弹性转储安装的问题:异步_loop意外标识符错误

Question

安装elasticdump会引发一系列警告，如下所示

$ npm install -g elasticdump
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated har-validator@5.1.5: this library is no longer supported

+ elasticdump@6.56.0

之后，可执行文件在调用时总是抛出以下错误

$ elasticdump --version   
/Users/ebeisaac/.npm-packages/lib/node_modules/elasticdump/lib/processor.js:40
  async _loop (limit, offset, totalWrites) {
        ^^^^^

我甚至试着安装npm，就像在本网站中一样。结果仍然一样。

如何解决这一问题并使elasticdump工作？

从日志中：

npm WARN notsup Unsupported engine for p-timeout@3.2.0: wanted: {"node":">=8"} (current: {"node":"6.13.1","npm":"6.14.9"})

您使用的是node.js版本6.x，但它不支持节点v6。您需要升级到v8或更高版本。

您还可以参考这和这 Github问题。

问题 in conda阻止它在Mac中安装最新的nodejs版本。在这种情况下，解决方案将是conda卸载版本 就像这样，并使用一种替代方式，如自制或从官方网站中提取pkg。

注意:不要同时安装conda和自制版本的，否则即使执行npm也会引发问题中显示的相同错误。
