The reason is that the configuration idea memory setting is too large, and it is invalid to modify the idea64.exe.vmoptions in the installation directory
The solution is to open the C disk, user, user name, intellijidea, 018.3, config, idea64.exe, vmoptions file and modify it
Invalid idea to modify the file in the installation directory

That is, the database server was not installed successfully
at first, I thought that the previous MySQL was not unloaded completely. I also found many ways on the Internet, but they couldn’t work. Later, I tried many times and found a way in a post.

you need to upgrade a plug-in, Visual C + + 2013 and Visual C + + redistributable packages
and use 32-bit Visual C + + redistributable packages for visual studio 2013!!! Note that it’s 32-bit. Even if your computer is 64 bit

I have a little problem today. Come here to share and record:
To solve the problem of authentication failed for ‘http:// * * *. Git’ in the pull project times, let’s share two solutions:
In the case of GIT permission and account password, the reason for this problem is the wrong user name and password
Solution 1:
reset the user name and password as follows:
Set Username
git config --global user.name test1
Set Password
git config --global user.password 123456
After setting, you can use git clone command or git fetch command to pull the project again.
Solution 2:
1) input the following command
git config --system --unset credential.helper
2) Pull the project through git clone or git fetch command, and re-enter the user name and password to successfully pull the project.
2. When installation failed appears on Xiaomi mobile phone
Solution: just turn off the MIUI optimization option in the developer options, and some computers need to turn on the option of installing app through USB.
3. “Install” appears_ FAILED_ UPDATE_ INCOMPATIBLE ”
Solution: maybe it’s because it’s not unloaded completely. You can solve it by the following methods:
settings-> applications-> mange
applications-> select the application-> Select “unistall”. Set/data/system/ packages.xml Delete the relevant information of the app in, and then install it again, because after ADB install, it will packages.xml Add the corresponding program information in.
4. Other situations can be solved by deleting the build folder and then cleaning and building project again.
