在 NixOS 中，如何安装最新的 Jupyterlab？

我尝试运行pypi2nix -V 3 -e jupyterlab==1.0.0，但失败并显示“无法构建 ipykernel”。

还有其他方法可以安装 1.0.X 版本的 jupyterlab 吗？

编辑：我越来越接近了。这是我正在运行的 jupyterlab.nix nix-shell jupyterlab.nix：

with import <nixpkgs> {};

( let
    my_jupyterlab = python37.pkgs.buildPythonPackage rec {
      pname = "jupyterlab";
      version = "1.0.4";

      src = python37.pkgs.fetchPypi {
        inherit pname version;
        sha256 = "0vhdbzrphirl3x37d4zh0gaxhs6f7wj0i30wy4878yjkmlr219rj";
      };

      doCheck = false;
    };

  in python37.withPackages (ps: [ps.jupyter ps.tornado my_jupyterlab])
).env

但这无法建立，说明了龙卷风的情况。

在这里你可以找到一个合适的模板首先：

# default37.nix
# start with
#   nix-shell default37.nix
# or
#   nix-shell default37.nix -I nixpkgs=/home/isto/nixpkgs-unstable/
let 
  pkgs = import <nixpkgs> {};
  newpkgs = import pkgs.path { overlays = [ (pkgsself: pkgssuper: {
    python37 = let
      packageOverrides = self: super: {
            openpyxl = openpyxl2;
        # numpy = super.numpy_1_10;
      };
    in pkgssuper.python37.override {inherit packageOverrides;};
  } ) ]; };
