process.versions

版本历史
版本变更
v9.0.0

属性 v8 现在包含 Node.js 特定的后缀。

v4.2.0

现在支持 icu 属性。

v0.2.0

新增于: v0.2.0

process.versions 属性返回对象，其中列出了 Node.js 的版本字符串及其依赖项。 process.versions.modules 表示当前的 ABI 版本，每当 C++ API 更改时都会增加。 Node.js 将拒绝加载针对不同模块 ABI 版本编译的模块。

console.log(process.versions);

将生成类似于以下内容的对象：

{ node: '11.13.0',
  v8: '7.0.276.38-node.18',
  uv: '1.27.0',
  zlib: '1.2.11',
  brotli: '1.0.7',
  ares: '1.15.0',
  modules: '67',
  nghttp2: '1.34.0',
  napi: '4',
  llhttp: '1.1.1',
  openssl: '1.1.1b',
  cldr: '34.0',
  icu: '63.1',
  tz: '2018e',
  unicode: '11.0' }
History
VersionChanges
v9.0.0

The v8 property now includes a Node.js specific suffix.

v4.2.0

The icu property is now supported.

v0.2.0

Added in: v0.2.0

The process.versions property returns an object listing the version strings of Node.js and its dependencies. process.versions.modules indicates the current ABI version, which is increased whenever a C++ API changes. Node.js will refuse to load modules that were compiled against a different module ABI version.

console.log(process.versions);

Will generate an object similar to:

{ node: '11.13.0',
  v8: '7.0.276.38-node.18',
  uv: '1.27.0',
  zlib: '1.2.11',
  brotli: '1.0.7',
  ares: '1.15.0',
  modules: '67',
  nghttp2: '1.34.0',
  napi: '4',
  llhttp: '1.1.1',
  openssl: '1.1.1b',
  cldr: '34.0',
  icu: '63.1',
  tz: '2018e',
  unicode: '11.0' }
