.env.NODE_ENV = "production"
   process.env.BABEL_ENV = process.env.NODE_ENV
   process.env.NODE_ENV = process.env.NODE_ENV

// const config = configFactory("production"); const config = configFactory(process.env.NODE_ENV);

3. use patch-package to create a patch:

npx patch-package react-script

4. **package.json** change `build` and add `build-dev`  + `postinstall` patch
```json
"scripts": {
...
"build": "NODE_ENV=production react-scripts build",
"build-dev": "NODE_ENV=development react-scripts build",
"postinstall": "npx patch-package"
...
},

5. create lockfile version 3

   npm shrinkwrap --lockfile-version 3

6. rename shrinkwrap.json to package-lock.json

thanks for the idea @alekseyBatuhtin @zqianem

Issue happens with npm 9.2.0, which is currently bundled with the latest stable node version. Installing node LTS with npm 8.19.2, removing the lockfile and generating a new one, can also be used as a workaround until #434 lands.

Anyone tried to use patch-package to patch patch-package so you can run patch-package?

[tobua]

Update has been released in 6.5.1 and is working fine, thanks!

In my case I realized that somehow there are both package-lock and yarn.lock in my project. I use yarn mainly so after deleting package-lock error gone.

This is happening to me with patch-package 7.0.0 and patch-package 8.0.0 on Node.js v18.14.0 with a "lockfileVersion": 3:

npx patch-package localForage 
patch-package 8.0.0

Node.js v18.14.0

就我而言，我意识到我的项目中同时存在package-lock和yarn.lock。我主要使用纱线，所以删除后package-lock错误就消失了。

good idea
