4. 接下来就可以正常使用pycharm
image
image
5.在settings中设置. File--->Settings
设置字体大小
image
设置背景色，选好之后，不要忘记点击OK哦！
image
最终，效果如下。字体适中，背景色比较漂亮，而且不会伤害眼睛。哈哈，本人非常满意！你也可以根据自身情况进行选择啦！
image
需要什么库，直接在终端使用pip3命令下载即可
image
至此，Python和Pycharm都已经安装好。
永久激活pycharm
step1:下载jar包： 此jar包的目的就是让截获截止时间并骗过pycharm;
step2:下载完毕后， 将其放入pycharm在你本地的安装目录bin下。并且修改两个以 vmoptions为结尾的启动文件如图所示:
image
image
并且在两个文件后追加
-javaagent:E:\software\PyCharm 2019.1\bin\JetbrainsCrack-2.6.10-release-enc.jar
注意：自己的安装目录
step3:重启pycharm 如需激活码，可填写

pip
安装python包基本都是使用pip
pip --help
pip使用实例
搜索包;
$ pip search redis
安装redis包;
$ pip install redis
安装指定版本;
$ pip install redis==2.10.5
升级包;
$ pip install --upgrade pip
查看redis驱动信息;
$ pip show redis
卸载redis驱动;
$ pip uninstall redis
列出所有安装包;
$ pip list
列出待更新包;
$ pip list --outdate
这里特别关注一下install命令，查看一下帮助：pip help install
$ pip help install
Usage:
pip install [options] [package-index-options] ...
pip install [options] -r [package-index-options] ...
pip install [options] [-e] ...
pip install [options] [-e] ...
pip install [options] ...
........
下面说几个重要参数：
升级一个软件包
$ pip install --upgrade pip
批量安装软件包，使用-r指定一个文本，在文本中指定软件包名称，也可以指定软件包版本。
$ pip install -r requirements.txt
修改pip的镜像地址。
$ pip install -i https://mirrors.aliyun.com/pypi/simple/ redis
由于某些不可抗因素，Python官方的包在国内有时无法访问或出现网络不稳定现象。为了解决这个问题就需要将Pip中自带的源地址修改为镜像地址。
目前收集的比较好的镜像地址有：
http://pypi.douban.com/simple/
http://mirrors.aliyun.com/pypi/simple/
如果不适用加密方式访问的话就需要指定信任此主机。
$ pip install --trusted-host mirrors.aliyun.com -i http://mirrors.aliyun.com/pypi/simple/ redis
PIP配置文件
另外，PIP支持配置文件pip.conf，可以创建在/etc/pip.conf，或者在~/.pip/pip.conf。
$ cat /etc/pip.conf
[global]
timeout = 60
trusted-host=mirrors.aliyun.com
index-url=http://mirrors.aliyun.com/pypi/simple/
更多的参数使用可以看pip help [command]。
问题：在PyCharm写代码时，光标变粗了，并且按退格键会删除编写的内容。
原因：光标进入了改写状态。
解决方法：按一下鼠标Insert键就好了。
