After we solved the problem of could not resolve com.android.tools.build: gradle: 7.0.2, we reported this error in build output
The most direct solution is to download the version of Android SDK build tools in SDK tools. The path is file >settings> Appearance& Behavior> System Settings> Android SDK> SDK Tools. Unfortunately, I couldn’t download it, so I changed the buildtoolsversion in APP/build.gradle to “31.0.2” of all my current 31.0.2 versions
In the project structure, we have also changed everything, but after running, we still report such an error
After I changed the version to 30.0.2, I still have this problem. Obviously, I have this version, but why not? When I checked my SDK tools, I found that 31.0.0 and 30.0.2/28.0.3/27.0.0 are under Android SDK build tools 31
So I guessed whether it could not be found under the file, so I deleted all except the 30.0.2 version I currently use
Close Android studio and open it again. Success
This error occurred in the last step of installing mujoco.
All the previous steps have been obtained, including downloading mjkey, installing VC + + buildtools, downloading mjpro150 and the corresponding version of mujoco py. In many tutorials, it is mentioned that PIP install mujoco py = = 1.50.1.68 should be run at last, so an error appears in the title.
function
pip install -e <path>< path> Is the local mujoco py file directory. The installation was successful.
Attached:
During the first import, the compilation will be performed first, and errors may be reported, such as mujoco and mujoco_Py installed pit code farm home
Vs 2019 is installed, Microsoft Visual C + + 2015 is available, and GPU is not supported, so CUDA installation is skipped, and pip install tensorflow = = 2.1.0 is directly used. The result shows importerror: DLL load failed.
Solution: PIP uninstall tensorflow uninstall tensorflow
pip install tensorflow = = 2.0.0
Problem recurrence:

]);1. Your project should report this problem when compiling after pod install, as shown in the figure below
2. Let’s start with the solution option CD /Users/yixuan/Downloads/bluecollar_ gongdi_ IOS/bluecollar/pods/target support files/pods bluecollar/pods bluecollar resources.sh this file is located in the folder
3. CD to the pods directory where the error is reported, and then execute the command Chmod a + X pods-bluecollar-resources.sh to solve the problem
4. Cocoapods provides a bash script named pods-resources.sh, which will be executed every time the project is compiled to copy various resource files of the third-party library to the target directory.
5. Cocoapods sets all dependencies and parameters at compile time through a file named pods.xcconfig.

In this case, there is no need to reinstall the docker
rename the docker directory under C:\users\administrator\appdata\roaming (this directory depends on where docker is installed on everyone’s computer. My directory is: C:\users\ZK\appdata\roaming) to docker_Backup (actually delete and backup)
reason: start docker for windows.exe , which prompts that docker is not started. Click to start docker, and everything is restored as before. The original container reason is that my previous docker image installation directory is on disk e, and the application is automatically installed on the default Disk C after upgrading
Solution: docker generates a file dockerdesktop.vhdx , move this file to the newly installed directory or set {setting ---- > resources ---- > advanced ---- > disk image location} in the dockerdesktop.vhdx application (Note: a new directory will be generated. I change the permission, delete and replace it) remember to back up
Result: both the original vhdx file and the image are.

When using NPM, the following suddenly appears: although it doesn’t seem to affect the use, it’s annoying to come out every time
Solution:
first, enter the corresponding folder. According to the above figure, my folder is C:\users\38646.config
you can find another folder. After entering a JSON
use the editing tool to open the JSON file and change the value of optoute to true
Solution: failed to load ApplicationContext
Generally, it can be solved according to the following steps
Step 1: check the annotation
check whether there are the following annotations
@RunWith(SpringRunner.class)
@SpringBootTestIf not, add dependencies and add comments
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.13</version>
<scope>test</scope>
</dependency>Step 2: check the package name
check whether the package name or package path in the XML file is correct, because beans are configured through XML. If they cannot be loaded, they are usually injected into the XML file in the container.
Example:
Step 3: check the encoding format
setting
