当我输入using Xpress它时，它会显示两个错误。一个是

LoadError: XPRESS cannot be loaded. Please run Pkg.build("Xpress")

另一个是

Failed to precompile Xpress [9e70acf3-d6c9-5be6-b5bd-4e2c73e3e054] to C:\Users\cys\.julia\compiled\v1.6\Xpress\jl_7C6D.tmp.

我试图解决它，Pkg.build("Xpress")但它告诉我

ERROR: Error building `Xpress`:
ERROR: LoadError: Unable to locate Xpress installation.
Please check your enviroment variable XPRESSDIR.
Note that Xpress must be obtained separately from fico.com.

使用 Xpress Pkg.build("Xpress")
