在安装过程中，有@小其其格的帖子帮助，刚开始一切比较顺利，当安装cartopy时按部就班下载最新版的Cartopy-0.17.0
下载网址：https://github.com/SciTools/cartopy/releases
当使用方法安装时：python setup.py install
出现问题：

在网上搜索和友人帮助下发现：采用以下安装方式将cartopy所需要的库也可以一起安装好
conda install -c conda-forge cartopy
https://scitools.org.uk/cartopy/docs/latest/installing.html#installing

等cartopy和其他依赖的库都安装以后，开始调试PPI和PPI.VCS，居然有出现了问题了，提示如下：
Traceback (most recent call last):
& nbsp; File "ppi.py", line 56, in <module>
& nbsp;   liner = fig.geoax.gridlines(draw_labels=True,linewidth=2, color='gray', alpha=0.5, linestyle='--')
& nbsp; File "C:\ProgramData\Anaconda3\lib\site-packages\cartopy\mpl\geoaxes.py", line 1224, in gridlines

& nbsp;   'supported.'.format(prj=self.axes.projection))
TypeError: Cannot label gridlines on a AzimuthalEquidistant plot.  Only PlateCarree and Mercator plots are currently supported.
当时心情，那叫一个奔溃啊

赶紧上网搜和请教大侠，网上发帖子提问，Anaconda3也重新安装一篇，还是这样。
网上帖子也给搜出来了，这个问题存在很长时间了，各位大侠各显神通，出了各种主义，具体见：https://github.com/SciTools/cartopy/issues/881
后来有一篇帖子中看到了希望：https://github.com/SciTools/cartopy/pull/1089

于是到：https://github.com/SciTools/Cartopy
选择：codes-->clone or download-->下载 cartopy-master.zip-->解压-->将lib/cartopy/mpi里面的py文件复制到已安装好的库文件里面
我的是：C:\ProgramData\Anaconda3\pkgs\cartopy-0.17.0-py37h814cdbc_1004\Lib\site-packages\cartopy\mpl

测试PPI.VCS.py
这次成功了，上图

多谢楼主，学习了！！！

多谢！我遇到的问题跟楼主的很像，也都照着一步步解决了，但是现在做了“将lib/cartopy/mpi里面的py文件复制到已安装好的库文件里面”以后执行程序出现下面的问题，请问楼主怎么改错呀：

Traceback (most recent call last):
  File "C:/liuming/20190704-人工影响天气指挥作业系统/PyCINRAD-master/test3.py", line 4, in <module>

    return subplot(111, **kwargs)

    import cartopy.mpl.contour

从网上查了资料，我用下面的程序测试cartopy，发现是一样的问题，但是mpl里的我都替换了啊
import matplotlib.pyplot as plt
import cartopy.crs as ccrs
# set projection
ax = plt.axes(projection=ccrs.Robinson(central_longitude=150))
# plot coastlines & gridlines
ax.coastlines()
ax.gridlines(linestyle='--')
# show figure
plt.show()

执行后报错：

  File "C:/liuming/20190704-人工影响天气指挥作业系统/PyCINRAD-master/test3.py", line 4, in <module>
    ax = plt.axes(projection=ccrs.Robinson(central_longitude=150))

问大佬们一个问题。
在安装cartopy-master之前，是不是必须先安装 proj啊。我在安装的时候，提示一句话“Proj 4.9.0 must be installed.”

独孤酒见

另外一个模块（Metpy）安装的问题：
Metpy安装完后出现，Finished processing dependencies for MetPy==0+unknown。

这个是什么意思，看起来安装挺顺畅的。但是conda list里面也看不到这个模块，说明应该没装上。

改用conda install Metpy。提示：
PackagesNotFoundError: The following packages are not available from current channels:

  - metpy

Current channels:

  - https://repo.anaconda.com/pkgs/main/win-64
  - https://repo.anaconda.com/pkgs/main/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

是不是说到  https://anaconda.org    这个地方着metpy模块啊。

问的问题让大家见笑了，实在是不熟悉，但是又想要玩python

多谢各位高人。

Cartopy 直接用conda install 安装

Cartopy 直接用conda install 安装

嗯哪，后来用这个方法装，之后就没有提示问题，list中也能看到有这个模块了。
现在就Metpy模块了，python装法和conda装法都应该没装上，list中没有显示。现在还在找问题。您知道是啥原因吗？我在您的楼上提了这个问题了。
