react-native：从纱线切换到 npm

Question

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?

Answer 1

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

Answer 2

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.

Answer 3

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.
