react-native: switch from yarn to npm

问题:

Is there a step-by-step process to change a react-native project from using yarn as the package manager to using npm? All I can find after several days of searching are instructions to go from npm to yarn and a package called deyarn which doesn't seem to fully work for me. Does anyone have a good resource on this?

Try this :

• Remove yarn.lock (don't need this file).
• Remove folder node_modules
• In package.json, change script use yarn to the same command with npm
• Remove all global package of yarn (don't need to remove if you want to use npm for one project)
• Remove yarn if you don't want to use it again.
• Install npm (if you installed, ignore this step)
• Install global and local package you need

Can you upload some error, you said that not fully work.

Edit:

If you want to change npm to yarn, it same:

• Remove package-lock.json (don't need this file).
• Remove folder node_modules
• In package.json, change script uses npm to the same command with yarn
• Remove all global package of npm (don't need to remove if you want to use yarn for one project)
• Remove npm if you don't want to use it again.
• Install yarn (if you installed, ignore this step)
• Install global and local package you need

You can see CLI commands comparison for 3rd step

You can try taking the following steps:

1. Remove node_modules
2. Run npm install

This should work because npm and yarn use the same package.json.

The deyarn package worked brilliantly for me.

Note that it will only flag (not auto-update) any package-lock.json scripts that you may need to update.

Depending on your environment needs, you may also want to strip out the engines: yarn: '..' entry it adds to your package-lock.json.
