我已经尝试并再次尝试正确安装 Pycharm 的软件包。我对 Python2.7 和 Python3 都使用了 pip，并且我尝试使用 tar 文件。但是 Pycharm 并没有检测到这些模块，即使它们在 Pycharm 之外工作。我该怎么办？
我正在尝试创建一个调度程序。基本上，我希望它的工作方式是您可以选择一个选项来从您的日程安排中添加或删除一个项目，或者查看您今天的日程安排。当您选择添加一个项目时，您向它提供信息，并将其保存到一个文本文件中。我想这样做，以便当您查看日程安排时，它会打印与今天日期相对应的任何行。有没有办法做到这一点？
我想为自定义命令添加选项。我通过将 .sh 文档放入 /bin 来创建我的命令。是否可以在我的代码中添加“-x”选项？（即自定义命令-c）
我有一个 Realtek 互联网棒，我做了很多恶作剧来安装它，它运行得非常好。但是，每次我重新启动计算机时，它都会自动尝试连接 Lite-On 以太网。即使我手动将其关闭，它似乎也随机尝试重新打开 Lite-On 以太网。当然，它无法连接，因为我的电脑没有插入以太网电缆，所以它不断发送“Lite-On 以太网连接失败”的消息，真的很烦人。有没有办法让它自动关闭？

我查找了如何在桌面上创建网站快捷方式，我不断得到很多不同的方法，但都不起作用。
我无法将 url 拖放到桌面文件夹以创建快捷方式。它只是给我“不支持拖放。使用了无效的拖动类型。
我无法创建 .desktop 或 .sh 文件来创建链接。当我完成这些文件并赋予它们执行权限时，它什么也不做——它们不打开任何窗口。
谁能解释发生了什么，或者如何用不同的方法来做？
编辑：我正在使用 20.04，我正在尝试使用 chrome 创建一个快捷方式（我更喜欢 Chrome 到 Firefox）。
因此，我计划尽快获得 SSD 卡并将其用作启动驱动器，因为我听说这可以使您的计算机启动速度更快。我还想尝试将我的旧硬盘作为辅助存储驱动器。有人可以向我推荐一个好的程序来将引导数据传输到 SDD 上吗？
编辑：我想尝试保留当前安装的 Ubuntu，然后将其移至新的 SSD 卡。
我的电脑很旧，使用 DDR2，最多 8 Gigs 的 RAM。我最近用足够的 RAM 更换了计算机中的两个 RAM 盒以使其最大化。但是，就在不久前，我尝试运行 Memtest，它甚至在完成第一次通过的 1% 之前就冻结了。RAM 在普通计算机上运行良好，并且被 Memtest 检测到，但它不会继续，我必须将其关闭并再次打开才能退出 Memtest（esc 不起作用）。有人知道发生了什么吗？
我最近在一台相当旧的计算机上安装了 Ubuntu，试图赋予它新的生命。过了一会儿，它开始经常冻结，无论何时冻结，我都必须进行硬重启。可能只是因为它是一台非常旧的计算机，但我想知道是否有什么办法可以解决这个问题。
这台计算机是 Optiplex 755，至少有 5 年的历史，可能更老。它安装了 ubuntu 20.04。这是我得到的规格

所以，我有一本关于 Python 的书，它要我从这个网站下载 python shell： www.python.org/downloads/source
我不知道怎么做。有人可以帮忙吗？
所以，我是 Ubuntu 20.04 的新用户，我一直在尝试弄清楚如何制作自己的命令。我一直在尝试使用一系列 if-then 语句来创建一个命令，以弄清楚它们是如何工作的，但我一直遇到同样的错误。这是代码：
echo "Would you like to see the secret? (Y/N)"
read AFFIRM
if [$AFFIRM == Y]; then
echo "Alright, but first I need to ask a few questions. Ready? (Y/N)"
read AFFIRM2
if [$AFFIRM2 == Y]; then
echo "Great. First, what is the name of this computer?"
read COMNAME
if [$COMNAME == thesynthetichuman -o $COMNAME == Computer X]; then
echo "Correct! Next question: What was the name of the first user on this computer?
read USERNAME
if [$USERNAME == synthetichuman]; then
echo "Correct again! Last question: What is your favorite color?"
read FAVCOLOR
echo $FAVCOLOR >> " eh? Nice. Here is the secret!

我很困惑。EOF 错误出现在看似随机的行上，语法错误无论如何都会出现。我不明白如何修复错误，到目前为止我所有的谷歌搜索都是徒劳的。有人可以帮忙吗？
