當我運行使用JLD我得到以下警告：朱莉婭使用JLD：警告：模塊HDF5 UUID不匹配緩存文件
INFO: Recompiling stale cache file C:\Julia\PkgDir\lib\v0.4\JLD.ji for module JLD.
WARNING: Module HDF5 uuid did not match cache file
This is likely because module HDF5 does not support precompilation but is imported by a module that does.
WARNING: deserialization checks failed while attempting to load cache from C:\Julia\PkgDir\lib\v0.4\JLD.ji
INFO: Precompiling module JLD...

WARNING: Module HDF5 uuid did not match cache file

__precompile__(true) but require failed to create a precompiled cache file
如果我再運行說：
A=ones(40)
save("c:\\OneDrive\\Model\\myfile.jld", "A", A)
我得到錯誤：
UndefVarError: save not defined in include_string at loading.jl:288 in eval at

我使用的是Atom 1.8.0和Julia 0.4.7。就我所知，我使用JLD是唯一的pkg，它允許我將變量寫入文件並保留其所有屬性。
