pip命令使用详解「建议收藏」

大家好，我们又见面了，我是你们的老朋友全栈君。

pip工具在功能上类似于CentOS系统中的yum命令，主要用于安装和维护Python包。

在Windows系统中，pip工具通常已经预装，但由于其安装目录没有添加到环境变量Path中，导致命令无法被系统识别。

只需将Python安装目录下的scripts文件夹添加到环境变量Path中即可解决这个问题。

在Linux系统中，可以通过以下命令完成pip的安装：

# wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
# python get-pip.py

使用pip安装包的命令如下：

pip install package_name

查看已安装包的详细信息，可以使用以下命令：

pip show --files package_name

要检查哪些包需要更新，可以执行：

pip list --outdated

升级包的命令如下：

pip install --upgrade package_name

卸载包的命令如下：

pip uninstall package_name

使用pip --help命令可以查看pip的帮助手册：

# pip --help
