pip install aaanalysis[pro] fails (zsh: no matches found)

[junkang812]

Hi, There is a small issue while trying to install aaanalysis[pro] using pip

When I ran:
pip install aaanalysis[pro]
the installation failed in zsh with the following error:
zsh: no matches found: aaanalysis[pro]

However it worked through quoting the package name
pip install "aaanalysis[pro]"

Installing the basic package (pip install aaanalysis) works fine

Issue: zsh No Matches Found for aaanalysis[pro]

This issue occurs because zsh treats square brackets ([ ]) as globbing characters (used for pattern matching). Since aaanalysis[pro] isn't a valid file pattern, zsh throws an error.

Solution

Use quotes to prevent zsh from interpreting the brackets:

pip install "aaanalysis[pro]"

or escape the brackets:

pip install aaanalysis\[pro\]

Why does it work in bash?

In bash, square brackets are not treated as special characters unless they match a file pattern. Therefore, the following command works without issues:

pip install aaanalysis[pro]
