Error failed to build IOS project. We ran “xcodebuild” command but it exited wit
did not change the profile file before NPM run ios is no error. After changing the profile to introduce react and using pod install, the error report is as follows:
error Failed to build iOS project. We ran “xcodebuild” command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app
solution
1. Delete the item dependent package and the yarn cache
rm -rf node_modules & & yarn cache clean
2. Repackage
yarn install
3. Clear React-Native cache
rm -rf ~/.rncache
New folder .rncache
mkdir ~/.rncache
5. Directly run the download script
node_modules/react-native/scripts/ios-install-third-party.sh
6. If the download is completed, run react-native run-ios directly to succeed
7. If the download fails, run the code in 4 repeatedly for more than 20 times before I succeed, or do the following steps
8. The four download links are key, use the tool to download these four files. download link is closely related to React-Native version, please check the file version carefully.
(1) https://github.com/google/glog/archive/v0.3.5.tar.gz
(2) https://github.com/google/double-conversion/archive/v1.1.6.tar.gz
(3) https://github.com/react-native-community/boost-for-react-native/releases/download/v1.63.0-0/boost_1_63_0.tar.gz
(4) https://github.com/facebook/folly/archive/v2018.10.22.00.tar.gz
page open the link to download
9. After downloading, enter directory
open ~ /. Rncache
10. Move the four downloaded files to the directory
11. Run the installation script again, because you are using the local download file, all run quickly
node_modules/react-native/scripts/ios-install-third-party.sh
12. If not successful, continue running node_modules/react-native/scripts/ ix-install – thirdparty. sh until successful
13. The project can run, the first start will be a little slow, patience will wait on the line
react-native run-ios
npm install optipng-bin Failed at the [email protected] postinstall script
as shown in the question, error when installing optipng-bin dependency in the project, screenshot as shown below:
from the error message, it seems to be similar to the Linux system source installation, I thought this problem could not be solved, until I found a way to add a parameter to the installation, –ignore-scripts is ok, as shown below:
is a little hard to believe, but it’s true, it seems to bypass source compilation. A bit of a surprise, a bit of a surprise. I hope it will be helpful to those who encounter this problem.

Solution to GitHub desktop login error: failed to fetch
Today is my first day to use github Desktop. When I try to log in with my account, an error occurs: Failed to fetch. This is so depressing. While I was searching that problem on Baidu, I found some other developers also met that problem, but I found no answer.
Then I searched that problem on Bing with English, I found a similar github issue. Some warm-hearted developer suggested that firewall or DNS problems can result in that kind of error. Then I found this is a network error. It is difficult visit Making in China. So, I runned a vpn, then the problem is solved. So, Check you firewall and network.
today was my first day on the github desktop. An error occurred when I tried to log in using my account: could not get. It’s frustrating. When I searched for this question on Baidu, I found that some other developers had also encountered this question, but I couldn’t find the answer.
then I searched the problem in English on Bing and found a similar github problem. Some avid developers have suggested that a firewall or DNS problem could cause this error. Then I realized it was a network mistake. It’s hard to visit Github in China. So, I ran a VPN and the problem was fixed. So check your firewall and network.

Failed: error connecting to db server: server returned error on SASL authentication step: Authentica
mongdb database can not be backed up after adding user name and password, it has been suggested that the verification failed. Finally found that their database password with a special character reason.
Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.
The solution given on
network is to add — authenticationDatabase, but I still can’t add it.
~ $ mongodump -h 127.0.0.1 --port 27017 --authenticationDatabase manager -u LorettaLei -p LorettaLei$001 -o db
2019-11-26T16:30:21.206+0800 Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.
finally figured out that it might be because I had a special character in my password. I put a backslash before the special character, and it succeeded immediately. I was so clever!
Solve the error in Ubuntu 18.04: called “net usershare info” but it failed: failed to execute child process “net”
1. Problem description
Ubuntu 18.04 suddenly encountered the following error while using:
Called "net usershare info" but it failed: Failed to execute child process “net” (No such file or directory)
The
error comes from Ubuntu nautilus, and the trigger is when nautilus is closed, as shown below:
2. Solution
s1.install samba-common-bin by running the following command from the terminal:
sudo apt install samba-common-bin
if you finish executing S1 and close nautilus with the following error, proceed with S2.
S2. Execute the following command:
sudo mkdir /var/lib/samba/usershares
you can now find that closing nautilus will no longer report an error, and the problem is resolved.

