build/make/core/main.mk was modified, regenerating... /bin/bash: update_comm_new.sh: 未找到命令

出现这个错误可能是因为系统无法找到名为`update_comm_new.sh`的命令。请确保该命令存在并且在系统的可执行路径中。你可以通过以下步骤来解决这个问题：

1. 确认`update_comm_new.sh`文件是否存在于你的目录中。你可以使用`ls`命令来检查文件是否存在，例如：`ls update_comm_new.sh`。
2. 如果文件存在，确保该文件具有可执行权限。你可以使用`chmod`命令添加可执行权限，例如：`chmod +x update_comm_new.sh`。
3. 如果文件不存在，你需要确认该命令是否正确安装。你可以尝试使用`which`命令查找命令的安装路径，例如：`which update_comm_new.sh`。
4. 如果命令未安装，你需要安装该命令。具体的安装方式取决于你要使用的命令，可能需要通过包管理器或手动下载和编译来安装。

如果问题仍然存在，请提供更多详细信息，以便我能够更好地帮助你解决这个问题。

在pycharm报出这个错误TypeError: Descriptors cannot not be created directly. If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately regenerate your protos, some other poss

ible causes of this error include:

1. Trying to create a descriptor object directly, instead of using a factory function or constructor.
2. Passing incorrect arguments to the factory function or constructor.
3. Using an outdated version of the protobuf library.

To resolve this issue, you can try the following steps:

1. Make sure that you are using the latest version of the protobuf library. You can upgrade to the latest version using pip:

   pip install --upgrade protobuf

2. If you are still encountering the same error, try regenerating your protobuf code using a newer version of protoc:

   protoc --version

If your version of protoc is older than 3.19.0, you will need to update it. You can download the latest version from the official protobuf website: https://developers.google.com/protocol-buffers

3. If neither of the above steps work, check your code for any instances where you are directly creating descriptor objects. Instead, use the appropriate factory function or constructor to create descriptor objects.

DevTools failed to load source map: Could not load content

This error message typically appears in the browser's console when the DevTools (developer tools) cannot load the source map for a specific file. A source map is a file that maps the original source code to the compiled code, making it easier to debug and troubleshoot issues.

There are a few reasons why DevTools may fail to load the source map, such as:

1. The source map file is missing or has been deleted.
2. The path to the source map file is incorrect or has been changed.
3. The source map file is not accessible due to permission issues.
4. The source map file has been corrupted or is invalid.

To resolve this error, you can try the following:

1. Check if the source map file exists in the correct location and has not been deleted.
2. Verify that the path to the source map file is correct and has not been changed.
3. Ensure that the source map file has the proper permissions set.
4. If the source map file is corrupted, try regenerating it.

If none of these solutions work, consider seeking help from a developer or checking the documentation for the specific tool or framework you are using.
