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

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
