bug

What is the current behavior?

yarn install completes successfully but no yarn.lock is written and no "Saved lockfile" message is displayed.

If the current behavior is a bug, please provide the steps to reproduce.

Here is an example package.json:

```json { "name": "react-element-to-jsx-string", "version": "11.0.0", "description": "Turn a ReactElement into the corresponding JSX string.", "main": "dist/index.js", "scripts": { "build": "babel ./src/ --ignore=*.spec.js --source-maps --out-dir ./dist/", "lint": "node_modules/.bin/eslint .", "lint:fix": "npm run lint -- --fix", "flow": "flow", "precommit": "lint-staged", "prepublish": "npm run build", "prebuild": "mkdir -p dist && rm -rf ./dist/*", "prettier:fix": "prettier --write --single-quote --trailing-comma es5 \"{src/**/*.js,package.json}\"", "test": "jest && npm run lint", "test:watch": "jest --watch", "release": "./release.sh" }, "lint-staged": { "*.js": [ "prettier --write --single-quote --trailing-comma es5", "git add" ] }, "author": { "name": "Algolia, Inc.", "url": "https://github.com/algolia" }, "license": "MIT", "repository": "algolia/react-element-to-jsx-string", "devDependencies": { "babel-cli": "6.24.1", "babel-eslint": "7.2.3", "babel-jest": "20.0.3", "babel-plugin-lodash": "3.2.11", "babel-preset-es2015": "6.24.1", "babel-preset-flow": "6.23.0", "babel-preset-react": "6.24.1", "babel-preset-stage-2": "6.24.1", "babel-register": "6.24.1", "conventional-changelog-cli": "1.3.2", "doctoc": "1.3.0", "eslint": "4.2.0", "eslint-config-algolia": "12.0.0", "eslint-config-prettier": "2.3.0", "eslint-plugin-import": "2.7.0", "eslint-plugin-jest": "20.0.3", "eslint-plugin-prettier": "2.1.2", "eslint-plugin-react": "7.1.0", "expect": "1.20.2", "flow-bin": "0.50.0", "husky": "0.14.3", "jest": "20.0.4", "json": "9.0.6", "lint-staged": "4.0.2", "mversion": "1.10.1", "prettier": "1.5.3", "react": "15.6.1", "react-dom": "15.6.1", "react-test-renderer": "15.6.1" }, "peerDependencies": { "react": "^0.14.8 || ^15.0.1" }, "dependencies": { "collapse-white-space": "^1.0.3", "is-plain-object": "^2.0.4", "lodash": "^4.17.4", "sortobject": "^1.0.0", "stringify-object": "^3.2.0" } } ```

Then run yarn install --ignore-scripts. This fails to generate a yarn.lock for me on both Ubuntu 16.04 and OSX.

What is the expected behavior?

yarn.lock should be written

Please mention your node.js, yarn and operating system version.

yarn v0.27.5. Tried on both Ubuntu 16.04 and OSX. Also tried on both node 8.x and 6.x. Most recently trying on v6.11.1.

Sorry for false alarm, I have found a --install.pure-lockfile true .yarnrc :(
