用nvm安装节点失败吗？

Question

我在mac上，我用curl安装了nvm，工作得很好。我是“nvm安装节点”，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.

我试着运行'nvm use --delete-prefix v7.10.0命令，但它似乎没有任何效果。

怎么一回事？

Answer 1

从prefix中删除这个npm prefix变量应该会有帮助。
