安装vpnotebook时，点提示错误

Question

无法从其网站上获得Vpython版本，但根据https://groups.google.com/forum/#!topic/vpython-users/AmIZF2v4Wkc的说明 ，“ pip install vpython”适用于任何Python版本。 我在Windows命令提示符下输入了“ pip install vpython”。 下载几分钟后，pip给了我以下错误：

Answer 1

即时修复是在安装vpnotebook之前安装jupyter：

pip install jupyter

Answer 2

这似乎是vpython依赖的vpnotebook的错误。 尝试在Python 2.7和3.5中都安装vpnotebook失败，并出现相同的错误，这似乎是由软件包的作者甚至没有使用基本的linter引起的。 我建议将其报告给上述作者，但该软件包的PyPI页面上没有列出详细的联系信息，存储库或项目网站 。

如果您的python版本大于2.7.9，请跳至步骤3

1. 安装python版本> 2.7.9 [2.7.14是最新的]

   • 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

   • curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
   • sudo python get-pip.py

3. 首先安装jupyter

   • sudo pip install jupyter

4. 然后，安装vpython

   • sudo pip install vpython
