配置指南中：安装好Scoop后安装三个软件包，运行其中的
scoop update
系统显示：Scoop uses Git to update itself. Run 'scoop install git' and try again.
于是运行scoop install git，系统自己安装了半个多小时。
最后显示操作超时。

请问该如何处理？

系统为：Windows7 32位系统
下载并安装 Windows Management Framework 5.x 重启电脑后，在命令行界面输入 powershell ↩︎，注意到命令行界面的行首提示信息出现了 PS 字样；
在命令行界面输入 $PSVersionTable.PSVersion.Major ↩︎。
提示：
Windows PowerShell 被终止，返回以下错误:
Method not found: 'System.Threading.Tasks.Task System.Threading.Tasks.Task.Run(
System.Action)'.
请问：这是什么原因啊？应该如何解决呢？

你好！
hello.py 存在 thisPC > MY ROOM (D:) 下面。不知道是不是这个原因ConEmu 不能运行。
谢谢！

安装 Jupyter Lab 环境时，在命令行界面运行 pip install -U pip，会出现 Program 'pip.exe' failed to run:指定的可执行文件不是此操作系统平台的有效应用程序 的报警。
尝试过的解决方法：
重新安装pip
在命令行界面运行了如下指令：
python -m ensurepip
python -m pip install --upgrade pip
仍然出现该问题。
将此问题记录在这。

老师好。
scoop之前已经成功安装，并安装好了3个软件，但是进入到第二课，准备复制自己页面的链接，运行git clone 链接 时显示出错。
截图如下：

感谢！

逻辑运算操作符，前面一行
类似的还有 -= *= /= %= **= //
少了一个 =号，建议修改如下：
类似的还有 -= *= /= %= **= //=

具体如图，搜了搜，没找到相应的解决办法

git 是我单独安装的，scoop git 安装不成功。

老师您好，我按照教程里在jupyter写入代码

例如

tpye (42)

然后按使用“crtl + enter "执行代码，代码没有反应。

而在mac里的terminal里打开Python执行是正常的。会显示

type(42)
<class 'int'>

scoop list 中
openssh 7.6p1failed 失败

我重新安装后，显示已经安装完成

安装过程中，提示fatal: unable to access 'https://github.com/Homebrew/brew/': LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54

请问怎么解决

很感谢老师提供这样的一个学习平台。
但有一个建议，在学习的文档里如果可以加上安装成功后的一个载图，
那新人就知道在自己当前的环境下到底是安装成功了还是不成功，有一些问题在终端下面显示出来的英文和代码真心不知道是什么！希望可以改进，定会帮到不少新手。

*** Please tell me who you are.

Run

git config --global user.email "[email protected]"
git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'Administrator@WIN7-20190908PC.(none)')

如何设置 git，

OS X系统打开Code显示“Something went wrong"，reload很多次都不管用。
公司和家的网络都会这样，开了科学上网走全局也会这样。

老师，您好。
在运行 python -m pip install --upgrade pip 出现如下错误，因为之前安装过AMESinm15这个软件，后面删除了，但是这里显示路径还在，这个怎么解决呢？

问题依然存在，请问该如何解决？谢谢。

建立跟踪以后，git commit时显示“终止提交因为提交说明为空。”
代码如下：

xman-2:learn-git xman$ git status
位于分支 master

尚无提交

未跟踪的文件:
（使用 "git add <文件>..." 以包含要提交的内容）
README.md

提交为空，但是存在尚未跟踪的文件（使用 "git add" 建立跟踪）
xman-2:learn-git xman$ git add README.md
xman-2:learn-git xman$ git status
位于分支 master

尚无提交

要提交的变更：
（使用 "git rm --cached <文件>..." 以取消暂存）
新文件： README.md

xman-2:learn-git xman$ git commit
终止提交因为提交说明为空。

按照这三个步骤来的
scoop bucket add versions
scoop update
scoop install python37
版本就是windows10，但是还是安装不了

运行scoop update和安装三个软件包情况截图如下：

老师您好，
提示是这样的
print(f'4 + 9 = {4 + 9}')
^
SyntaxError: invalid syntax
后面那个单引号错误，从教程直接复制过来代码也是这样的。

你好！
code . 运行出错。

运行到在终端输入：sudo xcodebuild -license accept后，password后面的密码无法输入，就是输入字母终端没有反应。盲输入之后回车显示tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance。请问怎么解决？

过程如下：
PS C:\Users\L> scoop update

这是报错的最后一段，整个报错非常长。

Win10 64位
pip也已成功安装：

推测出现这个问题可能有两个原因：

1.我安装的是Python3.8。
之后想要换成Python37，但是卸载的时候出现了问题：

2.之前的操作误将环境变量里的path清空，这是添加一部分path后的结果：

scoop会默认之前安装的python

不懂安装Jupyter Lab是直接这样运行安装吗？

在按照命令进行环境设置时候，出现几十行代码，有一半白色，一半红色，最后一行的代码是这个
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full comma

运行scoop install python37。出现couldn't find manifest for python37.
请问李老师怎么解决？

电脑配置

安装 Scoop成功

运行 scoop bucket add versions、scoop update、scoop install busybox git python37时出错

将代码中的 python37改为python可以安装python3.8

Warning: Unbrewed dylibs were found in /usr/local/lib.

安装好 Scoop 之后我们建议立刻安装三个软件包，运行：

scoop bucket add versions
scoop update
scoop install busybox git python37

此安装包运行不了

是这样的，进行到scoop install busybox git python37这步时，出现couldn't find manifast for 'busybox'

然后看之前的issues和老师指导进行scoop update 再scoop search busybox 时出现下图情况。
