<p data-path-to-node="0">That <code data-path-to-node="0" data-index-in-node="5">externally-managed-environment</code> error is actually a built-in safety feature in newer versions of Linux Mint (and Ubuntu/Debian).

<p data-path-to-node="1">To fix this, you just need to install <code data-path-to-node="1" data-index-in-node="38">pipx</code> using Linux Mint's system package manager (<code data-path-to-node="1" data-index-in-node="86">apt</code>) instead of <code data-path-to-node="1" data-index-in-node="102">pip</code>.</p>
