• How did you install nvm? (e.g. install script in readme, homebrew):
  Install script using cURL

• What steps did you perform?
  Cloned the repository then added the source lines to .bashrc
  export NVM_DIR="$HOME/.nvm"
  [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
  [ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion" # This loads nvm bash_completion

• What happened? It worked but now every time I open a new terminal or source ~/.bashrc it outputs three lines before the bash prompt, they are as follows:
  -bash: [: : integer expression expected
  -bash: [: too many arguments
  -bash: [: too many arguments

• What did you expect to happen? I expected my bash prompt to be unchanged.

• Is there anything in any of your profile files (.bashrc, .bash_profile, .zshrc, etc) that modifies the PATH? Yes, here is a copy of my .bashrc file:

 #!/bin/bash

export PATH=~/bin:$PATH
export EDITOR="nano"
export PAGER="more"

force_color_prompt=yes

# Disable BIOS beep on delete and backspace
xset -b

#history length settings see bash(1) in man bash
HISTSIZE=100000
HISTFILESIZE=200000

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '

# 
if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases

What is source "$BASH_IT"/bash_it.sh? What happens if you comment out that line?

[angryrobot]

It's a bash framework. It doesn't matter if it's commented or not I still get the same error. I have removed everything and added things back to my bash script one a a time and doing a source ~/.bashrc after each one. There is nothing in my bash script that is causing the error except the 2 NVM lines. If I leave the first one and remove the other 2 the error goes away. I'm very meticulous about how I do things and asking for help here is a last resort. I've tried everything I can think of to fix this to no avail.

[ljharb]

Is your home dir, or $NVM_DIR, a symlink? Can you share the contents of . ~/.bash_aliases?

The issue here is because nvm is a sourced shell function, so it could conflict with literally any other line in your bash sourcing path, such that commenting out the "source nvm" line would work, but also commenting out "the conflicting line" would work - we only have to find it :-) Once we do, I can see if there's a way for nvm to work around it.

@ljharb what do you think about adding a issue label like waiting for response for issues like this one?

[angryrobot]

Sorry so long to respond. I've been on vacation. Anyway I figured out why it was causing the error. In my ~/.bash_aliases I had an alias - alias="tr=tree" and that was causing the error. I renamed it and everything works fine now. @ljharb thank you for all of your help.

[PeterDaveHello]

okay, I know how to fix it now, something like what I guess, PR #1735 sent now, with that fix, you should be able to keep your personal aliases :)
