            Error: require() of ES modules is not supported when importing node-fetch
            Asked 2022-Mar-28 at 07:04

            I'm creating a program to analyze security camera streams and got stuck on the very first line. At the moment my .js file has nothing but the import of node-fetch and it gives me an error message. What am I doing wrong?

            Use ESM syntax, also use one of these methods before running the file.

            1. specify "type":"module" in package.json
            2. Or use this flag --input-type=module when running the file
            3. Or use .mjs file extension

            Java, Intellij IDEA problem Unrecognized option: --add-opens=jdk.compiler/
            Asked 2022-Mar-26 at 15:23

            Answered 2021-Jul-28 at 07:22

            You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

            So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

            Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

            I have two running emulators but they open together in different tabs and in one single window.

            How to open them in two different window?

            File->Settings->Tools->Emulator, and uncheck Launch in a tool window Then they will open in their own stand alone windows again.



            Flutter Web: Cannot scroll with mouse down (drag) (Flutter 2.5+)
            Asked 2022-Jan-19 at 09:57

            I can confirm this issue happened in flutter above 2.5. Using 2.2.3 is fine. The question becomes why this feature been removed in 2.5 ? And how to enable it in flutter 2.5?

            [Origin Question]

            I'm using SingleChildScrollView on flutter web with desktop browser. Scrolling only works on mouse wheel but not on mouse click (drag). How can I map mouse click to touch and scroll like mobile?

            Flutter change mouse scroll behavior after 2.5. See this for detail.



            Python 3.9.8 fails using Black and importing `typed_ast.ast3`
            Asked 2021-Nov-17 at 08:17

            Since updating to python@3.9.8 we get an error while using Black in our CI pipeline.



            Answered 2021-Nov-17 at 08:17

            The initial error was a failing python Black pipeline. Black failed because it was pinned to an older version which now fails with python3.9.8.

            Updating black to the latest version 21.10b0 fixed the error for me.

            See also typed_ast issue #169:

            For others who may find this in a search, I ran into this problem via black because I had black pinned to an older version. The current version of black appears to no longer use typed-ast and thus won't encounter this issue.


            using the latest typed-ast version >=1.5.0 seem to work as well

            e.g. pip install typed-ast --upgrade



            Cannot update spyder=5.1.5 on new anaconda install
            Asked 2021-Nov-15 at 08:33

            I installed anaconda and spyder came with the installation. Spyder 4.2.5 came with the installation and I got a pop up notification that spyder=5.1.5 is available. I tried

            and gets an error:

            Solving environment: failed with initial frozen solve. Retrying with flexible solve.

            I tried letting it run for more than 8 hours, but I had to cancel it because I got tired.


            conda install anaconda spyder=5.1.5

            and gets another error:

            (Spyder maintainer here) Our regular instructions to update Spyder don't work in this case because there are some incompatible dependencies between Spyder 5.0.5 and 5.1.5.

            To workaround this problem, you need to close Spyder and run the following commands in the Anaconda Prompt (or your system terminal on Linux or macOS):



            After conda update, python kernel crashes when matplotlib is used

            Update 2021-11-06
            • The default pkgs/main channel for conda has reverted to using freetype 2.10.4 for Windows, per main / packages / freetype.
            • If you are still experiencing the issue, use conda list freetype to check the version: freetype != 2.11.0
              • If it is 2.11.0, then change the version per the solution, or conda update --all (providing your default channel isn't changed in the .condarc config file).
            • If this is occurring after installing Anaconda, updating conda or freetype since Oct 27, 2021.
            • Go to the Anaconda prompt and downgrade freetype 2.11.0 in any affected environment.
              • conda install freetype=2.10.4
            • Relevant to any package using matplotlib and any IDE
              • For example, pandas.DataFrame.plot and seaborn
              • Jupyter, Spyder, VSCode, PyCharm, command line.
            • An issue occurs after updating with the most current updates from conda, released Friday, Oct 29.
            • After updating with conda update --all, there's an issue with anything related to matplotlib in any IDE (not just Jupyter).
              • I tested this in JupyterLab, PyCharm, and python from the command prompt.
              • PyCharm: Process finished with exit code -1073741819
              • JupyterLab: kernel just restarts and there are no associated errors or Traceback
              • command prompt: a blank interactive matplotlib window will appear briefly, and then a new command line appears.
            • The issue seems to be with conda update --all in (base), then any plot API that uses matplotlib (e.g. seaborn and pandas.DataFrame.plot) kills the kernel in any environment.
            • I had to reinstall Anaconda, but do not do an update of (base), then my other environments worked.
            • I have not figured out what specifically is causing the issue.
            • I tested the issue with python 3.8.12 and python 3.9.7
            • Current Testing:
              • Following is the conda revision log.
              • Prior to conda update --all this environment was working, but after the updates, plotting with matplotlib crashes the python kernel



            What should happen if one calls `std::exit` in a global object's destructor?

            If std​::​exit is called to end a program during the destruction of an object with static or thread storage duration, the program has undefined behavior.
