一般公司的服務器都是和外網隔離的，這個如果沒有內部pip源的話，想要安裝python的模塊就需要去python官網一個一個下載依賴模塊的包，然后逐個安裝，這樣做非常耗時間。
我們今天用的辦法就是現在我們能夠連接公網的linux機器上面先使用pip命令安裝好我們需要的python模塊。然后再將需要的模塊一鍵下載並拷貝到服務器上一鍵安裝。步驟如下：
前提條件：
如果服務器是linux的，我們就需要一個能連公網的linux，不能使用windows是因為，有很多模塊linux和windows兩個平台不是共用的，在安裝的時候會報錯。
步驟：
1、在能連接公網的linux機器上使用pip命令安裝好需要的模塊。（pip安裝的好處是：會自動幫你把依賴模塊安裝好）
pip3 install -i https://mirrors.aliyun.com/pypi/simple/ sh pip3 install -i https://mirrors.aliyun.com/pypi/simple/ docker-py pip3 install -i https://mirrors.aliyun.com/pypi/simple/ fabric pip3 install -i https://mirrors.aliyun.com/pypi/simple/ paramiko pip3 install -i https://mirrors.aliyun.com/pypi/simple/ psutil pip3 install -i https://mirrors.aliyun.com/pypi/simple/ PyMySQL pip3 install -i https://mirrors.aliyun.com/pypi/simple/ redis pip3 install -i https://mirrors.aliyun.com/pypi/simple/ requests pip3 install -i https://mirrors.aliyun.com/pypi/simple/ selenium pip3 install -i https://mirrors.aliyun.com/pypi/simple/ SQLAlchemy pip3 install -i https://mirrors.aliyun.com/pypi/simple/ tornado pip3 install -i https://mirrors.aliyun.com/pypi/simple/ xlrd pip3 install -i https://mirrors.aliyun.com/pypi/simple/ xlwt pip3 install -i https://mirrors.aliyun.com/pypi/simple/ xmltodict pip3 install -i https://mirrors.aliyun.com/pypi/simple/ celery pip3 install -i https://mirrors.aliyun.com/pypi/simple/ celery-flower
2、然后在能連接公網的機器上執行pip freeze>python3_module.txt，這樣就可以將你之前安裝的模塊列表導出來
3、列表導出來以后就需要根據這個列表去把模塊的代碼文件從公網下載下來，執行mkdir python3_package && pip3 download -r python3_modules.txt -d python3_packages/ -i https://mirrors.aliyun.com/pypi/simple/ ，這里我們使用了阿里的源，這樣下載的速度會快很多
4、將下載完的文件夾打包，mv python3_modules.txt python3_packages/ && tar -czf python3_packages.tar.gz python3_packages，然后將打包完的文件上傳到服務器上解壓，tar -xzf python3_packages.tar.gz。
5、在服務器上安裝我們的模塊（前提需要安裝和能連接公網的linux機器版本相同的python），cd python3_packages && /opt/samp/venv/python3/bin/pip3 install --no-index --find-links=file:. -r python3_modules.txt，等待安裝完成即可，這樣可以避免讓人奔潰的依賴模塊一個一個安裝問題。
