电池的这个编译错误真的让我很困惑。我应该如何修复错误？

Answer 1

你知道OPAM吗？

$ opam install batteries

它将自动安装所有依赖项。

[编辑] 如何安装opam：

$ git clone https://github.com/OCamlPro/opam
$ ./configure # (or ./configure --prefix=$HOME if you want to install under your $HOME)
$ make
$ make install
$ opam init
$ eval `opam config -env`

Answer 2

你可以执行脚本：

/home/fanzhihang/batteries-1.4.1/_build/sanitize.sh

这将删除 OCamlbuild 认为不应该在此处的文件（即 .annot、.cmo 和错误所涉及的 .cmi）。
