在 Julia 中构建 CPLEX 失败

Question

我正在尝试在计算机集群上的 Julia 中安装 CPLEX。当我执行 Pkg.build("CPLEX") 时出现以下错误。看来我没有走对路。我知道如何在我的本地计算机上修复它，但谁能告诉我如何在计算机集群上修复它？还是其他问题？

供您参考，

CPLEX 版本：12.10-GCCcore-8.3.0，朱莉娅版本：1.7.1.

非常感谢。

The versions of CPLEX supported by CPLEX.jl are:

* 12.10
* 20.1

You must download and install one of these versions separately.

You should set the `CPLEX_STUDIO_BINARIES` environment variable to point to
the install location then try again. For example (updating the path to the
correct location):


ENV["CPLEX_STUDIO_BINARIES"] = "/opt/CPLEX_Studio201/cplex/bin/x86-64_linux/"
import Pkg
Pkg.add("CPLEX")
Pkg.build("CPLEX")


See the CPLEX.jl README at https://github.com/jump-dev/CPLEX.jl for further
instructions.

Answer 1

（在评论讨论中找到的解决方案，添加为答案以获得更好的可见性。）

如错误消息所示，您必须将 ENV["CPLEX_STUDIO_BINARIES"] 值设置为包含 cplex 的目录。您可以通过运行ning which cplex | xargs dirname（或简单地 which cplex 并自己从结果中删除最后的 cplex）找到它。

如果您将 CPLEX_STUDIO_BINARIES 设置为该路径，您可以再次运行 Pkg.build("CPLEX") 让 CPLEX.jl 从路径中获取二进制文件。
