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

骗子犯错!配置错误骗子犯错!堆栈错误:无法找到Python可执行文件“Python”，您可以设置PYT HON env变量。

没有必要重新安装，此异常由node-gyp脚本抛出，然后尝试重新构建。这是足够的设置环境变量，就像在我的情况下:

SET PYTHON=C:\work\_env\Python27\python.exe

其他回答

我也有同样的问题，这些答案都没有帮助。在我的例子中，PYTHON变量设置正确。然而，python安装得太深，即路径太长。所以，我做了以下事情:

重新安装python到c:\python 设置环境变量PYTHON为C:\ PYTHON \ PYTHON .exe

就是这样!

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)

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。

这里有一个指南，为我解决了很多这些问题。

我记得python版本特别重要。确保你安装了2.7.3而不是3。

2013-02-28 02:52:42

如果你没有安装python以及所有node-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

然后安装包:

npm install --global node-gyp

安装完成后，您将下载所有node-gyp依赖项，但仍然需要环境变量。在正确的文件夹中确实找到了Validate Python:

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

*注意-它使用python 2.7而不是3。X，因为不支持*

如果它没有呻吟，继续创建你的(用户)环境变量:

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

重新启动cmd，并通过设置PYTHON来验证变量是否存在，应该返回该变量(如果使用Powershell，则为$env:PYTHON)

最后，重新应用npm install <module>
