Pandoc plot does not recognize the Matplotlib I installed

[fanrongqitiancai]

My running environment is Windows 7

1. Run the python command and the result is

python 3.8.5

2. Run the PIP list command to display

matplotlib 3.5.1

3. Run the pandoc plot toolkits command to display:

Toolkit: python/matplotlib

code block trigger: matplotlib

4. Markdown file

import matplotlib. pyplot as plt



plt. figure()

plt. plot([0,1,2,3,4], [1,2,3,4,5])

plt. title('This is an example figure')

5. Operation

pandoc --filter pandoc-plot --highlight-style pygments markdown. md -s -o output. html

6. Error reporting

renderer for python/matplotlib needed but is not installed

Hello there,

I'm sorry you're having trouble. I notice that your markdown file doesn't look like what pandoc-plot expects. Can you try the following file?

# My document

```{.matplotlib}
import matplotlib.pyplot as plt

plt.figure()
plt.plot([0,1,2,3,4], [1,2,3,4,5])
plt.title('This is an example figure')
```

It is important that your plotting code be 'sandwiched' between ```{.matplotlib} and ```

My document is in ``` 。I think there is a problem with pandoc plot or Python environment variables, which leads to incorrect identification. My pandoc plot downloads exe files and communicates with Pando Exe is in the same directory.

Allright, let's turn on logging to see what's going on.

In the same repository as your file, can you create a file named .pandoc-plot.yml with the following content?

# .pandoc-plot.yml
logging:
    verbosity: debug

Then, if you run the conversion command pandoc --filter pandoc-plot markdown.md -s -o output.html you should see a lot more information. Please copy and paste this information

I write Python code in eclipse,

import matplotlib. pyplot as plt

plt. figure()

Is right. However, I enter Python in the CMD command window,

Enter the command line and enter

import matplotlib. pyplot as plt

Display:

I modified the environment variable and it can work normally.

Awesome, I'll close this issue for now, but don't hesitate to reopen if it stops working
