您的 TeX 引擎未提供 \expanded 原语，listofitems v1.63 无法工作：加载 listofitems v1.61

设想

我正在 Windows 10 Pro N 设备上的 Anaconda 4.8.2 中从 python 3.6 编译 latex 文档。为此，我在 Anaconda Prompt 中创建了一个 python 3.6 环境，并使用命令在 anaconda 中安装了 miktex：

conda install -c conda-forge miktex

并执行以下 Python 代码：

def create_pdfV3(self, input_filename, output_filename):
        argList = [
            'pdflatex',   # Or maybe 'C:\\Program Files\\MikTex\\miktex\\bin\\latex.exe
            '-output-format=pdf',
            '-job-name=' + output_filename,
            input_filename,
            '-enable-installer']
        print(f'argList={argList}')
        process = subprocess.Popen(argList)

返回以下错误：

(C:\Users\someuser\AppData\Roaming\MiKTeX\2.9\tex\latex\listofitems\listofitems.sty
(C:\Users\someuser\AppData\Roaming\MiKTeX\2.9\tex\generic\listofitems\listofitems.tex

! Package listofitems Error: the \expanded primitive is not provided by your Te
X engine, listofitems v1.63 cannot work: loading listofitems v1.61.

See the listofitems package documentation for explanation.
Type  H <return>  for immediate help.
 ...

l.67    {\input listofitemsold.tex\relax\endinput}
                                                %
?

据我了解这个问题导致此错误的原因是，用于编译的 TEX 引擎main.tex未更新以包含\expanded原语。

pdflatex --version在 Anaconda prompt 的 python 3.6 环境中手动执行命令找到 pdflatex 使用的版本，结果如​​下：

pdflatex --version

问题

如何切换 TEX 引擎以启用原语编译\expanded？
