Pip在安装vpnoteb时出错

Question

Vpython版本在他们的网站上没有，但是根据https://groups.google.com/forum/#!topic/vpython-users/AmIZF2v4Wkc，“pip install Vpython”应该适用于任何版本的Python。 我在windows命令提示符中输入了“pip install vpython”。下载几分钟后，pip给了我以下错误：

最直接的解决方法是在安装vpnotebook之前安装jupyter：

pip install jupyter

这似乎是vpnotebook中的一个bug，它依赖于vpython。尝试在Python2.7和3.5中安装vpnotebook失败，并出现相同的错误，这似乎是由于包的作者甚至没有使用基本的linter造成的。我建议将此报告给上述作者，但是there are no contact details, repositories, or project websites listed on the package's PyPI page。在

如果您的python版本高于2.7.9，请跳到步骤3

1. 安装python>；2.7.9[2.7.14是最新版本]

   • 下载最新版本的python
   • 提取档案
   • ./configure
   • make
   • make install

2. 下载并重新安装pip

   • ^{cd4}
   • sudo python get-pip.py

3. 先安装jupyter

   • sudo pip install jupyter

4. 然后，安装vpython

   • sudo pip install vpython
