So I installed emscripten the wasm compiler for C/C++ the other day and the path that was added to my bashrc always seems to start a new terminal shell with telling me that the paths have been added and the user color on the terminal is changed.

I can fix this by doing source ~/.bashrc and the normal color comes back but I was wondering what exactly is going on here and if there is a possible fix?

Here are some screenshots to show you how it looks:

Any insight or tips would be very much appreciated!

Edit these are the files you were looking to see:

Edit #2 : When I attempt to just run lines starting from the nvm command:

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

After the line with the # This loads nvm command then the nvm command now works.

My yarn command does not work before but does after running:

export PATH="$HOME/.yarn/bin:$HOME/.config/yarn/global/node_modules/.bin:$PATH"

The minecraft paper server command does not work even after:

alias paper='. /home/doom/Desktop/Minecraft/Paper/paper'

The emcc command does however work before and after trying these lines:

export PATH=$PATH:"$HOME/doom/Desktop/RoseDevelopment/emsdk"
export PATH=$PATH:"$HOME/doom/Desktop/RoseDevelopment/emsdk/node/12.18.1_64bit/bin"
export PATH=$PATH:"$HOME/doom/Desktop/RoseDevelopment/emsdk/upstream/emscripten"

The startPg command does not work before but does after inputting:

alias startPg='~/pgAdmin4/venv/bin/python ~/pgAdmin4/venv/lib/python3.8/site-packages/pgadmin4/pgAdmin4.py'

All of these commands work after I do source ~/.bashrc

I have commented out rvm. It still works before and after I do source ~/.bashrc I think this is because when installing rvm it puts you in an rvm group that gets access to the command I believe.

The echos above and below the emsdk (emcc) paths do not print out until I run source ~/.bashrc then they do run. I also put an echo at the very top of the file and it also doesn't run until I do the source of the file.

Here is what it looks like:

New one

Edit #4 I am sorry this is getting long but I was curious to see if this file might be causing problems:

.bash_profile

source "/home/doom/Desktop/RoseDevelopment/emsdk/emsdk_env.sh"

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

When I commented both the rvm line and the emsdk_env.sh line the echo's went away. rvm command still works the emcc command no longer does. I still have a no color output until I do source ~/.bashrc and then most of my other commands nvm/yarn/paper/startPg work again.

This makes me think somehow my .bashrc file is not being loaded in on a fresh session?

Here is a look:

doom@doom-MacBookPro:~$ rvm
# It works here
doom@doom-MacBookPro:~$ yarn
-bash: yarn: command not found
doom@doom-MacBookPro:~$ rvm list
#This works here
doom@doom-MacBookPro:~$ emcc
-bash: emcc: command not found
doom@doom-MacBookPro:~$ paper
-bash: paper: command not found
doom@doom-MacBookPro:~$ nvm
-bash: nvm: command not found
doom@doom-MacBookPro:~$ source ~/.bashrc 
am i here?
hello world

    Can you post your ~/.bashrc and your /etc/bashrc files? Do obscure anything sensitive etc.

  • This is puzzling - from the symptoms I thought the system bashrc had extra lines in it, and re-sourcing your personal .bashrc was updating the colour. But looking at those two files, its not clear where the prompt's colour change is happening. The EXPORT lines should not print anything, and they are before source "/etc/profile.d/rvm.sh" which might be relevant. I'm at a loss now, sorry.

    Try running each line one at a time, copy and paste them into an xterm/terminal window..

    my initial suspicion is also in the rvm.sh file. Maybe comment that out in .bashrc and see what happens. Another way of debugging is adding a bunch of echo in your .bashrc at different points, so you'll see if those messages are printed before or after each echo (make sure to put different message on each echo)

Alright I may have finally figured it out. Going from the comments below my question. By the way thank you @Criggie and @msb.

It appears I can even turn back on my run as command login shell in my terminal preferences if I follow what @user3584014 did as the second answer to this question: https://askubuntu.com/questions/161249/bashrc-not-executed-when-opening-new-terminal https://askubuntu.com/a/768359/1138077

Which is summed up pretty nicely:

In my case, simply the .bashrc loader lines were missing in .bash_profile

# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
    . "$HOME/.bashrc"
fi
I added it manually and it worked with my fresh login

This allowed all of my commands including emcc to work and to get my color back right from the start.

I still receive the emcc command echos from its being sourced in my

.bash_profile:
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
    . "$HOME/.bashrc"
fi

source "/home/doom/Desktop/RoseDevelopment/emsdk/emsdk_env.sh"

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

However that is not much of a problem as long as everything else works from the start as opening multiple terminals up for things and then always having to do source ~/.bashrc was the real pain.
