这个问题是我在尝试在本地安装jsbin时遇到的问题创建的。 JGallardo要求我创建一个问题,因为我最初在original Q&A发布了评论(请点击链接查看其中的内容)。
更新:由于审核人员已删除了Windows标记,因此请注意我在 Windows 7 计算机上遇到了问题。
命令npm install jsbin
对我不起作用 - 它会抛出一个我不明白的错误:
"npm ERR! Error: getaddrinfo EAGAIN npm ERR! at errnoException (dns.js:37:11) npm ERR! at Object.onanswer [as oncomplete] (dns.js:124:16)"
我已经设置了一个代理服务器,我发现这是我需要的:
npm config set proxy=http://servername:port
。
现在,当我将npm install jsbin
调用到时,它正在获取文件
"c:\users\myuser\AppData\Roaming\npm-cache"
目录 - 但它运行的时间很长。现在它说"can't find python executable"
- 你知道这是什么依赖吗?如果需要,我该如何安装python包?
收到上述错误后,我还尝试在运行npn install python
之前安装npn install jsbin
。它也没有用,我仍然得到错误
"Error: Can't find Python executable "python", you can set the PYTHON env variable."
你能帮助在本地安装jsbin吗?为什么npm找不到python包虽然好像已经安装了?
N.B。我现在还安装了official source的官方Python解释器,并通过path
环境变量验证了它是否可用:
Your environment has been set up for using Node.js 0.10.12 (x64) and npm.
C:\>python
Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:06:53) [MSC v.1600 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
另外,我已将PYTHON
环境变量设置为安装python系统的路径C:\Python33
。
我得到的错误是:
gyp ERR! configure error
gyp ERR! stack Error: spawn ENOENT
gyp ERR! stack at errnoException (child_process.js:980:11)
gyp ERR! stack at Process.ChildProcess._handle.onexit (child_process.js:771:34)

gyp ERR! node -v v0.10.12
gyp ERR! node-gyp -v v0.10.0

答案 0 :(得分:0)
我无法找出为什么NPN没有安装python,但后来我用不同的安装程序choco (or Chocolatey)尝试了它,这成功了。
步骤是:
C:\WINDOWS\system32>
的 choco install python

!!ATTENTION!!
The next version of Chocolatey (v0.9.9) will require -y to perform
behaviors that change state without prompting for confirmation. Start
using it now in your automated scripts.

Chocolatey (v0.9.8.33) is installing 'python' and dependencies.
By installing you accept the license for 'python' and each dependency you are installing.
