Unable to find plugin for. zshrc configuration

[V-zhangyunxiang]

I installed zsh autosuggestions through brew, but after executing source~/. zshrc, I was prompted [oh-my-zsh] plugin 'zsh-autosuggestions' not found，Then I moved the zsh autosuggestions in the brew directory to the~/. oh my zsh/custom/plugins/path and executed source~/. zshrc again, but it still did not work
