Ocaml 模块案例名称混淆

我更大的问题是:
您的第一个错误可能是因为您的操作系统不区分文件名中的大小写,但OCaml会:
$ ocamlobjinfo `ocamlfind query oUnit`/oUnit.cmi
File /mnt/home/jun/.opam/system/lib/oUnit/oUnit.cmi
Unit name: OUnit
Interfaces imported:
cb146e345f0b34fc8ad4b5afe69d1f20 OUnit
...
您可以看到该模块被称为“OUnit”,而不是“OUnit”
第二个错误显然是因为库尚未加载到REPL中。REPL知道函数的存在,但没有加载代码。如果加载库及其所依赖的库,则可以访问该库:

我通过将我的ocamlbuild
调用更改为使用-use-ocamlfind
解决了这个问题,这似乎解决了所有路径混乱的问题
我还卸载了所有OCaml模块,安装了OPAM,然后通过OPAM安装了OUnit和其他模块,并重新登录,这样我的环境就完美无缺了
现在适用于我的build命令是
这是由我更新的构建脚本生成的
