導入模塊 PyPDF2 時出現 Xonsh 錯誤

Question

我在從安裝到虛擬環境的 xonsh 腳本中導入模塊時遇到問題。

我使用vox安裝了虛擬環境

xontrib load vox
vox activate venv
pip install PyPDF2

這是我的最小例子

#!/usr/bin/env xonsh
import PyPDF2

如果我從 Python 解釋器中運行它，它會工作：

 $ python         
Python 3.8.10 (default, Nov 26 2021, 20:14:08) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyPDF2
>>> 

如果我嘗試將 xonsh 腳本作為腳本運行，我會得到以下信息：

$ ./minimaltest.x
                                                                 sh

    func(code, glb, loc)
  File "./minimaltest.xsh", line 2, in <module>
    import PyPDF2
ModuleNotFoundError: No module named 'PyPDF2'

有什么想法可能是錯誤的嗎？

xonsh只能導入存在於與其安裝相同的venv中的模塊。如果將xonsh安裝到與venv相同的PyPDF2中，它應該可以工作。
