“找不到Python可执行文件...” - npm安装挂起 [英] "Can't find Python executable..." - npm install hangs
问题描述
我正在使用npm install来下载并编译我已经写过的一个小的node.js应用程序的所有依赖项。我使用的package.json文件是正确的，并且包含所有需要的信息。
I am using "npm install" to download and compile all the dependencies of a small node.js app I have written. The "package.json" file I am using is correct and contains all the needed information.
要安装的一个软件包中有一个node-gyp作为依赖，所以我以前安装了python2软件包。
One of the packages to be installed has "node-gyp" as a dependency, so I have previously installed the "python2" package.
现在，在某一点我开始收到错误消息：
Now, at a certain point I start getting error messages:
> node-gyp rebuild
gyp ERR! configure error
gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

gyp ERR! node -v v0.12.1
gyp ERR! node-gyp -v v1.0.3

问题似乎是一个环境变量丢失。
The issues seems to be that an environment variable is missing.
任何人都可以指向正确的方向吗？无论我在互联网上搜索的地方，还没有提到PYTHON变量，只有PYTHONPATH和其他人喜欢。解决这个问题的正确方法是什么？为什么我不会收到这些错误？
Can anyone point me in the right direction? No matter where I search on the Internet, there is no mention of a "PYTHON" variable, only "PYTHONPATH" and others like it. What is the correct way to fix this, so that I do not get those errors?
更新1：
在执行npm安装之后，我从以下线程中添加了这些命令：
After following advice from this thread I added these commands before executing "npm install":
PYTHON=/usr/sbin/python2
export PYTHON
现在我得到这个错误： / p>
Now I am getting this error:
> node-gyp rebuild
gyp ERR! build error
gyp ERR! stack Error: not found: make
gyp ERR! stack at F (/usr/lib/node_modules/npm/node_modules/which/which.js:40:28)

我发现荒谬的说，没有找到：做...。有可能是这样吗？如果是，如何安装包正确？
I find it absurd that it says "...not found: make...". Is there any possibility of it being so? If yes, how come packages install correctly?
坦白说，我不明白一件事情。任何想法？
Frankly, I do not understand a thing. Any ideas?
推荐答案
第一件事：我要感谢所有投入到帮助我的问题，特别是@ adarsh。
First things first: I want to thank all who pitched in to help me with my issue, and especially @adarsh.
现在真正的问题是我错过了make和gcc。起初，当一个编译器的消息建议如此，我发现它荒谬。但请记住，这是从Docker注册表中提取的图像。
Now the real issue was that I was missing "make" and "gcc". At first, when a compiler message suggested so, I found it absurd. But keep in mind that this is an image PULLed from the Docker registry.
我在Docker文件中添加了pacman -S - needed --noconfirm make gcc，构建过程成功完成。
I added "pacman -S --needed --noconfirm make gcc" in my Dockerfile, and the build process completes successfully.
不用说，我也需要对环境变量做出建议的修改。
It should go without saying, that I also needed to make the suggested changes to the environmental variables.
