【已解决】IJulia的安装使用问题

综合讨论区 库的安装及使用

麻烦大家问个有关IJulia的问题：

一、Julia版本：

julia> versioninfo()
Julia Version 1.0.2
Commit d789231e99 (2018-11-08 20:11 UTC)
Platform Info:
  OS: Windows (x86_64-w64-mingw32)
  CPU: Intel(R) Core(TM) i5-3337U CPU @ 1.80GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-6.0.0 (ORCJIT, ivybridge)

二、Pkg.add("IJulia")运行成功后，using IJulia出错，显示如下：

julia> using IJulia
[ Info: Precompiling IJulia [7073ff75-c697-5162-941a-fcdaad2a7d2a]

三、继续运行Pkg.build("IJulia")，报错如下：

请问这个问题该如何解决呢 :sweat_smile:

顺便我想问一下，Julia版本更新以后，我卸载掉旧版本，安装新版本后，jupyter notebook的kernel就没有julia的选项了，我看jupyter官网上说要重新执行Pkg.build("IJulia")，但是还是会报错，和上面显示的问题一样，这是为什么呢 :joy:

2

管理员权限试试吧

3

我在管理员权限下试过了，报错是一样的 :disappointed_relieved:

4

运行Pkg.build("IJulia")后，报错内容中有：

[WinError 5] 拒绝访问。: 'C:\\Users\\huoze\\AppData\\Roaming\\jupyter\\kernels\\julia-1.0\\logo-32x32.png'

只需要把这个路径下的那两个logo.png删除就行了 :joy:，具体原因的话不太清楚

5

我也是出这个错，但是我都是到这个目录里把这俩图片属性中的只读的√去掉，然后就没问题了。
