讓 pipenv 在 powershell 下開啟 shell 時顯示專案資料夾

#python #pipenv

不確定是我自己安裝的問題, 還是本來就如此, 在我的 powershell 中啟動 pipenv shell, 並不會在提示符號開頭顯示專案資料夾或是虛擬環境名稱, 像是這樣：

~/code/python/py3.10.11
# pipenv shell
Launching subshell in virtual environment...
PowerShell 7.4.1
Loading personal and system profiles took 532ms.
~/code/python/py3.10.11
#
Enter fullscreen mode Exit fullscreen mode

但是在 cmd 下卻沒問題：

C:\Users\meebo\code\python\py3.10.11>pipenv shell
Launching subshell in virtual environment...
Microsoft Windows [版本 10.0.22621.3007]
(c) Microsoft Corporation. 著作權所有，並保留一切權利。

(py3.10.11-tuTXJP8y) C:\Users\meebo\code\python\py3.10.11>
Enter fullscreen mode Exit fullscreen mode

它會把專案資料夾對應的虛擬環境名稱顯示出來。

經過搜尋, 似乎大家都有一樣的問題, 經過善心人士提供解決方案, 只要在 powershell 的 profile 中加入以下腳本即可：

if ($env:PIPENV_ACTIVE -eq 1) {

    function _OLD_PROMPT { "" }
    Copy-Item -Path function:prompt -Destination function:_OLD_PROMPT


    $_PROMPT_PREFIX = (($env:VIRTUAL_ENV -split "\\")[-1] -split "-")[0]

    function prompt {
        Write-Host -NoNewline -ForegroundColor Green "($_PROMPT_PREFIX) " 
        _OLD_PROMPT

    }
}
Enter fullscreen mode Exit fullscreen mode

這個腳本會在你的提示符號開頭插入專案資料夾, 像是這樣：

~/code/python/py3.10.11
# pipenv shell
Launching subshell in virtual environment...
PowerShell 7.4.1
Loading personal and system profiles took 1354ms.
(py3.10.11) ~/code/python/py3.10.11
#
Enter fullscreen mode Exit fullscreen mode
