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

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。

其他回答

其中一个和/或多个应该有助于:

Add C:\Python27\ to your PATH variable (considering you have Python installed in this directory) How to set PATH env variable: http://www.computerhope.com/issues/ch000549.htm Restart your console and/or Windows after setting variable. In the same section as above ("Environment Variables"), add new variable with name PYTHON and value C:\Python27\python.exe Restart your console and/or Windows after setting variable. Open Windows command line (cmd) in Admin mode. Change directory to your Python installation path: cd C:\Python27 Make symlink needed for some installations: mklink python2.7.exe python.exe

请注意，您应该有Python 2。x，不是3。X，运行基于node-gyp的安装!

下面的文本说的是Unix，但Windows版本也需要Python 2.x:

You can install with npm:

$ npm install -g node-gyp
You will also need to install:

On Unix:
python (v2.7 recommended, v3.x.x is not supported)
make
A proper C/C++ compiler toolchain, like GCC

这里有一个指南，为我解决了很多这些问题。

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

我记得python版本特别重要。确保你安装了2.7.3而不是3。

这有帮助:https://www.npmjs.com/package/node-gyp

我是这样做的:

npm install -g node-gyp

然后:

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

我尝试了上面所有的步骤，没有一个对我有效。我试图通过yarn在windows 10系统上安装argon2 npm包。

这就是最终成功的方法

I ran npm --add-python-to-path='true' --debug install --global windows-build-tools to install python as an admin in command terminal the above command ran into an infinite loop which you can terminate by using Ctrl + C. I set the environment variable by running this setx PYTHON "%USERPROFILE%\.windows-build-tools\python27\python.exe" I installed node-gyp globally by running this command npm install --global node-gyp I downloaded VS 2019 community edition installer, while installing I added desktop development with C++ as shown in the image I ran the yarn command again. for e.g yarn add argon2

我希望这些步骤能帮到你。我花了几个小时才找到答案

对我来说，这些步骤解决了问题:

1-以管理员身份运行命令:

NPM install -global -production windows-build-tools

2-然后在第一步完成后运行npm重建(特别是完成python 2.7安装，这是问题的主要原因)
