error:Error:Spawn failed
bash
err:Error:Spawn failed
今晚在发布文章的时候突然出现了这个问题，昨天还是正常的，今晚就报错了，前前后后尝试了好多办法
解决问题
删除id_rsa、id_rsa.pub、known_hosts
打开C:\Users\Administrator\.ssh路径,删除id_rsa、id_rsa.pub、known_hosts
在bash重新生成rsa文件
bash
>>>ssh-keygen -t rsa
打开github--->setting--->SSH and GPG keys--->New ssh key
打开.ssh路径，将id_rsa.pub的内容复制到新创建的ssh key里面
测试是否连接到github
bash
>>>ssh -T git@github.com
ssh: connect to host github.com port 22: Connection timed out #连接失败
# 如果是出现以下则说明成功，以下的文章就不用看了
The authenticity of host '[ssh.github.com]:443 ([20.205.243.160]:443)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? # 此时在此输入yes回车就行
如果你失败了，接着往下
新建config文件
在config文件输入下面内容
yaml
Host github.com
User *****@gmail.com #登录github的邮箱，这段文字不复制到文件
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Port 443
连接github
bash
>>>ssh -T git@github.com #此时出现以下页面成功啦
The authenticity of host '[ssh.github.com]:443 ([20.205.243.160]:443)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes # 此处输入yes
Warning: Permanently added '[ssh.github.com]:443' (ED25519) to the list of known hosts.
Hi 0000rookie! You've successfully authenticated, but GitHub does not provide shell access.
GitHub部署博客出现404错误
分两种情况
还未修改域名
-
打开
GitHub仓库看文件是否已经上传成功，成功如图。
image-20220814142018037 -
如果仓库是空的，说明你没上传成功。
- 检查
blog文件夹下的_config.yml文件deploy:的配置有没有正确。如下
bashdeploy: type: git repo: git@github.com:0000rookie/github.io.git branch: main- 重新部署到
github仓库。
bashhexo clean #清除缓存文件 db.json 和已生成的静态文件 public hexo g #生成网站静态文件到默认设置的 public 文件夹(hexo generate 的缩写) hexo d #自动生成网站静态文件，并部署到设定的仓库(hexo deploy 的缩写)-
在部署过程中，查看git窗口看有没有报错的地方，如有报错，查看报错内容，如果没有，此时查看
github仓库有没有更新文件。 -
如果还是没看到有更新内容，看看
github分支是不是main，有些同学的分支是master，需要选择分支和部署的分支一致
- 检查
还有可能的错误是hexo安装有文件缺失，要重新安装一遍。打开E:\studyAPP\node_js\node_global路径插件是否成功安装Hexo插件了，如果没成功，那就重新安装一遍。
bash
npm install -g hexo-cli
重装还是不行的话，大概率就是你的Nodejs系统环境没配好，重新回到第四篇配置Nodejs环境。
如果成功安装Hexo插件了。再查看一下blog下的_config.yml文件，deploy有没有设置正确，输入格式有没有正确(每一个小红点都是空格)
如果还是404页面，再检查一下hexo-deployer-git是不是安装成功，重新安装一遍
bash
npm install hexo-deployer-git --save
已修改域名
大多数都是Blog/source/CNAME文件没有命名好或者是域名填写错误
CNAME是没有后缀的文件
如果不清楚该文件是不是有后缀的，可以这样打开选项查看
Hexo使用本地搜索不到内容
使用了hexo-generator-search模块，在浏览器想搜索最近的文章内容，但是发现搜索不到。
其实是浏览器缓存了search.xml文件，清理一下缓存就可以了。如图，可以试着禁用缓存，这样可以保证每次的访问都可以搜索到最新的内容，但同时带来的是加载慢，大流量。
hexo backup失败
发现问题
其中错误重点在于：git config --global --add safe.directory
bash
lilbai518@▒▒С▒▒ MINGW64 /e/Blog
$ hexo b
INFO Validating config
INFO Start backup: git
fatal: detected dubious ownership in repository at 'E:/Blog'

again for more information.

git config --global --add safe.directory E:/Blog
Set the environment variable GIT_TEST_DEBUG_UNSAFE_DIRECTORIES=true and run

INFO Backup done: git
解决问题
根据提示执行该命令
bash
git config --global --add safe.directory E:/Blog
lilbai518@▒▒С▒▒ MINGW64 /e/Blog (master)
执行完后，发现端口多了个(master)标识，说明本地仓库已经没问题了，这样直接执行hexo b 试一下
bash
lilbai518@▒▒С▒▒ MINGW64 /e/Blog (master)
$ hexo b
INFO Validating config

。。。中间省略

and the repository exists.
fatal: 'gitee' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights

还是继续报错，删掉博客根目录下的.git文件夹，然后再执行hexo b，提交成功

} Something's wrong. Maybe you can find the solution here: %s https://hexo.io/docs/troubleshooting.html
分析问题
提示`4000``端口已被占用。尝试其他端口。
有两个方法：
- 换端口
- 杀掉占用的端口，重新启用
4000端口
解决问题
方法一
杀掉4000被占用的端口，让hexo运行4000端口
bash
# 查看4000端口是什么程序占用
>>> netstat -ano | findstr "4000"
# 杀掉4000端口正在运行的程序
>>> taskkill -PID 15868 -F
方法二
在_config.yml修改hexo默认端口，在hexo s 的时候就不是4000端口了
yaml
server:
port: 4001
compress: true
header: true
方法三
指定端口运行，这里指定5000端口运行
bash
hexo server -p 5000
Hexo怎么安装插件
-
打开hexo的根目录
Blog -
输入安装地址(此处我以安装
npm i hexo-algoliasearch测试)bashnpm i hexo-algoliasearch -
安装成功
Hexo怎么卸载插件
-
卸载也是在
Blog打开cmd，输入npm uninstall 插件名 --save即可 -
或者简洁一点
npm un 插件名 --save -
举个例子，我要卸载
hexo-renderer-marked这个插件 -
在cmd输入
bashnpm un hexo-renderer-marked --save
查看全局安装的包
npm list -g --depth 0
查看hexo所有的插件
进入博客根目录
npm list --depth 0

没有可用于预检请求的内容
报错内容
中文报错内容：无法加载响应数据：没有可用于预检请求的内容
英文报错英文：Failed to load response data:No data found for resource with given identifier
但是很奇怪，我在Firefox电脑端访问没问题，Edge电脑端访问就报错，手机端Firefox也报错，Chrome也报错
Hexo使用KaTex中文报错

这种情况的话在 $...$ 中用 \text{} 对中文包裹应该可以解决这个问题，比如 $\text{中文}$ 。另外这样的警告应该不会对渲染造成任何的影响，一定程度上可以忽视。
比如下面例子，中文用\text{}包括住
latex
\text{平均等待时间}=\frac{(57+20+64+80)}{4}=55.25
\\
\text{平均周转时间}=\frac{(0+20+37+57)}{4}=28.5
\\
\text{通常，RR的平均周转时间比SJF长，但响应时间要短一些}
