Describe the fix or the content request.
Qiskit SDK 1.4 or later, with visualization support (pip install 'qiskit[visualization]')
Running that command with the single quotes doesn't work for me. I need to use pip install'qiskit[visualization]
For new content requests - if the request is accepted, do you want to write the content?
I will write (or already have written) a draft of the proposed content
@beckykd we ended up deciding to either use tabs to specify the pip install command for windows vs non-windows machines. But if it ends up being too busy, maybe just write a note in parentheses.
do we want to address this or leave it as is? Maybe we should just name the package requirements without installation instructions
Just adding a note here for those who find this GitHub Issue via googling: the Qiskit installation guide at time of writing has some issues with the instruction to install the visualisation support for users on Apple's OS X operating system.
Problem & workaround
This is what is stated:
pip install qiskit[visualization]
If you get a zsh: no matches found: qiskit[visualization] message, try this instead:
pip install "qiskit[visualization]"
Reason
The zsh shell (the default on modern macOS) uses square brackets for "globbing," which is a way to match filenames. For example, ls file[123].txt would find file1.txt, file2.txt, etc.
When you type pip install qiskit[visualization], zsh looks for files in your current directory that match that pattern. When it finds none, it gives you the error: zsh: no matches found.
Wrapping the name in quotes prevents this by telling the shell, "Hey friend, don't try to be clever with this part, just pass it along as is."
