使用批处理文件在 Anaconda 中激活 python 3 环境 [英] Activate python 3 environemnt in Anaconda with batch-file

问题描述

最近在win7上为我的python项目安装了Anaconda (1.9)

Recently installed Anaconda (1.9) for my python project on win7

安装后，我在这个页面中建立了一个python 3支持环境.我的下一个任务是使用内置批处理文件自动激活我的 python 环境.

After installation, I built a python 3 support environment with instruction in this page. My next task is to activate my python environment automatically with built-in batch file.

我使用了在开始菜单中找到的 [Anaconda 命令提示符] 快捷方式中的命令.它运行一个名为 [anaconda.bat]

I used the command in [Anaconda Command Prompt] shortcut I found in my start menu. It runs a batch-file called [anaconda.bat]

观察批处理文件后，我意识到它似乎能够接受一个输入参数，该参数应该是我想要激活的环境.所以我复制了快捷方式并将其修改为

After observing the batch file I realized it seems to be capable of taking an input argument that is supposed to be the environment I would like to activate. So I copied the shortcut and modified it as

C:WindowsSystem32cmd.exe /k "C:AnacondaScriptsanaconda.bat py3k"

然后我双击新的快捷方式，它打开了一个新的命令窗口，但是……指定的环境没有激活！

Then I double clicked on the new shortcut, it opened a new command window but...the designated environment did not activate!

if not "%1" == "" (

        echo No environment named "%1" exists in %ANACONDA_ENVS%
        goto :eof
    )
    set ANACONDA_ENV_NAME=%1
    set ANACONDA=%ANACONDA_ENVS%\%1
    title Anaconda (%ANACONDA_ENV_NAME%^)
) else (
    set ANACONDA_ENV_NAME=
    for %%i in ("%~dp0..") do (
        set ANACONDA=%%~fi
    )
    title Anaconda
)

set ANACONDA_SCRIPTS=%ANACONDA%Scripts

for %%i in ("python.exe") do (
    for %%j in ("%ANACONDA%python.exe") do (
        if not "%%~f$PATH:i" == "%%~f$PATH:j" (
            set ANACONDA_OLD_PATH="%PATH%"
            set PATH=%ANACONDA%;%ANACONDA_SCRIPTS%;%PATH%;
            echo Added %ANACONDA% and %ANACONDA_SCRIPTS% to PATH.
        )
    )
)

if not "%ANACONDA_ENV_NAME%" == "" (
    echo Activating environment %ANACONDA_ENV_NAME%...
    set PROMPT=[%ANACONDA_ENV_NAME%] $P$G
)

我对蝙蝠语言的经验很少，但我想这行可能与此有关

I have very little experience with bat language but I guess there may be something to do with this line

setlocal enableextensions enabledelayedexpansion

我试图删除该行，但一直被困在带有消息的 ERRORLEVEL 1 表达式中.

I tried to remove that line but kept trapped in the ERRORLEVEL 1 expression with message.

error: unable to enable command extensions

谁能建议我应该怎么做才能使这个 bat 文件正常工作?

Can anyone suggest what I should do to make this bat-file work properly?

推荐答案

我认为你不需要批处理文件.假设 Anaconda 和 CMD 在你的路径上(它们应该是)，你可以试试这个作为替代方法(这就是我所做的):

I don't think you need a batch file. Assuming that Anaconda and CMD are on your path (which they should be), you can try this as an alternative (it is what I do):

cmd "/c activate py3k && ipython --pylab"
