anaconda安装库时报错：CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/twisted-19.2.0-py37he774522_0.tar.bz2>

在anaconda下安装scrapy库时，报了CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/twisted-19.2.0-py37he774522_0.tar.bz2>这个错误，查找到了大佬的帖子：https://blog.csdn.net/ling_xiobai/article/details/78659981成功安装好了。

具体报错如下：

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.continuum.io/pkgs/main/win-64/repodata.json.bz2>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
ConnectTimeout(MaxRetryError("HTTPSConnectionPool(host='repo.continuum.io', port=443): Max retries exceeded with url: /pkgs/main/win-64/repodata.json.bz2 (Caused by ConnectTimeoutError(<urllib3.connection.VerifiedHTTPSConnection object at 0x00000247EB8CC1D0>, 'Connection to repo.continuum.io timed out.

配置了清华大学的镜像：

(base) C:UsersLenovo>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/

(base) C:Lenovo>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/

(base) C:UsersLenovo>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

(base) C:UsersLenovo>conda config --set show_channel_urls yes

注意是一句一句地执行，并且这个配置过程没有结果输出的（不要以为自己错了）.

最终测试:
