如何在Windows 7中运行python 2和3？（win7运行python程序）

有没有一种方法可以在不破坏python 2的情况下在python 2上进行安装python 3？主要问题是我具有由“ python xxxxx.py
abc123”运行的代码。有没有办法将python 3更改为“ python3 xxxx.py abc123”？相同的命令python是冲突

答案1

小编典典

在Windows上有更好的共存/启动Python 2和Python 3的方法。Python 3.3引入了 适用于Windows 的
Python启动器
（请参见http://www.python.org/dev/peps/pep-0397/）。

安装Python
3.3后，将py.exe和pyw.exe复制到您的c:\Windows目录，并为.py扩展设置关联，以便它使用启动器。默认情况下，Python
2是针对推出的py script.py。在py -3 script.py启动Python
3的（这也意味着，对于Python中没有路径必须被加入到环境-C:\Windows已经在PATH。）

最好的是，#!python2脚本中的原因是通过Python 2#!python3启动，原因是通过Python
3启动。通过这种方式，您可以对两个版本的Python使用脚本，也可以统一使用它们-py script.py或仅单击脚本图标。

还有更多细节，但这基本上是您所需要的。

更新： 在Windows上使用Python启动器时，您还可以cmd通过在窗口中键入以下内容来启动Python脚本>script.py（即，无需py在脚本名称前显式键入-Python启动器的名称），或者甚至键入不带以下名称的名称在.py扩展（这只是>script）。

这样，事情开始类似于Unix的脚本命名方式（不需要扩展名）。但是，.py在创建脚本文件时，您仍然必须添加扩展名。

（是的，它比Unix的方法更混乱。这是OS开发的 “首先 考虑！” 和 “先出售！”
方法之间的区别。无论如何，我对Python开发团队的敬意深深吸引Windows中最好的-通过发布适用于Windows的Python启动器。）

node.js – 如何在Windows 7中运行gulp？

我试图在 Windows 7上运行gulp.我相信我有所有依赖项但是当我在默认的cmd或posh-git中输入gulp时,我收到以下错误：

gulp : The term 'gulp' is not recognized as the name of a cmdlet,function,script file,or operable program. Check the spelling of the name,or if a path was included,verify that the path is correct and try again.
At line:1 char:1
+ gulp
+ ~~~~
+ CategoryInfo          : ObjectNotFound: (gulp:String) [],CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

我该怎么做才能让它发挥作用？

以下是我在尝试安装gulp时收到的控制台消息

解决方法

更新#1

从npm输出看来,你安装的node.js版本太旧了：

npm WARN engine gulp@ 3.4.0: wanted: {
    "node": ">= 0.9"
}(current: {
    "node": "v0.8.22","npm": "1.2.14"
})

你的版本是0.8.22,gulp需要0.9或更新版本.首先尝试升级node.js,然后重试.

原始答案

要安装gulp,你需要运行：

npm install gulp -g

这将全局安装gulp,这意味着可以访问gulp.cmd

C:\Users\[yourAwesomeLogin]\AppData\Roaming\npm

所以,只需确保,你的PATH中有该目录.

Python 3.3.2 – 如何在Windows上运行脚本

我和Python没有任何关系，只需要为一个脚本添加一个前缀到Bootstrap CSS类就可以了。在“how-to”作者指示以这种方式调用脚本：

$python bootstrap_namespace_prefixer.py /path/to/boostrap/dir

所以在命令行我input

$python bootstrap_namespace_prefixer.py c:bootstrap

这是给我一个错误

File "",line 1 $python bootstrap_namespace_prefixer.py c:bootstrap ^ SyntaxError: invalid Syntax

这里是github脚本的链接正如我所说我不是Python程序员，只需要这个脚本来帮助我在我的工作，但不知道我在做什么错…

你有没有安装Python ？

安装Python ，选择你喜欢的任何版本： x64或x86 。

将Python添加到PATH ：

保持胜利，然后按暂停。

点击Advanced System Settings 。

点击Environment Variables 。

追加;C:python33到PATH变量。

重新启动cmd.exe或Powershell 。

尝试运行python bootstrap_namespace_prefixer.py c:bootstrap 。

python2和python3同安装在Windows上，切换问题

python2使用：py -2 name.py（name是自定义名字）

python3使用：py -3 name.py

使用python 自带的 2to3工具进行python2到python3的代码转换：

1.进入当前python2文件目录，把2to3工具复制到当前目录下

2. 终端cd到当前目录，运行 2to3 -w name.py

3.成功后，name.py文件是python3代码文件，name.py.bak为python2代码文件

生成代码运行不一定成功，主要看颜值，颜值不够有可能需要手动微调代码

python2安装MySQLdb（windows同时装有python2和3）

命令行：

py -2 -m pip install --upgrade pip #更新pip

py -2 -m pip install MySQL-Python

然后发现出错，

按照提示进入 http://aka.ms/vcpython27 网站，下载 VCForPython27.msi 进行安装，又发现错误

其实这时候已经安装成功，按照错误提示，缺少c++相关文件，前往

https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python下载相应文件，

我下载的是MySQL_python‑1.2.5‑cp27‑none‑win_amd64.whl，命令行进入下载文件对应目录

执行命令 py -2 -m pip install MySQL_python-1.2.5-cp27-none-win_amd64.whl

成功安装，再运行py -2 -m pip install MySQL-Python

如图：

成功安装！

再进入python shell检验，import MySQLdb，如图：

成功！
