如何从 Julia 的当前目录中删除文件？

file.remove()有没有像R中那样的直接函数？

就在这里rm。请参阅 Julia in-REPL 帮助（您可以通过按 访问该帮助?）：

If force=true is passed, a non-existing path is not treated as error. If recursive=true is passed and the path is a directory, then all contents\n  are removed recursively.\n\n  Examples\n  \xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\xe2\x89\xa1\n\n  julia> mkpath("my/test/dir");\n\n  julia> rm("my", recursive=true)\n\n  julia> rm("this_file_does_not_exist", force=true)\n\n  julia> rm("this_file_does_not_exist")\n  ERROR: IOError: unlink: no such file or directory (ENOENT)\n  Stacktrace:\n  [...]\n

所以你可以这样做rm(filename)。
