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

下面是正确的命令:set path=%path%;C:\Python34[替换为正确的python安装路径]

我遇到过同样的问题，我就这样解决了。

正如其他人指出的那样，这是一个易变的配置，它只对当前的cmd会话有效，并且(显然)你必须在运行npm install之前设置路径。

我希望这能有所帮助。

其他回答

我在下载Akveo ngx-admin模板后尝试执行“npm install”时遇到了同样的错误。

这是一种奇怪的情况，因为我只是在另一台笔记本电脑上启动了相同的模板。我意识到我安装了antoher versión的npm。

如你所见，我的节点版本是“14.17.0”，第一步我的npm版本是“7.13.0”。然后我意识到我的另一台笔记本电脑上的npm版本是“6.14.11”，所以我决定通过执行“npm install -g npm@6.14.11”来降级npm版本。

然后“npm install”运行得非常好。

注意: 不需要安装windows-build-tools或任何python版本。

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

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。

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!

设置路径如下，它将工作

> set PYTHON=D:\\ranjith\\installed\\python-3.6.4\\python.exe

> npm config set python D:\\ranjith\\installed\\python-3.6.4\\python.exe

然后建立你的项目(对我来说)

> yarn build
