如何在NPM安装过程中使用不同版本的python？ [英] How to use a different version of python during NPM install?

问题描述

Salam（意味着你好）：）

我有终端访问VPS运行centos 5.9和默认python 2.4.3安装。我也通过这些命令安装了python 2.7.3（我使用 make altinstall 而不是 make install ）

  wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz 
 tar -xf Python-2.7.3.tgz 
 cd Python-2.7.3 
 ./configure 
 make 
 make altinstall 
  
 
 
 
然后我通过这些命令从源代码安装node.js：
  python2.7 ./configure 
 make 
 make install 
  
问题是，当我使用 npm install ，并尝试安装一个node.js包需要python> 2.4.3我得到这个错误：
  gyp ERR！配置错误
 gyp ERR！ stack错误：Python可执行文件python是v2.4.3，不支持gyp。 
 gyp ERR！ stack您可以传递--python开关指向Python> = v2.5.0& < 3.0.0。 
 gyp ERR！ stack failPythonVersion（/usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:125:14）
 gyp ERR！堆栈在/usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:114:9 
  
我应该如何通过--python开关指向Python> = v2.5.0
？
解决方案
您可以使用  -  python 选项，如下所示：
  npm install --python = python2.7 
  
总是使用：
  npm config set python python2.7 
  
 Npm会在需要时将此选项传递给node-gyp。
 
 
 
那个在Github上打开了一个问题的人将其包含在文档中，因为有这么多问题;-)）
 
Salam (means Hello) :)

I have terminal access to a VPS running centos 5.9 and default python 2.4.3 installed. I also installed python 2.7.3 via these commands: (I used make altinstall instead of make install)
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
tar -xf Python-2.7.3.tgz
cd Python-2.7.3
./configure
make
make altinstall
then I installed node.js from source via these commands:
python2.7 ./configure
make
make install
The problem is, when I use npm install and try to install a node.js package which requires python > 2.4.3 I get this error:
gyp ERR! configure error
gyp ERR! stack Error: Python executable "python" is v2.4.3, which is not supported by gyp.
gyp ERR! stack You can pass the --python switch to point to Python >= v2.5.0 & < 3.0.0.
gyp ERR! stack     at failPythonVersion (/usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:125:14)
gyp ERR! stack     at /usr/local/lib/node_modules/npm/node_modules/node-gyp/lib/configure.js:114:9
how should I "pass the --python switch to point to Python >= v2.5.0"?
解决方案
You can use --python option to npm like so:
npm install --python=python2.7
or set it to be used always:
npm config set python python2.7
Npm will in turn pass this option to node-gyp when needed.

(note: I'm the one who opened an issue on Github to have this included in the docs, as there were so many questions about it ;-) )
