LaTeX 中的 Asymptote 执行出现问题：“无法创建目录 /.asy。”

问题描述 投票：0回答：1

注意：我最初在 TeX Stack Exchange 上问过这个问题，但不幸的是，我没有收到回复。我将其重新发布到此处以获得更广泛社区的帮助。

这是原始帖子的链接：https://tex.stackexchange.com/questions/700578/asymptote-code-generates-asy-files-but-asymptote-execution-fails

这个问题进一步探讨了我之前在 TeX.SE 上的一项查询中解决过的问题： https://tex.stackexchange.com/questions/700514/asymptote-error-missing-pdf-file-during-compilation

在使用包含 Asymptote 代码的 LaTeX 文档时，我遇到了一个特殊问题。 LaTeX 编译似乎生成了必要的 

.asy
文件，但是当我尝试对这些文件单独执行 Asymptote 时，我遇到了困难。

这是我所采取的设置和步骤：

  • 我使用的是 Windows 操作系统。
  • 我已成功安装 LaTeX、Asymptote 和 Ghostscript，并已验证所有这三个都包含在我的系统的 PATH 中。
  • 我在编译 LaTeX 文档时使用 -shell-escape 选项。

LaTeX 编译日志表明 Asymptote 代码正在正确执行，因为我观察到 PDF 文件的生成

(asymptote-latex-1.pdf)
。但是，当我尝试在生成的 
.asy
文件上手动运行 Asymptote 时，它不起作用。

我尝试使用以下命令来运行 Asymptote：

  1. asy "C:\Users\twill\OneDrive\Desktop\ASYMPTOTE\output-directory\asymptote-latex-1.asy"
  2. asy C:\Users\twill\asymptote-latex-*.asy

尽管如此，我还是遇到了问题，Asymptote 似乎无法正确处理文件。我面临的具体错误消息是：

failed to create directory /.asy.
。 LaTeX 编译的日志没有提供任何与 Asymptote 相关的错误消息。

有没有人遇到过类似的问题，LaTeX 编译生成 

.asy
文件，但对这些文件执行 Asymptote 失败？我将非常感谢任何见解、故障排除步骤或解决方案，以确保 Asymptote 代码正确处理 
.asy
文件。

感谢您的协助。

在我大学教授的帮助下，问题已经解决了！

以下是我采取的步骤（供将来自我参考以及其他遇到同样问题的人）。

第1步：卸载ghostscript和miktex

第2步：安装miktex和最新的ghostscript。

第3步：全局搜索mgs并将其更改为其他内容（我使用mgstemp）

第四步：全局搜索gswin64.exe并将其名称更改为mgs

第5步：任何时候你更新MikTeX，它都会创建一个新的mgs文件（在MikTex目录！！！！！！）。您每次都需要将其更改为其他名称。

第 6 步：命令 

pdflatex test
然后 
asy test-1.asy
然后 
pdflatex test
将生成您的文档！
