Question

****我正在开发一个Node.Js项目，该项目需要Python才能使应用程序正常运行。从我的Node Project目录运行命令“npm install”后，该项目抛出了一个错误，起初看起来很容易修复。 “无法找到Python可执行文件。”在以不同的方式设置Python环境路径3，并从我的项目路径成功访问我的python解释器后，它仍然抛出此错误。但我可以在命令行中输入“python”并拉出解释器。关于ELifecycle这个东西还有另外一个错误，即使在谷歌搜索和搜索StackOverflow后我也无能为力。这是我命令行的输出代码作为参考。此外，我已经编辑了不同的路径或类似的东西，只是因为我不喜欢向我的计算机广播世界。****

我正在安装许多不同的节点包，以便运行来自我的编码指导员的预先创建的程序。有两个特定的输出部分，我不明白如何解决。第一个是关于“设置PYTHON env变量”，第二个是关于我从未听说过的“ELIFECYCLE”。以下是我在尝试解决这两个问题时所做的工作：

1）我已经安装了Python，Python版本是Python 3.6.4，日期为“2017年12月19日”。从我的节点项目的位置，我已经可以在命令行中输入“python”，并在Python32上出现Python解释器：'Python 3.6.4（v3.6.4 .......等）。输入“帮助”，“版权”或“许可证”以获取更多信息“'。 - 现在这是第一个错误对我没有意义的地方。当我可以清楚地输入Python并启动解释器时，怎么能找不到Python可执行文件？我不明白的是什么？显然我有些不对劲，但我不知道是什么。

2）我尝试了多种不同的方法来安装python并设置路径，实际上是3。第一个，在CMD窗口中使用“set”命令（这不能按照我想要的方式工作，因为每次打开CMD线都要设置该参数。其次，我使用控制面板设置它，我也可以在完成之后拔出PYthon解释器。第三，我卸载了Python，当我进行干净安装时，我选中了“将python添加到系统变量”框。从那以后我运行我的python解释器没有问题CMD线。

3）我已经通过Stack Overflow搜索了关于这个特殊错误的许多不同问题，其中出现了很多，但是使用我已经完成的3种方法中的任何一种方式进行投票的解决方案都没有工作为了我。并且，似乎已经解决的其他问题仅仅是因为他们无法将python解释器从他们的项目路径（我可以做）中解决。所以，我只是不确定命令行是否正确识别错误。（我不知道，对于这些事情，我是一个完整的菜鸟。）

4）我在互联网上搜索了“ElifeCycle是什么”......但是我无法弄清楚该错误究竟是指什么。

所以我希望你们能帮助我解决有关Python错误和上面命令行输出中列出的“ELIFECYCLE”错误的两个问题。

非常感谢您花时间阅读本文。我知道这可能只是简单的事情。但我在这里结束了。我花了5个多小时试图解决这个问题，但没有任何工作。谢谢！
