使用 nvm 安装节点失败?

Installing node with nvm fails?

我在 mac 上,我使用 curl 安装了 nvm,工作正常。我'nvm install node',我得到:

Downloading and installing node v7.10.0...
Downloading https://nodejs.org/dist/v7.10.0/node-v7.10.0-darwin-x64.tar.xz...

    at writeLogFile (/myhomedir/.nvm/versions/node/v7.10.0/lib/node_modules/npm/lib/utils/error-handler.js:205:32)

nvm is not compatible with the npm config "prefix" option: currently set to ""
Run `nvm use --delete-prefix v7.10.0` to unset it.

我尝试了 运行 'nvm use --delete-prefix v7.10.0 命令,但它似乎没有效果..

这是怎么回事?

~/.npmrc 中删除这个 npm prefix 变量应该会有帮助。
