140You ran `/plugin install <plugin>@<name>` in a session, often from an install line someone sent you, and Claude Code reported that it has no marketplace by that name.
140You ran `/plugin install` in a session and Claude Code reported that it has no marketplace by that name. Two forms of the command reach this message:
141
142* **`/plugin install <plugin>@<name>`**: the install line, often one someone sent you, names a marketplace you haven't added. The rest of this entry covers finding and adding it.
143* **`/plugin install <source>` with a path, URL, or `owner/repo`**: this form reports the message instead of installing, even for a source you've already added. To install from a source in one command, see [Add a marketplace and install in one command](/docs/en/plugins/install#add-a-marketplace-and-install-in-one-command).
