如何解決 Pycharm 沒法使用 Anaconda 2018.12 建立Conda 環境問題
最新補充說明：https://mirror.tuna.tsinghua.edu.cn/news/close-anaconda-service/html
首先說明致使該問題緣由是缺乏 openssl 支持，解決方法是添加 openssl 環境變量 或者不使用 HTTPS 。tips: python 大部分安裝源已啓用https鏈接方式。node
本文 Python 版本爲3.6.8。其餘使用方法版本相似。python
PS C:\Windows\system32> python Python 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> >>> exit() PS C:\Windows\system32>
Pycharm 社區版 版本爲2019.1。git
本文使用 Ananonda 版本爲2018.12，操做系統爲 Windows 10，其餘系統相似故障也能夠使用類本方法。github
首先介紹修改系統變量方法。添加openssl.exe到環境變量。web
#添加anaconda 安裝目錄openssl.exe文件夾 C:\ProgramData\Anaconda3\Library\bin
本文已經使用清華大學 Conda 安裝源，具體配置請看教程。 Pycharm 建立Conda 環境具體操做步驟爲 File - Settings- Project:[項目名稱] - Project Interpreter [齒輪圖標] -Add - Conda Interpreter ，點擊OK按鈕。編程
出現錯誤以下圖所示：json
錯誤信息以下：windows

Google一番後嘗試安裝OpenSSL Windows 64位版本，安裝到默認目錄，推薦到OpenSSL官方網站下載源代碼自行編譯安裝（須要必定編程基礎）。本文參考GitHub教程連接 ，安裝完畢openssl同時須要將安裝目錄添加到環境變量path。

所有操做完成後建立Conda環境正常。以下圖所示
安裝和升級軟件包正常。
