昨天代码正在运行但是当我今天运行我的代码时，会发生以下错误：
runfile('/media/mattes/data1/dataDMattes/Code/Python/PythonProgram/main.py', wdir='/media/mattes/data1/dataDMattes/Code/Python/PythonProgram')
Traceback (most recent call last):

我还尝试重新安装所有内容并再次安装gdal和libgdal，但错误仍然存在。我使用的虚拟环境：
gdal 2.2.4 py36_0 conda-forge
libgdal 2.2.4 hc8d23f9_1 anaconda
嗯，我知道这两个来自不同的来源，但直到昨天一直有效。
我在Ubuntu 16.04中使用Python 3.6.3和Anaconda。
更新
正如我发现的那样，当我使用PyCharm而不是Anaconda时，也会出现同样的错误。在这种情况下，我使用pip命令和预先安装的libgdal下载GDAL。
在这种情况下，这是错误消息：

对于PyCharm，我使用的是Python 3.5.2。
有人有想法吗？
非常感谢！
答案 0 :(得分：0)
如果昨天有效，请尝试查看conda list --revisions -n gmt-python2以查看自此以来发生的变化。
我不认为Anaconda本身来自conda-forge频道的gdal和来自anaconda频道的libgdal。所以它必定发生在某个时刻。
您可以尝试使用其中一个频道强制Conda更新。使用GDAL我绝对更喜欢conda-forge构建，因为它（至少在过去）有更好的工作激活脚本，这些脚本在切换环境时也能正确设置GDAL_DATA环境变量。
conda install conda-forge::gdal=2.2.4 --force --update-dependencies
