### flutter换源 ###

使用环境变量:`PUB_HOSTED_URL` `FLUTTER_STORAGE_BASE_URL`，

upgrade出问题时可能会提示设置`FLUTTER_GIT_URL`变量。

flutter中国

PUB_HOSTED_URL=https://pub.flutter-io.cn
    FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
    FLUTTER_GIT_URL=https://github.com/flutter/flutter.git
    
    
    或者
    
    
    FLUTTER_STORAGE_BASE_URL=https://mirrors.tuna.tsinghua.edu.cn/flutter
    PUB_HOSTED_URL=https://mirrors.tuna.tsinghua.edu.cn/dart-pub
    FLUTTER_GIT_URL=https://mirrors.tuna.tsinghua.edu.cn/git/flutter-sdk.git

更新命令：

flutter upgrade

注：更换环境变量后 重启 或 注销用户后生效。

### gradle ###

文件：build.gradle

highlighter- Dart

// 阿里源
    maven { url 'https://maven.aliyun.com/repository/google' }
    maven { url 'https://maven.aliyun.com/repository/jcenter' }
    maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }

### Python换源 ###

### Anacoda换源 ###

两种方法：

#### 使用命令 ####

安装后，打开命令行工具，使用如下命令

highlighter- Dart

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
    conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
    # 设置搜索时显示通道地址
    conda config --set show_channel_urls yes

#### 修改文件 ####

在个人用户文件夹（一般都在C盘，用户文件夹下你用户名命名的一个文件夹），修改`.condarc`文件,该成如下内容：

highlighter- Dart

channels:
      - defaults
    show_channel_urls: true
    default_channels:
      - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
      - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
      - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
    custom_channels:
      conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      msys2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      bioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      menpo: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      pytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
      simpleitk: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

运行`conda clean -i`清除索引缓存，保证用的是镜像站提供的索引。

### Linux换源 ###

#### Kali换源 ####

修改：/etc/apt/sources.list 文件，新增如下内容：

shell

#阿里云
    deb http://mirrors.aliyun.com/kali kali-rolling main non-free contrib
    deb-src http://mirrors.aliyun.com/kali kali-rolling main non-free contrib
    
    #清华大学
    deb http://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main contrib non-free
    deb-src https://mirrors.tuna.tsinghua.edu.cn/kali kali-rolling main contrib non-free
    
    #浙江大学
    deb http://mirrors.zju.edu.cn/kali kali-rolling main contrib non-free
    deb-src http://mirrors.zju.edu.cn/kali kali-rolling main contrib non-free

更新命令：

highlighter- Dart

apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y

#### Ubuntu换源 ####

修改 etc/apt/sources.list 内容，添加以下内容：

highlighter- Dart

# 阿里云源
    deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
    
    deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
    
    deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
    
    deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
    
    deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

更新命令：

highlighter- Dart

sudo apt-get update

### npm换源 ###

淘宝npm：[http://registry.npm.taobao.org][http_registry.npm.taobao.org]  
淘宝新npm源：[https://registry.npmmirror.com/][https_registry.npmmirror.com]  
淘宝npm web站：[https://npmmirror.com/][https_npmmirror.com]

#### 永久使用： ####

npm config set registry https://registry.npmmirror.com/
    # 验证
    npm config get registry

#### 使用nrm ####

全局安装nrm

npm install -g nrm

然后就可以使用 `nrm ls`查看可以使用的镜像源：

使用`nrm use`就能切换源：

#### 使用cnpm ####

npm install -g cnpm --registry=https://registry.npmmirror.com

#### 临时一用 ####

npm --registry https://registry.npmmirror.com install express
