Can't find mmdc after upgrading to node.js v12.18.3

[VincentTam]

Description

I installed this package with its dependences globally in node.js v10.x last summer.

After having upgraded to node.js v12.18.3, I got the same error as shown in the title of #52.

$ mermaid-filter -v

$ mmdc -V

In the linked issue, you've asked me to install the tool in node_modules.

• global: I ran npm update -g to update all globally installed packages under ~/.nvm/versions/node/v12.18.3/.
• local: I ran npm i mermaid-filter to install this package (with its dependencies) under ./node_modules/.

package local install

after package local install, this package still can't find mmdc
