Mac bower install bootstrap bug resolved

Recently, I have been using vue and vue-based UI frameworks, such as Element. I haven't used BootStrap for some years. I don't know why tonight I suddenly want to install BootStrap to my own small project. When using bower to install, the following error has been reported:
/ usr/local/lib/node_modules/bower/lib/node_modules/configstore/index.js:54
throw err;
^
Error: EACCES: permission denied, open '/Users/XiaoQiang/.config/configstore/bower-github.json'

Baidu has checked a lot of methods and found that it is useless. The most common statement is this:

sudo bower install –allow-root
sudo bower install

The pro test is not available, I feel that the answers are all copied and pasted, and the reference value is not high.

Finally found a solution on github, which is available for personal testing.

sudo chown -R$USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config
