在jupyter notebook中是否也可以像python那样使用呢？答案是可以的。现在来记录一下配置步骤。

使用EvCxR作为jupyter notebook内核

安装

安装jupyter notebook或者jupyter lab
安装CMake，在安装EvCxR编译时会使用到。

安装EvCxR

1 2	cargo install evcxr_jupyter evcxr_jupyter --install

问题

安装过程中，原来rust选择的是gnu的工具链编译，但在编译libzmq时会报错，

D:\PROGRA~1\MINGW-~1\X86_64~1.0-P\mingw64\bin\G__~1.EXE   -std=gnu++11 -Wno-tautological-constant-compare  -o CMakeFiles\cmTC_57766.dir\CheckSymbolExists.cxx.obj -c E:\Tmp\libzmq-4.3.3\build\CMakeFiles\CMakeTmp\CheckSymbolExists.cxx

  (void)argv;
#ifndef strlcpy
  return ((int*)(&strlcpy))[argc];
#else
  (void)argc;
  return 0;
#endif
}

尝试手动编译libzmq, 但无论4.3.3或4.3.2版本都无法成功。具体原因从issue里也没有太多参考意义。后来从EvCxR issue 53中得到些启发，将rust的工具链换回msvc工具链。重新安装EvCxR，成功。
