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

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

其他回答

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

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)

这是让NPM为你做所有事情的最简单的方法

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

在尝试安装node-sass@4.9.4时,我遇到了同样的挑战。

在查看了当前的官方文档并阅读了上面的答案后,我注意到您可能不一定要安装node-gyp或安装windows-build工具。这是关于在windows上安装node-gyp的。记住node-gyp涉及到node-sass的安装过程。你真的不需要重新安装另一个python版本。

这是救星,配置“npm”在安装任何需要构建工具的包时应该寻找的python路径。

C:\> npm config set python /Python36/python

我在windows-7上安装了python3.6.3。

对我来说, 问题是我使用的是node的最新版本,而不是LTS版本,LTS版本是稳定的版本,推荐给大多数用户。 使用LTS版本解决了这个问题。 你可在此下载:

LTS版

当前最新版本
