npm cache clean
npm ERR! As of npm@5, the npm cache self-heals from corruption issues
npm ERR! by treating integrity mismatches as cache misses. As a result,
npm ERR! data extracted from the cache is guaranteed to be valid. If you
npm ERR! want to make sure everything is consistent, use `npm cache verify`npm ERR! instead. Deleting the cache can only makenpm go slower, and is
npm ERR! not likely to correct any problems you may be encountering!npm ERR!npm ERR! On the other hand, if you're debugging an issue with the installer,
npm ERR! or race conditions that depend on the timing of writing to an empty
npm ERR! cache, you can use `npm install --cache /tmp/empty-cache` to use a
npm ERR! temporary cache instead of nuking the actual one.
npm ERR!
npm ERR! If you're sure you want to delete the entire cache, rerun this commandnpm ERR! with --force.npm ERR! A complete log of this run can be found in:

npm i 和 npm install 的區別
npm i 安裝的模塊及依賴，使用npm uninstall是沒有辦法刪除的，必須使用npm uninstall i才可以刪除。
