有没有办法在 NixOS 上安装 NPM 命令行工具？
[root@ip-xxx-xxx-0-27:~/teros/ntrs-cli]# sudo npm i -g typescript
npm WARN checkPermissions Missing write access to /nix/store/rhikjv5vlpa6vq4qkrszinwsaz1mda7p-nodejs-8.15.1/lib/node_modules

我假设因为它是只读的，因为我确实运行了：
chown -R `whoami` nix/store/rhikjv5vlpa6vq4qkrszinwsaz1mda7p-nodejs-8.15.1
顺便说一句，如果有人知道如何在 nixos 上安装 Node.js 版本 11 或 12，那就太好了。
