# 原因
似乎是npm判断机制有关
# 解决
解决办法是把原有相关npm的文件和文件夹全部重命名，然后再用重命名后的npm安装新的npm
进入node目录，重命名如下文件或文件夹：npm、npm.cmd、npx、npx.cmd、node_modules\npm，全部加上-old
然后进入重命名后的node_modules\npm-old\bin\
执行：node npm-cli.js i -g npm@latest
即可安装成功
命令行脚本
move npm npm-old
move npm.cmd npm-old.cmd
move npx npx-old
move npx.cmd npx-old.cmd
cd node_modules\
move npm npm-old
cd npm-old\bin
node npm-cli.js i -g npm@latest --force
