npm ERR! code EINTEGRITY问题解决方案

ng new auction 的时候发生错误

npm ERR! code EINTEGRITY
npm ERR! sha1-HL9h0F1rliaSROtqO85L2RTg8Aw= integrity checksum failed when using
sha1: wanted sha1-HL9h0F1rliaSROtqO85L2RTg8Aw= but got sha1-tar5Z+PWK36XC8GUqx0S
Bg9vLKk=. (1991280 bytes)

出现此种问题的原因是npm的版本过低

运行npm install -g npm后

再运行ng new auction
