"pip install matplotlib":""python setup.py egg_info" failed with error code 1" 安装 matplotlib 时

Question

我是python的新手。 在命令提示符下安装matplotlib时，它抛出以下错误

使用的命令： pip install matplotlib

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Prasanth\AppData\Local\Temp\pip-install-4wpq_qdh\matplotlib\

下面附上命令提示符的屏幕截图。 有人可以请教如何解决这个问题吗？

    Edit setup.cfg to change the build options; suppress output with --quiet.

大多数情况下，这个问题是由于旧版本的 setuptools。 所以你可以用下面的代码升级它：

pip install --upgrade setuptools

并尝试以管理员身份打开您的 CMD。

您也可以通过 Conda 简单地安装您的软件包。 您只需要运行以下其中一项：

conda install -c conda-forge matplotlib
conda install -c conda-forge/label/testing matplotlib
conda install -c conda-forge/label/testing/gcc7 matplotlib
conda install -c conda-forge/label/matplotlib_rc matplotlib
conda install -c conda-forge/label/gcc7 matplotlib
conda install -c conda-forge/label/broken matplotlib
conda install -c conda-forge/label/rc matplotlib
conda install -c conda-forge/label/cf201901 matplotlib
conda install -c conda-forge/label/broken-test matplotlib
