我看到别人有similar problems，但我还没有找到解决方案。

安装步骤

我按照以下说明执行了以下操作，以便在Ubuntu/WSL2上安装nvm和node：

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

mkdir ~/.npm-global

npm config set prefix ~/.npm-global

cat >> ~/.bashrc <<EOF
export PATH="$HOME/.npm-global/bin:$PATH"
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" 1>&2  # Loads nvm
EOF

nvm install node

$ which npm
/home/mslinn/.nvm/versions/node/v17.6.0/bin/npm

$ cat ~/.npmrc
fund=false
prefix=/home/mslinn/.npm-global

现在的问题

$ source ~/.bashrc
Your user’s .npmrc file (${HOME}/.npmrc)
has a `globalconfig` and/or a `prefix` setting, which are incompatible with nvm.
Run `nvm use --delete-prefix v17.6.0 --silent` to unset it.

删除prefix设置会忽略手动更改的npm默认目录。
