"当我尝试使用 venv 激活虚拟环境时出现错误"

Question

I am following this tutorial on how to set up a virtual environment in Python3.6 using the windows command prompt. I had no problem generating the necessary file by running this:

python3 -m venv venv-test

The tutorial then advises to activate the virtual environment by running this code:

venv-test/Scripts/activate

But when I do this , I get the error...

 File "venv-test/Scripts/activate", line 4
    deactivate () {
              ^ SyntaxError: invalid syntax

I opened the generated 'activate' file and this seems to be the part that's causing the problem but I'm not sure how to correct it.

deactivate () {
# reset old environment variables
if [ -n "${_OLD_VIRTUAL_PATH:-}" ] ; then
    PATH="${_OLD_VIRTUAL_PATH:-}"
    export PATH
    unset _OLD_VIRTUAL_PATH
fi
if [ -n "${_OLD_VIRTUAL_PYTHONHOME:-}" ] ; then
    PYTHONHOME="${_OLD_VIRTUAL_PYTHONHOME:-}"
    export PYTHONHOME
    unset _OLD_VIRTUAL_PYTHONHOME
fi

Thanks in advance!

Answer 1

Try this:

source venv-test/bin/activate

It worked here. Make sure you're in the folder that contains your venv, otherwise just mention its full path.

Answer 2

I haven't got access to a windows machine at the moment but if I remember correctly you need to run activate.bat and I think you need the full path.

So something like:

C://code/project/venv-test/Scripts/activate.bat

Answer 3

not sure the reason why running

venv-test/Scripts/activate

doesn't work but if you go into the directory venv-test/Scripts and THEN type activate it works fine.

Answer 4

在 Python 3.8 上，只需转到包含虚拟环境的文件夹并键入

source venv-test\scripts\activate

Answer 5

你必须运行 source venv-test/bin/activate 而不是 venv-test/Scripts/activate

Answer 6

I had the same problem before, try typing :

venv-test/Scripts/activate.bat,

it worked for me

Answer 7

change directory to scripts directory as follows:

cd venv-test/Scripts

and run the activate file by typing

activate 

at the prompt
