这个错误的原因是，conda的命令行工具变了，你需要做的是，运行 conda init cmd.exe 命令，然后关闭cmd窗口，再打开，就可以使用 conda activate test 激活test虚拟环境了

你这个地方是网络问题，用视频的方法配置一下国内镜像试试，应该可以解决

是网络问题，换一下就好了，但是安装conda 的numpy 遇到了楼下的又是网络问题，尴尬
在c盘用户文件夹下已新建了.condarc文件，把镜像代码保存在文件中，通过网页能访问镜像站的地址，但通过命令conda install numpy无法连接镜像站资源，请老师解惑。错误提示如下：

你这是网络问题，根据错误提示，你的网络总是断断续续的，你看看你的网络情况怎么样再试试，另外注意配置文件的所在文件夹，一定要在你当前用户的用户文件夹下，不要放错了
此问题解决了，是系统的原因，重装系统搞定。
把https 改成http 试试，有时候是服务器不好没响应，过段时间再试试。

配置镜像后安装
问题1：win7配置系统变量（已解决）
分享经验：win7电脑安装conda后，用everything搜“conda.exe”只搜到C:\ProgramData\Miniconda3\pkgs\conda-4.9.2-py38haa95532_0\Scripts文件夹下有conda.exe
配置系统变量中paths值：
不好使，在cmd下运行conda list提示：failed to create process
发现其实在C:\ProgramData\Miniconda3\Scripts文件夹里也有conda.exe，只是everything没搜到。改path值如下后好使了。
若按以下值配置，也不好使，猜测是先调用了C:\ProgramData\Miniconda3\pkgs\conda-4.9.2-py38haa95532_0\Scripts文件夹下不好使的conda.exe导致的
问题2：conda创建的虚拟文件夹路径问题
家里电脑win10系统，装了arcgispro，conda自动创建的文件夹在C:\ProgramData\Miniconda3\envs没找到，
文件夹创建在C:\Program Files\ArcGIS\Pro\bin\Python\envs里了
怎么用conda离线创建虚拟环境？conda创建虚拟环境时是需要连接互联网下包吧？单位电脑是局域网
后面讲矢量编程的时候会说
变量刷新没有用，refreshenv
看上面回复，有问这个问题的
win7的环境变量配置是直接进入环境变量—系统变量—新建吗？跟win10的不太一样
创建的文本文档名称改成“.condarc”时提示“不能没有没有文件名”。
用cmd命令行工具进入目录下，用
新建一个文件吧
可以了，谢谢老师！
之前学了一点Python，用的Pip，这次才了解到Conda。Conda可以管理所有语言编写的包，而Pip只能管理Python编写的包，这么说是不是只使用Conda即可，它完全优于Pip呢？
一定程度上可以这么说，但是有几点注意，一般情况下conda 的python版本都要低于最近的python一个版本，conda用不到最新的版本，另外conda并不是保证百分百适配所有python包，虽然可以几乎忽略不计。最后conda和python的远程包管理网站不一样，有一些包是有差异的，conda的包网站比较注重科学运算等方面，pip的包网站更宽泛一些。
老师，把视频播放页上面加上快进快退按钮，能实现小键盘的左右键可以控制快进和快退，这样听到不懂的时候就可以反复的去听，不用鼠标一致去拖拽时间轴了。会更方便一些
你这个难为我了，实在不行你下载下来用桌面软件看吧，咱们的在线播放器终归功能有限的
