I have a JavaScript project using npm to manage its dependencies. I'm trying to migrate to Yarn.
When I run yarn install in the console, it gives me an error:
An unexpected error occurred: "ENOENT: no such file or directory, chmod C:\....\node_modules\.bin\esparse"
From what I read on the yarn docs, just running yarn install should be enough. Why doesn't this work as expected?
I am using Yarn 0.17.0, npm 2.14.12 and Node 4.2.4.

Whenever you run yarn (which is the equivalent of running yarn install ) upon a fresh install, a yarn. lock file is generated. It lists the versions of dependencies that are used at the time of the installation process. That means it looks into your package.
Yarn can consume the same package. json format as npm, and can install any package from the npm registry. This will lay out your node_modules folder using Yarn's resolution algorithm that is compatible with the node. js module resolution algorithm.
yarn install is used to install all dependencies for a project. This is most commonly used when you have just checked out code for a project, or when another developer on the project has added a new dependency that you need to pick up. If you are used to using npm you might be expecting to use --save or --save-dev .
The Yarn maintainers recommend installing Yarn globally by using the NPM package manager, which is included by default with all Node. js installations. Use the -g flag with npm install to do this: sudo npm install -g yarn.
The following Solution worked for me
rm -rf node_modules **/node_modules
rm -rf yarn.lock **/yarn.lock
yarn cache clean
yarn install
