采坑
Cannot create a file when that file already exists.
通过 nvm install x.x.x 之后启用这个版本，例如：
$ nvm install 14.18.0 $ nvm use 14.18.0 exit status 1: Cannot create a file when that file already exists.点击复制复制失败已复制
问题产生的原因
安装 nvm 过程中，会要设置 nodejs 的快捷连接 symlink ， windows 默认是 C:\Program Files\nodejs 。
nvm 就是通过修改快捷链接来改变node的版本。
然而之前系统中已经安装了 nvm ，有残留，具体可以看此issue
解决办法
卸载 nvm ，删除 C:\Users\User Name\AppData\Roaming\nvm 文件夹，重新安装。

$ nvm use 14.18.0 exit status 1: Access is denied.点击复制复制失败已复制
产生原因
由于安装路径自定义到了E盘，然后 node 后采用 nvm use x.x.x 来激活版本失败。
解决办法
以管理员身份运行 CMD ，之后执行 nvm use x.x.x 命令即可。
