Have you installed LaTeX properly? Because your shell told you that sh: latex: command not found.

[ppamorim]

@TonyCrane Yes it's installed.

[TonyCrane]

try running latex --version ?

[ppamorim]

MacBook-Pro:t-pro-ios ppamorim$ latex --version
-bash: latex: command not found

So mactex is installed but I can't use it. I am running this on a M1 machine.

[node-rookie]

I have the same problem, solved by adding LaTex to the environment variable

Hi @TonyCrane ,

Would you mind to help me to take a look at this issue? The .tex file was generated by manimlib, and here is the err log

@gxshao Your problem has nothing to do with this issue, so please open a new issue to explain your problem, and please paste your code.

Windows解决方案

• 1.在C盘创建TempLatex(具体什么名字按你的喜好来)目录
• 2.在manim(manimgl版本)目录中找到manimlib/default_config.yml并使用文本编辑器打开
• 3.修改第18行 之前：temporary_storage: "" 之后：temporary_storage: "C:/TempLatex"
• 4.保存

English

Windows Solution

• 1.Create TempLatex directory in C drive
• 2.Find manimlib/default_config.yml in the manim (manimgl version) directory and open it with a text editor
• 3.Modify line 18: before: temporary_storage: "" after: temporary_storage: "C:/TempLatex "
• 4.Save

@TonyCrane brew install mactex, where to find latex command?

[alexrintt]

The reason behind this exception is because the temporary directory in windows contains a ~ which for some reason breaks something (some internal logic of the library, or character encoding limitation)

So you can fix by setting up a new directory inside custom_config.yml:

# I use the D: drive but this can be any folder from any drive
# Just make sure to contains only alpha characters (a-zA-Z)
directories:
  temporary_storage: D:\TempStorage # Must exists and should be an empty folder

[vtnil]

I have the same problem, solved by adding LaTex to the environment variable.

export PATH="/usr/local/texlive/2022/bin/universal-darwin:$PATH"

The reason is the MacTeX installer not update the environment variable automatically.

[technixp]

For 2023 it's export PATH="/usr/local/texlive/2023/bin/universal-darwin:$PATH"
