pip 安装第三方库时各种报错It is a distutils installed project and thus we cannot accurately determine

主要是由于网络原因，国外镜像常通过https，连接失败导致，先说结论：

通过命令指定下载地址，

一、https网络问题

**pip install -i http://mirrors.aliyun.com/pypi/simple/ pyecharts --trusted-host mirrors.aliyun.com  **

**同时加上版本，还可以卸载之前的版本，安装指定的版本**

**pip install -i http://mirrors.aliyun.com/pypi/simple/ pyecharts==0.1.9.4 --trusted-host mirrors.aliyun.com  **

试过的方法，均未解决，可能是我的环境问题，待以后验证：

1、全局取消证书验证

import ssl
    ssl._create_default_https_context = ssl._create_unverified_context

2、修改配置

C:\\Users\\xx\\.condarc中添加

channels:  
  - http://mirrors.aliyun.com/pypi/simple/  
  - https://pypi.tuna.tsinghua.edu.cn/simple/  
show\_channel\_urls: true  
3、发请求时将验证失效

\\Lib\\site-packages\\pip-19.1.1-py3.6.egg\\pip\\\_vendor\\requests\\adapters.py

def send(self, request, stream=False, timeout=None, verify=True, cert=None, proxies=None):

下插入

verify=False

或者升级到新版本

Python3 -m pip install --upgrade pip

### 二、It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial ###

如果确信没问题，可以在pip命令后加上--ignore-installed表示忽略已经安装的库

如下：

pip install -i [http://mirrors.aliyun.com/pypi/simple/][http_mirrors.aliyun.com_pypi_simple] virtualenv --trusted-host mirrors.aliyun.com  --ignore-installed
