Happened the same to me on debian stretch. I supposed it was because my NPM install was done with APT.

I've tried another VM with Ubuntu 20.04, with Node installed from NVM and then:

# npm -g install @cloudflare/wrangler
/root/.nvm/versions/node/v10.20.1/bin/wrangler -> /root/.nvm/versions/node/v10.20.1/lib/node_modules/@cloudflare/wrangler/run-wrangler.js

> @cloudflare/wrangler@1.10.3 postinstall /root/.nvm/versions/node/v10.20.1/lib/node_modules/@cloudflare/wrangler
> node ./install-wrangler.js

internal/modules/cjs/loader.js:638
    throw err;
    ^

Didn't work either.

Other packages like express install just fine:

~# npm install -g express
+ express@4.17.1

So after a decent amount of time spent, I just grabbed the binary from here: https://github.com/cloudflare/wrangler/releases/download/v1.10.3/wrangler-v1.10.3-x86_64-unknown-linux-musl.tar.gz

And then the python example didn't worked on Debian 9 (probably due to python 3.5). I tried again in the Ubuntu 20.04 VM (where I've installed the binary directly too).

I tried to import json to serialize/deserialize from python and it shows the error:
Can't import module 'codecs'

Having problem installing the tool and then it's not possible to do more than a hello world at python makes me think it's worth to rely on workers at the moment if you aren't trying to use javascript.

you might need to update node

I'm on node 15 and have the same issue.

• npm install @cloudflare/wrangler
• run npm run publish using example package json below, get the above error

example package.json:

{
  "private": true,
  "dependencies": {
    "@cloudflare/wrangler": "^1.11.0"
  },
  "scripts": {
    "worker:publish": "wrangler publish"
  }
}

I was having the same issue. I was unable to get the npm install to work, but I was able to get cargo install wrangler to work by installing perl.
I'm on Fedora Linux so sudo dnf install perl -y worked for me :)

@rodrigopv it looks like you're trying to run npm install -g @cloudflare/wrangler as root, since /root is appearing in your error message.

The wrangler npm installer does not support running as root, as npm runs the postinstall script as the nobody user to prevent malicious postinstall scripts from causing damage to your system. Please re-open this issue if you're unable to get the npm installer to work as a non-root user.

Hi,
I managed to solve the permission issue with ubuntu by doing the followings at below:

1. Open terminal and paste the following codes.
   mkdir "${HOME}/.npm-packages"
npm config set prefix "${HOME}/.npm-packages"

2. Use nano editor
   nano ~/.bashrc

3. Paste the following codes at the bottom => .bashrc
   NPM_PACKAGES="${HOME}/.npm-packages"
export PATH="$PATH:$NPM_PACKAGES/bin"
export MANPATH="${MANPATH-$(manpath)}:$NPM_PACKAGES/share/man"

4. Finally
   source ~/.bashrc
npm install -g @cloudflare/wrangler

Hope this helps. Happy coding....

Solved this by simply using yarn instead of npm.
