这个问题是根据我在本地安装 jsbin 时遇到的问题创建的。JGallardo要求我从中创建一个问题,因为最初我已经在原始问答中发表了评论(请点击链接查看它的内容)。

更新:由于审阅者删除了 Windows 标签,请注意我在Windows 7机器上遇到了问题。

该命令npm install jsbin对我不起作用 - 它会引发我不明白的错误: "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,在我的情况下这是必需的,因为我发现: npm config set proxy=http://servername:port. 现在它正在获取文件,当我调用 目录时 - 但它运行的时间很长npm install jsbin"c:\users\myuser\AppData\Roaming\npm-cache"现在它在说"can't find python executable"- 你知道这是哪个依赖吗?如果需要,我该如何安装 python 包?

得到上述错误后,我也尝试npn install python在运行前安装npn install jsbin。它也没有工作,我仍然收到错误 "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,虽然它似乎已安装?

注意,我现在还安装了官方来源path的官方 Python 解释器,并通过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,我已将环境变量设置为安装 python 系统PYTHON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)

我不知道为什么 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,它成功了。

步骤是:

  1. 安装巧克力。有关说明,请参阅Chocolatey 网站
  2. 打开管理员控制台,然后执行以下操作:

C:\WINDOWS\system32>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.

  For details on the all new Chocolatey, visit http://bit.ly/new_choco
Chocolatey (v0.9.8.33) is installing 'python' and dependencies. 
By installing you accept the license for 'python' and each dependency you are installing.
