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


我正在使用以下命令运行自定义cli工具:#!/usr/bin/env node --harmony。在我的本地计算机(也可以是v5.7.0)上正常工作,但是在我的服务器上却得到:

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


我的问题是:如何将harmony工具的默认设置设为true?

我试过跑步:

node --v8-options | grep -A1 harmony


this文章说应该显示true,但是所有harmony工具似乎都被禁用。

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

先感谢您!

最佳答案

这篇文章应该为您指明所有需要了解的方向:

What does `node --harmony` do?

但是也:

在V8中将和声标志设置为true

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,正确,“启用所有和声功能”)

编译节点

./configure && make &&进行安装

关于node.js - Node --harmony:没有此类文件或目录,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/35725474/
