Python virtualenv 不会在 Windows 上激活

virtualenv won't activate on windows

提问by SScode

Essentially I cannot seem to activate my virtualenv environment which I create.

基本上我似乎无法激活我创建的 virtualenv 环境。

I'm doing this inside of windows powershell through using

我通过使用在 windows powershell 内部执行此操作

scripts\activate

but get an error message

但收到错误消息

"cannot be loaded because the execution of scripts is disabled on this system".

“无法加载，因为在此系统上禁用了脚本的执行”。

Could this be because I don't carry admin privileges on my computer?

这可能是因为我的计算机没有管理员权限吗？

According to Microsoft Tech Supportit might be a problem with Execution Policy Settings. To fix it, You should try executing Set-ExecutionPolicy Unrestricted -Forcein Your Power Shell.

根据Microsoft 技术支持，这可能是执行策略设置的问题。要修复它，您应该尝试Set-ExecutionPolicy Unrestricted -Force在您的 Power Shell 中执行。

NB: Remember to launch Power Shell as administrator.

注意：请记住以管理员身份启动 Power Shell。

Another quick solution I have found here (it is applicable for Windows Powershell only) is like this:

我在这里找到的另一个快速解决方案（它仅适用于 Windows Powershell）是这样的：

First run

第一次运行

Scripts\cmd

Then run

然后运行

Scripts\activate.bat

At this position, your Virtualenvis activated. Now if you deactivate it and want to activate it again later in the same session of powershell, you just need to run-

在这个位置，你的Virtualenv被激活。现在，如果您停用它并想稍后在 powershell 的同一会话中再次激活它，您只需要运行 -

Scripts\activate

There is no need to cmdor activate.batcommand later.

后面就不需要cmd或activate.bat命令了。

in windows you should activate the virtual environment by following command in cmd

在 Windows 中，您应该通过在 cmd 中执行以下命令来激活虚拟环境

E:\your_environment\Scripts>activate.bat

E:\your_environment\Scripts>activate.bat

if the environment is activatedthen it show your environment name enclosed with bracket like this

如果环境被激活，那么它会像这样显示用括号括起来的环境名称

(your_environment)E:\your_environment\Scripts>

(your_environment)E:\your_environment\Scripts>

Also we can ensure by checking with where.exeit will list our active python environment with order of hierarchy

我们也可以通过检查where.exe来确保它会按照层次结构的顺序列出我们的活动 python 环境

 (your_environment) E:\your_environment\Scripts>where.exe python

 E:\your_environment\Scripts\python.exe

 C:\Python27\python.exe

if you need to deactivatethen do

如果你需要停用然后做

(your_environment) E:\your_environment\Scripts>deactivate.bat

(your_environment) E:\your_environment\Scripts>deactivate.bat

This worked for me:

这对我有用：

You can simply open a normal (you do not need elevated access) cmd or powershell session (I use the embedded PS terminal in vscode) and type the following from the folder where the script file is e.g.: .venv\Scripts\Activate.ps1:

你可以简单地打开一个普通的（你不需要提升访问权限）cmd或powershell会话（我在vscode中使用嵌入式PS终端）并从脚本文件所在的文件夹中键入以下内容，例如.venv\Scripts\Activate.ps1：：

powershell.exe -executionpolicy unrestricted -command .\Activate.ps1 -Scope CurrentUser

powershell.exe -executionpolicy unrestricted -command .\Activate.ps1 -Scope CurrentUser

and then you can run the activatecommand after that.

然后你可以在那activate之后运行命令。

Note: This will only allow that specific Script to run, and only by your logged in user.

注意：这将只允许该特定脚本运行，并且只能由您的登录用户运行。

If you don't want to change your computer's execution policy on windows like I do, you can use windows command prompt instead of windows powershell, and just need to run Scripts\activateto activate your env

如果您不想像我一样在 windows 上更改计算机的执行策略，则可以使用 windows 命令提示符而不是 windows powershell，只需运行 Scripts\activate以激活您的 env
