当我向 .bib 文件添加条目并保存它时，编译时出现以下错误：
格式化失败。请参阅 LaTeX Workshop 输出了解详情。
按照提示，我在“输出”窗格的“LaTeX Workshop”选项卡中看到：

我已经在（根据和）安装了cpan和。我尝试安装但无法安装。不过，这个错误消息令人困惑，因为错误perl/usr/bin/which perlwhich cpanFile::HomeDir未被抛出如果我在此会话中没有修改 bibfile.bib。例如，如果我保存 bibfile 并重新启动 VS Code，问题就会“消失”。
答案1
解决方案如下：
latexindent：无法在@INC 中找到 Log/Log4perl.pm（您可能需要安装 Log::Log4perl 模块）
这篇文章最初对我不起作用的原因是我使用的是 Mac 的默认版本和perl5.18 cpan，并且这些版本安装在一个不容易访问的文件夹中cpan。在我运行brew install perl安装了 5.30 的之后/usr/local/bin，我能够按照上述链接中所述解决问题。
