Question

在Ubuntu 18.04英特尔系统上，我让Jupyter Lab顺利运行了Julia 1.0.4内核。我想添加1.3内核。我从官方下载站点下载了64位linux二进制文件。我运行了二进制文件，并给出了使用Pkg; Pkg.add（“ IJulia”）; Pkg.build（“ IJulia”）的命令，没有错误。

当我运行Jupyter Lab并选择1.0.4笔记本时，系统尝试预编译IJulia并出现以下错误：

内核1.3笔记本似乎运行正常。

关于如何解决此问题的任何想法？

Answer 1

可能您已将julia 1.0.4安装为32位。您可以通过启动julia并输入sizeof(Int)来进行检查。如果返回4，则为32位二进制。当您安装julia 1.3.0和IJulia时，它用64位的32位libzmq.so库覆盖了julia 1.0.4中无法使用的库。如果是这种情况，我建议您替换为用64位版本替换32位julia 1.0.4。

Answer 2

我已通过用1.0.5（这是长期支持内核）替换1.0.4内核来解决此问题。
