Question

我是npm和nodejs的新手。输出是什么意思？如何调试？

某些版本信息：

10:29:33 + echo ==========================+
10:29:33 ==========================+
10:29:33 + which node
10:29:33 /usr/bin/node
10:29:33 + echo ==========================+
10:29:33 ==========================+
10:29:33 + /usr/local/n/versions/node/5.5.0/bin/node --version
10:29:33 v5.5.0
10:29:33 + echo ==========================+
10:29:33 ==========================+
10:29:33 + node -v
10:29:33 v0.10.37
10:29:33 + echo ==========================+
10:29:33 ==========================+
10:29:33 + /usr/local/n/versions/node/5.5.0/bin/npm --version
10:29:33 3.3.12
10:29:33 + echo ==========================+
10:29:33 ==========================+

...

错误输出：

gulpfile.js的一部分：

 30 gulp.task( 'sass', () => {
 31   config.sass.targets.forEach( target => {
 32     gulp.src( target.src )
 33       .pipe( sass( config.sass.options ) )
 34       .pipe( gulp.dest( target.dest ) );
 35   });
 36 });

箭头功能（它们是es2015的一部分）默认在节点0.10-0.12中禁用，并在5.5中启用

您在节点0.10中出现了与不支持的箭头函数语法相关的错误。

简而言之，当您运行gulp时，就会运行node gulp。您表明which node给出了节点0.10的路径，因此gulp总是在它下面运行。

<强>解决方案

/usr/local/n/versions/node/5.5.0/bin/node $(which gulp)

gulp在Jenkins上失败了，但在我的VM上取得了成功
