Why am I not able to activate virtual environment in VS Code?

Question

When I run venv\Scripts\activate in cmd, I am able to use venv but in VS Code I can not use venv and I get this error:

PS F:\Python\Python-Inoventaa\Python Flask\FlaskProject\FlaskBlogProject> venv\Scripts\activate
venv\Scripts\activate : 
File F:\Python\Python-Inoventaa\Python Flask\FlaskProject\FlaskBlogProject\venv\Scripts\Activate.ps1 cannot be loaded because running scripts is disabled on

Answer 1

Try this: On the terminal of vs-code at the right side selected cmd instead of power shell.

Answer 2

You can solve it by adding this configuration to your settings.json file suggested from this issue

By going to your settings.json (on windows):

%APPDATA%\\Code\\User\\settings.json

or

C:\\Users\\<your user>\\AppData\\Roaming\\Code\\User\\settings.json

and adding this line in the configuration (use comma at the end if there are more config lines):

{
"terminal.integrated.shellArgs.windows": ["-ExecutionPolicy", "Bypass"]
}

and it should be solved once you open another Terminal.

Answer 3

You can use this script on VS Code's terminal:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process

for more detail you can visit official VS Code website about Python programming at https://code.visualstudio.com/docs/python/python-tutorial

Answer 4

更改为 cmd 而不是 powershell 肯定会在 vs code 中工作

Answer 5

As mentioned in the previous answer, it is due to execution policy of PowerShell terminal in VSCode.

To bypass the execution policy while using VSCode, you may add a modified PowerShell profile and set it as default profile in the JSON settings:

"terminal.integrated.profiles.windows": {
    "PowerShell venv": { 
        "source": "PowerShell", 
        "icon": "terminal-powershell", 
        "args": ["-ExecutionPolicy", "Bypass"] }},
"terminal.integrated.defaultProfile.windows": "PowerShell venv",

or you may also choose to modify the default PowerShell, mentioned by @John:

"terminal.integrated.profiles.windows": {
    "PowerShell": { 
        "source": "PowerShell", 
        "icon": "terminal-powershell", 
        "args": ["-ExecutionPolicy", "Bypass"] }},
"terminal.integrated.defaultProfile.windows": "PowerShell",

Answer 6

试试这个：在右侧的 vs-code 终端上选择 cmd 而不是 power shell。
