Conda command not found

Question

I've installed Miniconda and have added the environment variable export PATH="/home/username/miniconda3/bin:$PATH" to my .bashrc and .bash_profile but still can't run any conda commands in my terminal.

Am I missing another step in my setup? I'm using zsh by the way.

Solution 1

If you're using zsh and it has not been set up to read .bashrc, you need to add the Miniconda directory to the zsh shell PATH environment variable. Add this to your .zshrc:

export PATH="/home/username/miniconda/bin:$PATH"

Make sure to replace /home/username/miniconda with your actual path.

Save, exit the terminal and then reopen the terminal. conda command should work.

Solution 2

If you have the PATH in your .bashrc file and are still getting

conda: command not found

Your terminal might not be looking for the bash file. Type bash in the terminal to ensure you are in bash and then try: conda --version

Solution 3

Maybe you need to execute "source ~/.bashrc"

Solution 4

For those experiencing issues after upgrading to MacOS Catalina.

Short version:

# 1a) Use tool: conda-prefix-replacement - 
# Restores: Desktop -> Relocated Items -> Security -> anaconda3
curl -L https://repo.anaconda.com/pkgs/misc/cpr-exec/cpr-0.1.1-osx-64.exe -o cpr && chmod +x cpr
./cpr rehome ~/anaconda3
# or if fails
#./cpr rehome ~/anaconda3 --old-prefix /Anaconda3
source ~/anaconda3/bin/activate

# 1b) Alternatively - reintall anaconda - 
# brew cask install anaconda

# 2) conda init
conda init zsh
# or
# conda init

Sometimes, if you don't restart your terminal after you have installed anaconda also, it gives this error.

Close your terminal window and restart it.

It worked for me now!

Instead of exiting and reopening, Using source ~/.zshrc will do

I tried this, but I still get an error when trying to install stuff CondaIOError: Missing write permissions in: /anaconda

It works! But the path has a slight difference. export PATH="/Users/victorzhang/anaconda2/bin:$PATH", the path beginning is /Users/, instead of /home/ still thank you @olivrg

[patti_jane]

thanks for this! But what is the reason we have to type bash?

[Kenan]

im not 100% sure but I think it's to let your command prompt read the bashrc file

For those who don't know: copy the command in the .zshrc file that will be located in your /User/<yourusername>/ directory.

[Vyacheslav Tsivina]

Yes, the start script for conda was added inside your .bashrc file during installation, so you need to start bash shell to start the conda

My binary was in condabin at in /usr/local/anaconda3--it's 2021 and I'm on a Mac. I added condabin to the path in .zshrc at /User/<yourusername>/ and it worked.

On ubuntu i needed to refer to home so i used: export PATH="~/anaconda3/bin":$PATH and it worked

[Karan Sharma]

Can you explain what does this command actually do? Thanks!

[Vinay Verma]

nano ~/.bashrc - then in the end add export PATH="/home/username/miniconda3/bin:$PATH" Make check if its miniconda or miniconda3 source ~./.bashrc

[frmbelz]

Also instead of close/open terminal, could source ~/.bashrc OR . ~/.barshrc if bash is a shell you are using (to see your shell echo $0)

[frmbelz]

echo $0 to see what shell if it is .bashrc or .zshrc OR ls -ld ~/.* to see which one is already there.

[Gulzar]

where is .zshrc? Is it a mac thing?

[olivrg]

.zshrc is the configuration file. You can open it with your text editor using this command: nano ~/.zshrc

@KaranSharma I believe it resets the environment variables for your profile. If you recently installed Anaconda, that file was edited by the installer with the new env variables, but have not been loaded for conda or other utilities. I might be wrong, I'm new to this whole thing.
