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

并在PATH中设置~/.bashrc：

export PYTHONPATH=$PYTHONPATH:/Python-2.7.3
export PATH=$PATH:/Python-2.7.3

并完成. ~/.bashrc

Answer 1

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。我在某地读过16.04也应该附带Python2但我在安装时找不到它。

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

现在当node-gyp寻找python时，它会点击你的Python2.7安装并正确加载。

Answer 2

在您的bash会话中，您只需输入python并获得有效回复，请输入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，但最后没有python。

例如，which python给了我：

/usr/local/bin/python

所以我会写：

export PYTHONPATH=$PYTHONPATH:/usr/local/bin
export PATH=$PATH:/usr/local/bin

在我的~/.bashrc。

Answer 3

问题是由于~/.bashrc未在ssh登录时加载。我将PATH变量放到~/.bash_profile并且没关系

Answer 4

有一个简单又安全的方法将其放入 ~/.bashrc 或 ~/.bash_aliases 文件：

alias python=python3

在文件中添加以上内容后，运行source ~/.bashrc或source ~/.bash_aliases

此解决方案适用于我的 Ubuntu 查看原始答案 here

Answer 5

只需删除 node_modules 文件夹，然后再次运行npm install或yarn install。

Answer 6

安装python2.7。
apt install python2

找不到Python可执行文件“python”
