5- 在PyCharm中使用Anaconda创建的环境

5.1 查看Conda环境信息

在Anaconda Prompt中通过“conda env list”查看所有环境信息，确认环境所在目录；

注意：通过Conda创建的虚拟环境默认放置envs目录中，例如：“D:\DownLoadFiles\anaconda3\envs\mlcc”

5.2 更改PyCharm的编译器选项

打开Pycharm，然后依次点击File---》Settings---》Project:xxxxx---》Project Interperter---》“齿轮”按钮---》“Add Local...”

在出现页面中，添加Conda环境信息并保存

此时，依次点击File---》Settings---》Project:xxxxx---》Project Interperter---》“齿轮”按钮---》“Show All...”

依次点击File---》Settings---》Project:xxxxx---》Project Interperter，选择相应的环境。

7.1“WARNING: The conda.compat module is deprecated and will be removed in a future release.”

问题现象：

安装Anaconda3后，在Anaconda Prompt执行conda命令， 例如“conda env list”，提示告警信息“WARNING: The conda.compat module is deprecated and will be removed in a future release.”

问题原因：

问题处理方法：

升级conda版本。

7.2 “CondaHTTPError: HTTP 000 CONNECTION FAILED for url”

问题现象

λ conda installjenkinsapi

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP000 CONNECTION FAILED for url

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.'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/win-64'

处理方法

1. 通过“conda search ”命令确认要安装的包是否存在，如果包名称不一致，将报错

2. 修改镜像源的配置， 将用户目录下的.condarc文件中的所有https换成http

如果Windows用户无法直接创建名为.condarc的文件，可先执行“conda config --set show_channel_urls yes”生成该文件之后再修改。

λ cat ~/.condarc

channels:- http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main

- http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free

- http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r

- http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro

- http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/

ssl_verify: falseshow_channel_urls:true

然后运行`conda clean -i`清除索引缓存，保证用的是镜像站提供的索引，重新安装库时会重新下载repo信息。

7.3 在Anaconda的环境下，使用pip安装库报错“SSL: CERTIFICATE_VERIFY_FAILED”

问题现象

λ pip installjenkinsapi

处理方法

国内防火墙的限制，自当镜像源或者`--trusted-host`即可解决。

1. 指定可用的镜像源

”pip install -i “

2. 指定`--trusted-host`

“pip install jenkinsapi --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org”
