I've installed the expo CLI and am trying to use expo init to start a project. When I do, this is returned:
bash: expo: command not found
I saw that this required updating the .bash_profile with export PATH=$PATH:~/node_modules.
However, apparently Mac OS Catalina switched from .bash_profile to zprofile or zshrc. Advice online said one should instead add PATH=$PATH:~/node_modules to the end of zshrc.
I tried doing this, but it says the file is locked. When I try to edit it, this pops up:
You don’t own the file “zshrc” and don’t have permission to write to it.
Any ideas how to move forward to fix this?
P.S. I installed anaconda a while ago and saw that the .bash_profile had this:
# added by Anaconda3 5.0.1 installer
export PATH="~/anaconda3/bin:$PATH"
# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
PATH="~/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH
This might be a problem? I updated the file with the new path, but expo still was not recognized. That's when I found out Catalina switched to zprofile & zshrc.
I've been stuck on this for a long time and tried a bunch of things -- any advice would be greatly appreciated!
You're not using ZSH, if you were, you'd get zsh: command not found: expo. You could either switch to using zsh using chsh or keep using Bash.
Then you should add the PATH modifications (export PATH ...) to the appropriate shell config file .bash_profile or .zshenv, by running sudo vim ~/.bash_profile or sudo vim ~/.zshenv, or if you have VSCode, its probably easier with sudo code ~/.zshrc

Background:
Dear Stackoverflow community. I recently switched from Windows to MacOS and am at a loss how to configure environment variables. Many of the previous questions asked here are about bash instead of zsh.
Goal:
I am trying to install an npm package globally. For instance:
npm install -g vercel
or any other package, and use it in my Visual Studio Code terminal (also zsh). If I want to deploy code I have to use 'npx vercel deploy' every time. I want to be able to use "vercel deploy" but instead I get:
zsh: command not found: vercel
What I tried so far:
Installing the package in zsh and visual studio code terminals (didn't work)
Setting the path equal on both VS and terminal: export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
I learned that you need to add environment variabels to a .zshrc file. I don't seem to have a zshrc file. When I do:
sudo ~/.zshrc
Password: XXXXXX
sudo: /Users/vincent/.zshrc: command not found
I am getting another error.
I read in the zsh man file that you should use $HOME/.zshrc instead. Again I am getting the same errors:
vincent#Vincents-MacBook-Air-2 ~ % $HOME/.zshrc
zsh: permission denied: /Users/vincent/.zshrc
vincent#Vincents-MacBook-Air-2 ~ % sudo $HOME/.zshrc
sudo: /Users/vincent/.zshrc: command not found
Update 1:
#slebetman Thank you for your explanation. When I open the terminal I go to home via "cd $HOME" which puts me in in the home directory. However there is no way for me to create a .zshrc file in that directory. Neither via touch or vs code. I am getting the following error: "Unable to write file '/home/.zshrc' (Unknown (FileSystemError): Error: ENOTSUP: operation not supported on socket, open '/home/.zshrc')"
Update 2:
I did manage to find the .zshrc file in visual studio code under /etc. I hope this will work. I was able to overwrite the file with Sudo and add environment variables to it.
Add this to the file .zshrc file under /etc and force overwrite it:
export vercel=/Users/vincent/.npm-global/bin/vercel
Screenshots below for those who will try in the future:
Image with .zshrc file layout
Final remarks:
I don't understand how it is so difficult to add environment variables on Mac while everything else is so easy.
I have read many different questions on stackoverflow, and I can't seem to solve it. Also since I am a newbie I am not allowed to comment on there so I post here in the hope that anyone can help me :)
Best,
Vincent
Note that when you do:
npx vercel deploy
Npm will execute vercel for you without installing it. It does that by temporarily downloading vercel. If you want to run vercel directly without using npx then simply don't use npx. Install it instead:
npm install -g vercel
The -g flag installs the module globally and if the module has a CLI it will be available globally as well (note that depending on your setup you may need admin/sudo privileges to use the -g flag). Now you can run vercel by simply typing:
vercel deploy
This works in all operating systems supported by node.js and npm. That means you can even do this in Windows. In fact I use npm to distribute my tools in a simple cross-platform way so I don't have to support multiple package managers like chocolatey (Windows), homebrew (Mac OS), deb (Debian based distros), rpm (Redhat based distros) etc. (npm does not require your software to be written in node.js - I have published packages on npm written in tcl and bash).
I am using this guideline to install solartherm: https://github.com/SolarTherm/SolarTherm/wiki/Running-SolarTherm-on-Windows-%28MSYS2%29
I reach the point where I need to install Dakota and I get this error:
-bash: unzip: command not found
cp: cannot stat 'dakota-6.14.0.Windows.x64/*': No such file or director
The first error message there is telling you that unzip does not exist. That command comes from a file (/usr/bin/unzip.exe) that is provided by an MSYS2 package named unzip. So you need to install that package by running pacman -S unzip and then try again.
Note that the wiki page you linked to already told you to install the unzip package so I recommend that you go back to the beginning of the instructions and double check all of them to make sure you are on the right track. Pay attention to any error messages you receive along the way.
Good evening,
I tried installing sails, yo, gulp & bower via the usual methods of npm i -g yo gulp bower etc but each time I open the terminal to run the command I always get the -bash: sails: command not found error.
I listed all my folders at the root of my folder and found the following:
The contents of the .npm-global/bin/ is actually all the packages I'm trying to use at the command line.
I decided to manual add the bin folder to the .bash_profile so it's contents was the following:
# Setting PATH for Python 3.7
# The original version is saved in su
export PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH="/.npm-global/bin:${PATH}"
but that didn't work either.
Here's where I think the problem first arose - I think that the python install overrode all the previous paths in the file (or moved them somewhere perhaps?) so that all previous terminal commands now don't work.
The usual global install for node packages (/usr/local/lib/node_modules/npm/bin) contains the following:
What am I misunderstanding here & how can I fix this?
Like a lot of people I am also having issues with Yeoman.
Error -bash: yo: command not found in OSx.
I tried adding export PATH=/usr/local/share/npm/bin:$PATH on my .bash_profile as suggested by some folks and still same error.
I've lost 2 hours of my productivity trying to fix Yeoman bugs and still nothing.
Does anyone know any good solution that fixes the -bash: yo: command not found ?
I found that for recent versions of npm, all node packages are installed in the ~/npm/bin/ directory.
So add those lines to your $PATH in the .profile file :
export PATH=$PATH:~/npm/bin
Then do :
source ~/.profile
yo -v
Finally found a solution for this.
First I had to uninstall and install yo again:
npm remove -g yo
npm install -g yo
I also added a symlink to the bash_profile to make yo work. The following line: PATH=${PATH}:~/.node/bin After that restart the prompt for the change to take action.
Please check this for more references: Why are my Yeoman generators installing in the wrong place?
try to add an symbolic-link (ln -s) into the /sbin -directory.
like:
ln -s /sbin/ /usr/local/share/npm/bin/yo
This also seems to work :)
sudo `yo angular2-ts [appname]`
where [appname] is the name of your app (without the []) :)
just give access for the user to read write execute in the folder webapp
sudo chmod 777 webapp
cd webapp
yo angular [appname]

Please help
P.S. I am on Mac Os

It is likely your nodeJS npm/bin folder that is not included in your PATH.
Can you check your PATH variable?
Node NPM package bin files are all symlinked in the same ./bin folder. If you installed NodeJS using Homebrew (brew install node), it should be /usr/local/share/npm/bin.
You can echo your current path using:
echo $PATH
If the folder above does not appear in the list, check your .bashrc or .bash_profile files and fix any problem.
A fix that is likely to work is to add the following line in ~/.bash_profile
PATH=$PATH:/usr/local/share/npm/bin
