将文本从文件转换为javascript对象

Question

我正在尝试读取文本文件，并使用Node JS将其转换为javascript对象。我的文件如下所示：

Package: libseccomp2
Depends: libc6 (>= 2.14)
Description: high level interface to Linux seccomp filter
 This library provides a high level interface to constructing, analyzing
 and installing seccomp filters via a BPF passed to the Linux Kernel's
 prctl() syscall.


Package: libperl5.26
Depends: libbz2-1.0, libc6 (>= 2.23), libdb5.3, libgdbm-compat4, libgdbm5 (>= 1.12), zlib1g (>= 1:1.2.2.3), perl-modules-5.26 (>= 5.26.1-6ubuntu0.3)
Description: shared Perl library
 This package contains the shared Perl library, used by applications
 which embed a Perl interpreter.
 .
 It also contains the architecture-dependent parts of the standard
 library (and depends on perl-modules-5.26 which contains the
 architecture-independent parts).

我想这样输出：

[{
Package: "libseccomp2",
Depends: ["libc6"]
Description: "high level interface to Linux seccomp filter
 This library provides a high level interface to constructing, analyzing
 and installing seccomp filters via a BPF passed to the Linux Kernel's
 prctl() syscall."
},
{
Package: "libperl5.26",
Depends: ["libbz2-1.0", "libc6"]
Description: "high level interface to Linux seccomp filter
 This library provides a high level interface to constructing, analyzing
 and installing seccomp filters via a BPF passed to the Linux Kernel's
 prctl() syscall."
}]

这是我到目前为止所拥有的，但是一直在给我错误。预先感谢您的帮助

fs.readFile('file.txt', "utf8", (err, data) => {
  if (err) {
    console.error(err)
    return
  }
  let obj = {};
  let line = data.toString().split("\n");
  for (let i = 0; i<line.length; i++) {
      let newLine = line[i].split(":");

      obj[newLine[0]] = newLine[1].split(" ");
  }
  console.log(obj);

})

您的源文件看起来像是从YAML文件派生的。如果格式正确，则可以使用“ yaml”之类的npm库将文件直接解析为JS对象。

格式正确的YAML文件如下：

-
 Package: libseccomp2
 Depends: libc6 (>= 2.14)
 Description: high level interface to Linux seccomp filter
  This library provides a high level interface to constructing, analyzing and installing seccomp filters via a BPF passed to the Linux Kernel's prctl() syscall.

-
 Package: libperl5.26
 Depends: libbz2-1.0, libc6 (>= 2.23), libdb5.3, libgdbm-compat4, libgdbm5 (>= 1.12), zlib1g (>= 1:1.2.2.3), perl-modules-5.26 (>= 5.26.1-6ubuntu0.3)
 Description: shared Perl library
  This package contains the shared Perl library, used by applications
  which embed a Perl interpreter.
  .
  It also contains the architecture-dependent parts of the standard
  library (and depends on perl-modules-5.26 which contains the
  architecture-independent parts).

我会先检查您的源文本文件是否可以生成为正确的YAML，或者如果您被当前文本文件所困扰，请尝试使用YAML validator将其编辑为正确的YAML。
