在将pychopg2安装到我的工作计算机中时遇到问题（Windows btw）。由于网络限制，不能选择使用pip，所以我已经学会了如何手动安装软件包，经过一些尝试，它似乎可以正常工作并且安装运行没有错误：

但是我的代码编辑器仍然抱怨“没有名为psychopg2的模块”。我正在使用anaconda3，在安装过程中已添加到路径。看来这可能会引起问题，但我不知道这是否是导致程序包无法识别的原因。另外，当我从cmd运行python时，它说：
Warning:
This Python interpreter is in a conda environment, but the environment has
not been activated. Libraries may fail to load. To activate this environment
please see https://conda.io/activation
但是当我转到环境应该所在的文件夹时，它是空的。因此，我尝试创建一个，但又收到另一个网络错误。我没主意了。
答案 0 :(得分：0)
您正在运行Anaconda解释器而未激活环境。
运行conda activate env_name，其中env_name是您创建的环境，或者base是默认环境。然后，使用conda（首选）或pip在环境中安装软件包，并在环境处于活动状态时运行Python。