I recently noticed that github users’ profile pictures and images from my posts no longer show up. Then today I found an error message for the title when homeBrew and NVM were installed.
these are installed PNPM error message, can be found that the script needs to pull the code on raw.githubusercontent.com.
Internet search, found that some github domain name DNS resolution is contaminated, causing DNS resolution process can not get the correct IP address through the domain name.
DNS pollution
DNS pollution, interested friends can go to understand.
solution
open https://www.ipaddress.com/ input can’t access the domain name
query can get the correct IP address
is added in the host file of the machine. It is recommended to use switchhosts to facilitate host management of
199.232.68.133 raw.githubusercontent.com 199.232.68.133 user-images.githubusercontent.com
199.232.68.133 avatars2.githubusercontent.com
199.232.68.133 avatars1.githubusercontent.com
add the above several host configuration, the page picture display will be normal, homebrew can also be installed, NVM action is flexible.

Simple Python crawler exercise: News crawling on sohu.com
python crawler: sohu news crawler
python crawler exercise: sohu news crawl
helped a friend write a course design to get the title, time, and body content of the news page.
write very simple, not very complicated knowledge, should be easy to understand.
is the first step to import the libraries we need, including requests for third-party libraries. Remember to install
with PIP
import requests
import re
import os
first get all the HTML code you need from the sohu home page
# 获得搜狐页面的内容
def get_all_url(url):
try:
# 获取总的html内容
html = getHTMLText(url)
return html
except:
print("failed connect")
# 获得html内容，套路内容
def getHTMLText(url):
try:
# requests爬虫的正常操作，访问获得返回
r = requests.get(url)
# 判断是否成功？
r.raise_for_status()
# 改变编码方式，转为UTF-8
r.encoding = r.apparent_encoding
# 返回html正文内容
return r.text
except:
return ''
and then we need to parse out all the hyperlinks in the HTML, so we need to call the re library here.
if you don’t know regular expressions, learn them yourself, and I won’t go into that.
note that all url links are obtained here without analyzing whether the url is a news url. And, of course, there’s the judgment
# 分析内容，获得我需要的链接们
def parsePage(html):
plt = []
try:
# findall函数的意思：（pattern, string），将所有匹配项组成一个列表，并返回该列表
# 匹配符合url链接格式的所有内容
plt = re.findall('http://www\.sohu\.com(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+', html)
except:
print("介个地方出错了")
print(plt)
return plt
here also USES re library to analyze the news title, sending time and news body content. Note that different websites have different HTML idioms. When writing a crawler, it must take some time to analyze the page. Press F12 to view all the HTML code.
since I’m not sure if pictures and the like count as text, I just put in a big chunk of text.
# 正则分析获得时间与标题，嘻嘻
def title_and_time(html):
tat = []
try:
# findall函数的意思：（pattern, string），将所有匹配项组成一个列表，并返回该列表
# 获得时间，若无法匹配就返回空列表
time = re.findall('dateUpdate" content="(.*)" />', html)
# 获得标题，若无法匹配就返回空列表
title = re.findall("title>(.*)</title", html)
# 文章正文内容，若无法匹配就返回空列表
article = re.findall('<article class="article" id="mp-editor">([\s\S]*)</article>', html)
# 三者组成一个列表，传回去嘻嘻
# 若其中有的为空列表，则不占用位置
# 因此如果是正规的新闻页面，tat的长度len应该是3
tat = title + time + article
except:
print("捏个地方出错了")
return tat
and that’s all we need, so I’m going to put all the code out here for your reference.
