node --harmony:没有这样的文件或目录

标签: node.js command-line-interface ecmascript-harmony

  

规格:Ubuntu 14.04 LTS服务器--- NodeJS 5.7.0 --- NPM 3.6.0

我正在使用启动命令运行自定义cli工具:#!/usr/bin/env node --harmony。在我的本地计算机上运行正常(也是v5.7.0),但在我的服务器上我得到了:

/usr/bin/env: node --harmony: No such file or directory

我的问题是:如何将harmony工具默认设为true?

我试过跑:

node --v8-options | grep -A1 harmony

this文章说它应显示true,但所有harmony工具似乎都已停用。

root@server:/home/iskore# node --v8-options | grep -A1 harmony

答案 0 :(得分:-1)

这篇文章应该指出你需要知道的所有方向:

What does `node --harmony` do?

但是:

在V8中将和声标志设为真

获得源代码后,打开deps / v8 / src / flag-definitions.h并查找第115行

将标志从false更改为true。

DEFINE_bool(和谐,真实,“启用所有和声功能”)

编译节点

./ configure&&制造&& make install
