无法在Windows 10中激活Python venv [英] Can't activate Python venv in Windows 10
问题描述
我从命令提示符下使用 python -m venv myenv 创建了一个虚拟环境，但是我不知道如何激活它。我尝试从命令提示符处执行 activate.bat ，但它没有激活。
I created a virtual environment with python -m venv myenv from the command prompt, but I don't know how to activate it. I tried executing activate.bat from the command prompt but it does not activate.
换句话说，我不知道没有看到当前路径更改为（myenv）C：\路径名... 表示myenv已被激活。当我执行 activate.bat 时，虚拟电话未激活。
In other words, I don't see the current path changed to (myenv) C:\Pathname... to indicate that myenv has been activated. When I execute activate.bat the venv is not activated.
推荐答案
这个线程很旧，但是今天我遇到了同样的问题，并找到了可行的答案。我一直在使用python 3.6 venv几个月，没有任何问题，但是今天我遇到了一条新的错误消息：
This thread it old but I had the same problem today and found a working answer for it. I've been using python 3.6 venv for a few months now without issues but today I ran across a new error message:
C:\test>python -m venv vm
Error: Command '['C:\\test\\vm\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
我搜寻了Stack和其他资源来寻找答案，但是没有找到Windows 10的特定内容。（AskUbunto有一个Linux特定的解决方案）。我确实发现面包屑散布在整个InterWeb上，并将它们拼凑在一起。
I scoured Stack and other resources for an answer but didn't find anything specific to Windows 10. (AskUbunto had a solution that was specific to Linux). I did find breadcrumbs spread out across the InterWebs and pieced this together.
您需要以下python脚本： https://bootstrap.pypa.io/get-pip.py

照常安装虚拟环境，但没有pip：
Install your virtual environment as usual but without pip:
python -m venv virtual --without-pip
python -m venv virtual --without-pip
此方法将创建所有必需的文件，包括激活蝙蝠文件。
This method will create all of the necessary files including the activate bat files.
-
将get-pip.py文件复制到virtual\Scripts子目录
Copy the get-pip.py file into the virtual\Scripts subdirectory
cd进入Scripts子目录并激活 python注意：cmd行应命名从中激活python的目录：
cd into the Scripts subdirectory and "activate" python Note: the cmd line should name the directory from which python was activated:
（虚拟）C：＼ ＼test\virtual\Scripts>
(virtual) C:\test\virtual\Scripts>
（如果显示（root），则表示已激活您的核心安装）
(if it says (root), it's activated your core installation)
-
现在执行脚本
now execute the script
C：\test\virtual\Scripts> python get-pip.py
C:\test\virtual\Scripts>python get-pip.py
一次运行，我输入：
(virtual) C:\test\virtual\Scripts>pip freeze
生成冻结列表并验证正确的安装。它应该什么也不返回，没有错误消息，没有冻结列表。
to generate a freeze list and verify proper installation. It should return nothing, no error msg, no freeze list.
- 然后我安装了烧瓶，尝试了pip冻结并记下返回仅适用于flask和相关文件：
（虚拟）C：\test\ virtual\脚本> pip冻结
click == 6.7
烧瓶== 0.12.2
itsdangerous == 0.24
Jinja2 == 2.9.6
MarkupSafe == 1.0
Werkzeug == 0.12.2
(virtual) C:\test\virtual\Scripts>pip freeze
click==6.7
Flask==0.12.2
itsdangerous==0.24
Jinja2==2.9.6
MarkupSafe==1.0
Werkzeug==0.12.2
