although I installed python and can run it from console:
虽然我安装了 python 并且可以从控制台运行它：
# python
Python 2.7.3 (default, May 9 2014, 12:18:32)
[GCC 4.8.2] on linux2
and set up PATHin ~/.bashrc:
并设置PATH在~/.bashrc：
export PYTHONPATH=$PYTHONPATH:/Python-2.7.3
export PATH=$PATH:/Python-2.7.3
and done . ~/.bashrc
并做了 . ~/.bashrc

In your bash session where you're able to just type pythonand get a valid response, type in which pythonand note the full path location of the pythonbinary. Take that location and put that into your PYTHONPATHand PATHenvironment variables, except without the pythonat the end.
在 bash 会话中，您只需输入python并获得有效响应，输入which python并记下python二进制文件的完整路径位置。获取该位置并将其放入您的PYTHONPATH和PATH环境变量中，除非最后没有python。
For example, which pythongives me:
例如，which python给我：
/usr/local/bin/python
so I would write:
所以我会写：
export PYTHONPATH=$PYTHONPATH:/usr/local/bin
export PATH=$PATH:/usr/local/bin
in my ~/.bashrc.
在我的~/.bashrc.
回答by Maxim Yefremov
the problem was because of ~/.bashrcwas not loaded on ssh login. I put PATHvars to ~/.bash_profileand it's ok
问题是因为~/.bashrc没有在 ssh 登录时加载。我把PATHvars放到了~/.bash_profile，没关系

For anyone encountering this issue on Ubuntu 16.04...node-gypcan't use Python 3.5.X which seems to the be the default that ships with 16.04. I read somewhere that 16.04 was supposed to ship with Python2 as well but I can't find it on my install.
对于在 Ubuntu 16.04 上遇到此问题的任何人...node-gyp不能使用 Python 3.5.X，这似乎是 16.04 附带的默认值。我在某处读到 16.04 也应该随 Python2 一起提供，但我在安装时找不到它。
I fixed the above issue by:
我通过以下方式解决了上述问题：
apt-get update
apt-get install python2.7
ln -s /usr/bin/python2.7 /usr/bin/python
Now when node-gypgoes looking for pythonit will hit your Python2.7 install and load correctly.
现在，当你node-gyp去寻找python它时，它会命中你的 Python2.7 安装并正确加载。

Just delete node_modulesfolder and run npm installor yarn installagain.
只需删除node_modules文件夹并运行npm install或yarn install再次运行。
