这个错误提示显示找不到 `/tmp/pip-l64mmjzv-build/setup.py` 这个文件。这可能是由于缺少依赖项或网络问题导致的。你可以尝试以下解决方法：

1. 确认是否已经安装了 `setuptools` 和 `wheel` 这两个依赖项，如果没有，请先安装：

sudo pip3 install setuptools wheel

2. 检查你的网络连接是否正常，可以尝试使用 `ping` 命令测试一下：

ping www.google.com

如果无法连接，可能需要检查你的网络设置。

3. 如果以上两个方法都没能解决问题，可以尝试清除 pip 的缓存，并重新安装：

sudo pip3 cache purge
sudo pip3 install chardet-5.1.0.tar.gz

希望这些方法能帮助你解决问题。另外，建议在使用 `sudo pip` 安装包时加上 `-H` 参数，以避免出现权限问题：

sudo -H pip3 install package_name
