Wrangler: Unable to install wrangler globally inside a Docker container when I have root access.

[dompuiu]

🐛 Bug Report

I am trying to install wrangler inside a Docker container using the NPM -g flag. The Node was installed inside the container using NVM.

Environment

• operating system: Ubuntu 18.04
• output of rustc -V:
• output of node -v: v13.0.1
• output of wrangler -V:

Steps to reproduce

1. You need to have docker install on your machine.

2. Start an Ubuntu container:

   docker run -it ubuntu
   

   You will get inside the bash of that container.

3. Install curl:

   apt-get update && apt-get install curl
   

4. Install NVM:

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.0/install.sh | bash
   

5. Load NVM:

   export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
   [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
   

6. Install a node version:

   nvm install stable
   

7. Install wrangler:

   npm i -g @cloudflare/wrangler
   

What did you expect to see?

I was hoping wrangler would get installed.

What did you see instead?

Hey @dompuiu, I did something similar recently with the wrangler GitHub action integration we just launched:

https://github.com/cloudflare/wrangler-action/blob/master/entrypoint.sh

Maybe that'd be helpful? FWIW, I think those containers run with a user github so maybe the root part here would cause the instructions to differ a bit. Other folks on the team might know more about that than me 😬

[dompuiu]

I've tried to use some commands from that file. But I was still not able to make it work.

As a side note, I tried also installing node using the following commands (so no NVM):

apt-get update && apt-get -y install curl
curl -sL https://deb.nodesource.com/setup_11.x  | bash -
apt-get -y install nodejs

With the node installed this way I get a different error:

Error: EACCES: permission denied, mkdir '/root/.wrangler'

Even if I create the $HOME/.wrangler folder with 777, I still get the same error. Maybe you should check to see if the .wrangler folder exists before calling the mkdir command.

I've been unable to install on MacOSX for months. Block by the same issue. Running as sudo. Re-installed node & npm.

Error: EACCES: permission denied, mkdir '/Users/user1/.wrangler'

Even if I create all the directories manually the script tries to create them iself instead of checking first and fails.

[EverlastingBugstopper]

@bladerunner41 Unfortunately, EACCES errors are not something we can fix in Wrangler as it's a product of the node ecosystem. We recommend using nvm, but there are alternative solutions outlined here: https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

For @dompuiu, I'd maybe try running nvm use stable in the same directory that you're trying to install wrangler from, and also making sure that which nvm points to a .nvm directory. If that doesn't work, I'd recommend installing with cargo install wrangler

[signalnerve]

Hey @dompuiu! I think you were actually _very_ close to getting this working in your initial bug report. As per the README, we recommend installing Wrangler via NVM or a similar Node package manager, as it should simplify any potential permissions issues.

In your original bug report, it seems like things work until you get to installing Wrangler. In my GitHub action code, I set the WRANGLER_HOME directory, to make sure that wrangler installs into a known directory with good permissions. Here's what I did:

export HOME="/github/workspace"
export NVM_DIR="/github/workspace/nvm"
export WRANGLER_HOME="/github/workspace"

mkdir -p "$HOME/.wrangler"
chmod -R 770 "$HOME/.wrangler"

FWIW, I'd also make sure that whenever you're using npm, such as npm install -g @cloudflare/wrangler, be sure that you're not using sudo! Doing so will mess up the permissions for your NPM packages and would definitely cause an error here.

[dompuiu]

@signalnerve I was able to make it work using some of the steps you provided. Thanks!

For anyone interested these are the steps that I run inside the ubuntu container:

apt-get update && apt-get install -y curl

mkdir github
export HOME="/github"
mkdir -p "$HOME/.wrangler"
chmod -R 770 "$HOME/.wrangler"

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.0/install.sh | bash

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

nvm install stable
npm i -g @cloudflare/wrangler

My real setup is more complicated, but I will be able to make it work.

I think the lesson is that you cannot install the wrangler tool as root using the default HOME directory.

[signalnerve]

Ah, exciting that you got it working! Please let us know if there's anything in particular you think we should do to make documentation around this better. Thanks @dompuiu!

[ashleygwilliams]

i think this issue is now resolved- so i am going to close! i do think we should better document these features- and have filed this issue to track that work: https://github.com/cloudflare/workers-docs/issues/481 thanks everyone!

[blackn1ght]

Apologies for re-opening this, however I came across this issue and the above steps didn't work (for my node environment, not ubuntu) - however for future readers, the following worked for me:

FROM node:12.13.0

WORKDIR /app
COPY package.json package.json
RUN npm i -g @cloudflare/wrangler --unsafe-perm=true --allow-root
RUN npm i
RUN wrangler --version

[bladerunner41]

thx @blackn1ght soved my problem.

[rochapablo]

Fixing my npm following did work.

[abury]

@blackn1ght you legend! I've been trying to crack this for hours. This is what did the trick for me

This saved me. Thanks @dompuiu
I was having problem with postscript execution while installing nodejs via apt-get at wrangler installation. I am assuming this to be some kind of wrangler bug which I cannot figure out exactly. Also tried cargo and failed in an epic way even after successful build.

Finally I found this code while searching for solution here.

Following is for people like me who have hard time installing wrangler in Ubuntu
I made some tweak for myself. I am using Ubuntu 18.04 LTS

sudo apt-get update
sudo apt-get upgrade

mkdir -p "$HOME/.wrangler"
chmod -R 770 "$HOME/.wrangler"

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.0/install.sh | bash

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" 
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

nvm install stable
npm i -g npm
npm i -g @cloudflare/wrangler
node -v && npm -v && wrangler -V

Resulted in:

v14.2.0
6.14.5
 wrangler 1.8.4

also making sure that which nvm points to a .nvm directory.

there is no which nvm only command -v nvm Zuul

Quoting from: https://github.com/nvm-sh/nvm#verify-installation

Please note that which nvm will not work, since nvm is a sourced shell function, not an executable binary.

@rochapablo You fixed my issue after a few hours of getting frustrated. Thanks!
