i have already tried these options

• npm cache clean --force
• reinstalling npm and node
• switching different version of npm

回答1:

the error npm ERR! shasum check failed and npm ERR! Unexpected end of JSON input while parsing near'....' ,   will be solved by switching npm reigistry from the list of given npm registry.

List of Npm registry:

• https://registry.npmjs.org/ (Dfault One)
• http://r.cnpmjs.org/
• https://registry.npm.taobao.org/
• https://registry.nodejitsu.com/
• http://registry.mirror.cqupt.edu.cn
• https://skimdb.npmjs.com/registry
• https://npm.open-registry.dev/ (https://open-registry.dev)

To switch just type

npm config set registry "https://registry.npmjs.com/"

Replace the registry url with the above urls check which one works for you.

After That:

npm cache clear --force

npm cache verify

now error will be solved.
