在尝试使用matplotlib和wordcloud库绘制词云图时，遇到了ValueError，提示只支持TrueType字体。错误源于Pillow包的问题。作者首先尝试升级Pillow，但因缺少zlib库而失败。最终，作者通过指定Pillow的一个特定版本（9.2.0）成功避免了错误，完成了词云图的绘制。

首先，俺的需求是‘要用matplotlib 和wordcloud 绘制词云图

import matplotlib.pyplot as plt
from wordcloud import WordCloud
import jieba
text='哇哈技术附件啊离开家'
text=' '.join(jieba.lcut(text))
wordcloud = WordCloud(font_path="D:\\编程\python\\support\\font\\simfang_downyi.com\\simfang_ttf\\simfang.ttf").generate(text)
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis("off")
plt.show()

结果报错：

Building prefix dict from the default dictionary ...

C:\Users\35470\AppData\Local\Temp\jieba.cache

Traceback (most recent call last):

raise ValueError("Only supported for TrueType fonts")   
                                                           
ValueError: Only supported for TrueType fonts

在优快云上搜索若干，都说是Pillow包没更新的原因，github上也是类似：

于是开始想方设法升级Pillow，不过，报错总是出现：“ ERROR: Failed building wheel for Pillow

Failed to build Pillow

ERROR: Could not build wheels for Pillow, which is required to install pyproject.toml-based projects ”

The headers or library files could not be found for zlib,
a required dependency when compiling Pillow from source.
Please see the install instructions at:

最后真是整崩溃了，突然想起来或许可以换其他版本（默认更新的是最新版本），使用以下code查看可以使用的版本：
