通过Jupyter笔记本从GitHub安装模块 [英] Installing module from GitHub through Jupyter notebook

问题描述

我第一次尝试从GitHub安装某些东西，但在这里和谷歌搜索后找不到一个简单的解决方案。

我使用Jupyter笔记本，试图安装此模块：

https：/ /github.com/Expt-David/NumSchrodingerEq

我试图在笔记本中写下这个内容：

 ！pip install git + git：//github.com/Expt-David/NumSchrodingerEq.git 
  

但我收到以下错误：

 收集git + git ：//github.com/Expt-David/NumSchrodingerEq.git 
将git：//github.com/Expt-David/NumSchrodingerEq.git克隆到c：\ users \greatg〜1 \appdata\ local \temp\pip-1w_dpw43-build 
错误[WinError 2]执行命令时系统找不到指定的文件git clone -q git：//github.com/Expt-David/NumSchrodingerEq.git C ： \\ Users \GREATG〜1 \AppData\Local\Temp\pip-1w_dpw43- build 
找不到命令'git'
您使用的是pip版本8.1.2，不过版本9.0。 1可用。 
您应该考虑通过'python -m pip install --upgrade pip'命令进行升级。 
  

编辑

<看来再次安装git并手动删除路径并编辑我自己的问题，但现在我得到了：

 收集git + https：//github.com/Expt-David/NumSchrodingerEq.git 
将https://github.com/Expt-David/NumSchrodingerEq.git克隆到c：\users\greatg〜1 \appdata\local\temp\pip -zpuki8tu-build 
从命令python setup.py完成输出egg_info：
 Traceback（最近一次调用最后一次）：

 --------------------------------------- -  
命令python setup.py egg_info失败，错误代码1在C：\ Users \GREATG〜1 \AppData\Local\Temp\pip-zpuki8tu-build\ 
  

我已经安装并更新了setuptools。

我是否做错了？

谢谢！

解决方案

从PATH确实包含Git安装路径的会话中运行Jupyter Notebook。

和 c heck out pip issue 2109 ：

在我的情况中，问题在于我在windows上的路径环境中定义了git路径。

在 pip.util 中声明的函数find_command在带引号的句柄路径中失败，如：

  PATH = ...; c：\python27\\scripts;c：\\ \\ Program Files \git\cmd; C：\ Tcl\bin; ... 
  

< blockquote>

当它追加 git.exe 文件名来检查它的存在时，它会保留符号并且检查失败。

这应该在最近版本的pip中修复，但是再次检查您的％PATH％ 。

---

如果仍然失败，请尝试使用简化路径，并将Git安装在不带空格的简短PATH中：

p>

• 使用最新Git for Windows （解压缩Git 2.13 PortableGit-2.13.2-64-bit.7z.exe 随时随地 C：\Git2.13.2 ）


• 设置一个简化的 PATH 。

关于 PATH 问题，请输入（在<$ c

  set PATH = C：\ WINDOWS \ system32; C ：\ WINDINDOWS; C：\WINDOWS\System32\Wbem; C：\WINDOWS\System32\WindowsPowerShell\v1.0\ 
 set GH = C：\Git2.13.2 
 set PATH =％GH％\ bin;％GH％\usr\bin;％GH％\mingw64\bin;％PATH％
  

添加到 PATH 您需要的python / pip。

然后再试一次。

---

对于第二条错误消息，请考虑 pip安装错误没有这样的文件或目录： setup.py ，并仔细检查您的Python版本： pip 用于python 2. pip3 用于python 3。

My first time trying to install something from GitHub, but couldn't find a simple solution after searching here and on google.

I'm using Jupyter notebook and trying to install this module:

https://github.com/Expt-David/NumSchrodingerEq

i've tried to write this inside the notebook:

!pip install git+git://github.com/Expt-David/NumSchrodingerEq.git

but i'm getting the following error:

Collecting git+git://github.com/Expt-David/NumSchrodingerEq.git
  Cloning git://github.com/Expt-David/NumSchrodingerEq.git to c:\users\greatg~1\appdata\local\temp\pip-1w_dpw43-build
  Error [WinError 2] The system cannot find the file specified while executing command git clone -q git://github.com/Expt-David/NumSchrodingerEq.git C:\Users\GREATG~1\AppData\Local\Temp\pip-1w_dpw43-build
Cannot find command 'git'
You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

EDIT

Seems that installing git again and manually delete the path and edit myself worked for that issue, but now i'm getting:

Collecting git+https://github.com/Expt-David/NumSchrodingerEq.git
  Cloning https://github.com/Expt-David/NumSchrodingerEq.git to c:\users\greatg~1\appdata\local\temp\pip-zpuki8tu-build
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "d:\anaconda3\lib\tokenize.py", line 454, in open
        buffer = _builtin_open(filename, 'rb')
    FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\GREATG~1\\AppData\\Local\\Temp\\pip-zpuki8tu-build\\setup.py'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\GREATG~1\AppData\Local\Temp\pip-zpuki8tu-build\

And I have setuptools installed and updated.

What am I doing wrong ?

Thanks!

解决方案

Make sure you run your Jupyter Notebook from a session where PATH does include the path to your Git installation.

And check out pip issue 2109:

In my case the problem was the way I had the path to git defined in my path environment on windows.

the function find_command declared in pip.util fails in handle paths with quote, like:

PATH=...;c:\python27\scripts;"c:\Program Files\git\cmd";C:\Tcl\bin;...

when it appends the git.exe filename to check its existence it keeps the " symbol and the check fails.

That should be fixed in recent version of pip, but again, double-check your %PATH%.

---

If that still fails, try with a simplified path, and Git installed in a short PATH without space:

• use the latest Git for Windows (uncompress Git 2.13 PortableGit-2.13.2-64-bit.7z.exe anywhere you want, for instance in C:\Git2.13.2)
• set a simplified PATH.

Regarding the PATH issue, type (in a CMD):

set PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
set GH=C:\Git2.13.2
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%

Add to that PATH what you need for python/pip.
Then try again.

---

For your second error message, consider "pip installation error "No such file or directory: setup.py"", and double-check your version of Python: pip is for python 2. pip3 is for python 3.
