你可以去蟒蛇餐厅试试。

你会看到(基础)，现在升级pip。 例子:

(base) C:\Users\Tom>cd ..

(base) C:\Users>cd ..

(base) C:\>python -m pip install --upgrade pip
Requirement already up-to-date: pip in g:\anaconda3\lib\site-packages (20.0.2)

(base) C:\>pip -V
pip 20.0.2 from G:\Anaconda3\lib\site-packages\pip (python 3.7)

# Try install
(base) C:\>pip install selenium

这将花费较长的时间，但也将安装或升级Anaconda内部使用的SSL库。继续前进

centos 7:

安装openssl:

sudo yum install openssl-devel

现在进入python目录，在那里我们提取了python tar文件，

运行以下命令

sudo ./configure
sudo make
sudo make install

这将解决centos的问题…

我也有同样的问题，这是因为我改变了环境的文件夹。 我只是移除了env，重新安装了所有东西。

你可以尝试brew链接，它会告诉你正确的说明:

$ brew link openssl --force
Warning: Refusing to link macOS provided/shadowed software: openssl@1.1
If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

For pkg-config to find openssl@1.1 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

如果您已经通过scoop安装了anaconda，并且在conda环境中使用pip时遇到此错误，您可以通过…

将这些添加到路径中

C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Scripts
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Library
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Library\bin

通过scoop安装openssl

scoop install openssl

并从..复制以下dll。\anaconda3\Library\bin到..\anaconda3\ dll

我得到了同样的错误:

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

在《Anaconda》中，我使用了以下命令:

conda install anaconda-navigator
