我正在进入Node.js代码库,它要求我通过NPM下载一些依赖项,即jQuery。

在尝试运行npm install jquery时,我一直收到以下错误:

看起来失败是由于缺少Python安装。好吧,我已经安装了Python,设置了变量,然后重新启动,仍然是错误。

关于我遗漏了什么有什么线索吗?

如果没有安装python以及所有节点gyp依赖项,只需使用管理员权限打开Powershell或Git Bash并执行:

npm install --global --production windows-build-tools

然后要安装软件包:

npm install --global node-gyp

安装后,将下载所有节点gyp依赖项,但仍需要环境变量。Validate Python确实位于正确的文件夹中:

C:\Users\ben\.windows-build-tools\python27\python.exe 

Note - it uses python 2.7 not 3.x as it is not supported

如果它没有发出呻吟,请继续创建(用户)环境变量:

setx PYTHON "%USERPROFILE%\.windows-build-tools\python27\python.exe"

重新启动cmd,并通过set PYTHON验证变量是否存在,后者应返回变量

最后重新应用npm install <module>

这是一本为我解决了很多问题的指南。

http://www.steveworkman.com/node-js/2012/installing-jsdom-on-windows/

我特别记得python版本很重要。确保安装2.7.3而不是3

你的问题是你没有设置环境变量。

这个错误清楚地说明了这一点:

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

在你的评论中,你说你做到了:

set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib

这很好,但它没有设置PYTHON变量,而是设置PYTHONPATH变量。


同时,仅使用set命令只会影响当前的cmd会话。如果你在那之后重新启动,就像你说的那样,你最终会得到一个全新的cmd会话,其中没有设置该变量。

有几种方法可以永久地设置环境变量最简单的是在XP的系统控制面板中,这在Vista中当然是不同的,在7中又是不同的,在8中又是不同的,但是你可以用google搜索。

或者,只需在npm命令之前执行set,而不必在两者之间重新启动。


您可以通过执行与配置脚本完全相同的操作来测试您是否正确地完成了任务:在运行npm之前,请尝试运行%PYTHON%。如果你做得对,你会得到一个Python解释器(你可以立即退出)。如果你犯了错误,你就没有做对。


有两个问题:

set PYTHON=%PYTHON%;D:\Python

首先,将PYTHON设置为;D:\Python。对于以分号分隔的路径列表(如PATHPYTHONPATH),该额外分号是合适的,但对于单个值(如PYTHON)则不行。同样地,当您想将另一条路径添加到路径列表中,而不是为一个值添加一个新值时,您需要的是向现有值添加一个新值。所以,你只要set PYTHON=D:\Python

其次,D:\Python不是Python解释器的路径。它类似于D:\Python\Python.exe,或者D:\Python\bin\Python.exe。找到正确的路径,确保它独立工作(例如,键入D:\Python\bin\Python.exe,并确保获得了一个Python解释器),然后设置变量并使用它。


所以:

set PYTHON=D:\Python\bin\Python.exe

或者,如果你想让它永久,在控制面板中做同样的事情。
