What could be causing the issue with npm modules installation?

I've been having trouble installing the react-native-cli module, as well as any other module.

Here's what I've tried:

npm install -g react-native-cli

When I run this command in the terminal, I keep getting an error. I've used node on Windows before and had no issues with installation, but now that I'm using a Mac, things seem to be going wrong.

I'm questioning whether node is actually installed properly. When I type "node" in the terminal, the prompt changes from $ to >, which seems like a positive sign. I can even run simple commands like:

node > console.log('Hello World!');

and it works fine. But when I try:

node > --version

it doesn't work.

So, is node correctly installed on my system? What am I missing here?

Answer №1

Give this a shot

Run the following command to install the react-native-cli globally:
sudo npm install -g react-native-cli

To verify the version, type the following in your terminal:

node --version

Appreciate it!

Answer №2

If you're experiencing issues with write permissions in the bin directory that npm is using for global installation, one simple solution is to use the sudo command:

sudo npm install -g react-native-cli

However, some may suggest that a better approach would be to adjust the setup so that you have the necessary write privileges without relying on sudo. This method will require administrative privileges on your Mac.

When checking the node version, remember not to include the >. Instead, use node --version.

To determine the exact binary associated with the node command, you can utilize either type -a node or which node.

Answer №3

If you can successfully run console.log('Hello World!');, then your node installation should be working correctly.

To verify the version from the command line, simply type:

C:\Users\athakur>node --version
v12.18.3

In the Node.js console, enter the following command:

> console.log(process.versions);
{ http_parser: '2.9',
  node: '12.18.3',
  v8: '7.8.279.23-node.34',
  uv: '1.36.0',
  zlib: '1.2.11',
  ares: '1.16.1',
  modules: '72',
 nghttp2: '1.41.0' }
