在Windows上运行Python以获得Node.js依赖

我正在进入一个Node.js代码库，这需要我通过NPM下载一些依赖项，即jQuery。

在尝试运行npm install jquery时，我一直得到这个错误:

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，仍然出现错误。

你知道我错过了什么吗?

当前回答

作为管理员，下面的命令行对我有用:

安装windows build-tools(这可能需要15-20分钟):

 npm --add-python-to-path='true' --debug install --global windows-build-tools

添加/更新环境变量:

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

安装node-gyp:

npm install --global node-gyp

将exe文件的名称从Python更改为Python2.7。

C:\Users\username\.windows-build-tools\python27\Python2.7

NPM install module_name——save

其他回答

我的问题的答案很简单。

我在安装Python时打开了一个Windows命令窗口。

安装Python后，我试图从该窗口启动Python。

解决办法对我来说很简单。

当我关闭命令窗口并打开一个新的命令窗口时，问题就消失了。

我必须打开一个新的命令窗口，以便path环境变量将包含Python的路径。

为你的python.exe创建一个名为python2.7.exe的副本或别名

我的python 2.7安装为D:\app\Python27\python.exe

无论我如何设置(并验证)PYTHON env变量，我总是得到这个错误:

gyp ERR! stack Error: Can't find Python executable "python2.7", you can set the PYTHON env variable.
gyp ERR! stack     at failNoPython (C:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\lib\configure.js:103:14)

原因是在node-gyp的config .js中，python可执行文件是这样解析的:

var python = gypp .opt .python || process.env.PYTHON || 'python'

结果发现，gypp .opt .python有值'python2.7'，因此重写process.env.PYTHON。

我通过为node-gyp正在寻找的python.exe可执行文件创建一个别名来解决这个问题:

D:\app\Python27>mklink python2.7.exe python.exe

该操作需要管理员权限。

如果你想在Cygwin上使用这个，那么你需要遵循这个答案中的说明。(Cygwin如何处理Windows符号链接是个问题。)

正确的方法是 1)从这里下载并安装python 2.7.14。 2)设置python的环境变量。

完成了!

注:请设置相应的环境变量。我在这里回答窗户。
