I can not uninstall the gitbook CLI version: 2.3.2 with

npm uninstall gitbook-cli -g ,

and then run

npm install gitbook-cli@2.1.2 --global

nothing happened.

I sloved it by

cd ~/.gitbook/versions/3.2.3/node_modules/npm/node_modules/
vim package.json 

change the version of graceful-fs to 4.2.0,and then

npm install

after that, everything is ok.

what's more, my node version is 12.22 , if node version is 14 up, that may cause other problems.
