Windows 10 和 Linux 的 Windows 子系统上的 NodeJS

Question

I'm trying to get Expo, a platform for making native mobile apps, to run on a Windows 10 machine. A preprequisite for Expo is NodeJS so I installed that. However, I ran into some issues getting Expo to work using Git Bash and so now I'm trying to get Windows Subsystem for Linux (WSL) operational to use that instead. Ubuntu 18.04 LTS has been downloaded and initialized. Using a CMD here is what's happening:

C:\Users\jason.black>node -v
v12.13.0

C:\Users\jason.black>wsl
jason@PC1:/mnt/c/Users/jason.black$ node -v

Command 'node' not found, but can be installed with:
sudo apt install nodejs

jason@PC1:/mnt/c/Users/jason.black$ sudo apt install nodejs
[sudo] password for jason:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package nodejs
jason@PC1:/mnt/c/Users/jason.black$

So it appears that NodeJS which was initially installed is not available to WSL. Does that seem right? And why won't it install so WSL can access it?

Answer 1

If you're trying to access Node installed on the windows site, you may specify the PATH to /mnt/x/.../path/to/node/bin; if you're trying to install nodejs on the Linux side, may be you're looking for the package 'node' (not nodejs), or you can just download the portable version:https://nodejs.org/dist/v12.13.1/node-v12.13.1-linux-x64.tar.xz

For someone who's not familiar to Linux:

# will be download to home directory
cd ~
# using wget
wget https://nodejs.org/dist/v12.13.1/node-v12.13.1-linux-x64.tar.xz
# using curl
curl -o node-v12.13.1-linux-x64.tar.xz https://nodejs.org/dist/v12.13.1/node-v12.13.1-linux-x64.tar.xz
# extract
tar xf node-v12.13.1-linux-x64.tar.xz
