1. 手动操作
1.1. 显示模块
1
|
pip list
|
1.2. 显示过期模块
1
|
pip list - - outdated
|
1.3. 安装模块
1
|
pip install xxx
|
1.4. 升级模块
1
|
pip install - - upgrade xxx
|
2. 自动操作
手动敲命令升级有点儿麻烦(特别是需要更新的模块比较多时),而我们完全可以用代码简单地实现全自动升级。
代码可以至GitHub下载,也可以复制本文中的代码:

#print(outdatelist)

print (i,end = '')
i = i[:i.find( ' ' )]
updatelist.append(i)
#print(' ', i, len(i))
updatelist = updatelist[ 2 :]
#print(updatelist)
c = 1
total = len (updatelist)
if updatelist :
for x in updatelist:
print ( ' ' , c, '/' , total, ' upgrading ' , x, sep = '')
c + = 1
tempcmd = "pip install --upgrade " + x
os.system(tempcmd)
print ( "所有模块都已更新完毕!!" )
print ( 'All modules have been updated.' )
else :
print ( "没有模块需要更新!!" )
print ( 'All modules is updated.' )
print ( '请按回车键以退出程序。' )
print ( 'Press enter key to quit.' )

Windows平台下可以运行下面的脚本,该脚本会自动获取管理员权限并进行更新(安装在C盘或者其他一些特殊的目录下可能需要管理员权限才能更新)。
autoUpgradePythonModules.bat:

@echo off
