Hi,
the only way for me to get around this was to disable the Windows 10
built-in OpenSSH Client, via Windows Features.
After that minishift used its internal ssh client and proceeded.
Unfortunately i am running into another issue after that, where the
control-plane pods are not starting and the minishift deployment fails,
since the API access times out.
Would be inteeresting to see if you get the same once you deal with the SSH
stuff

How to Fix Install VMware Tools Grayed out Issues 2022

Leave a reply

1. Error Description:

The “Install VMware Tools” in VMware Workstation is grayed out and cannot be clicked to install.

How to install VMware tools if the option is grayed out in VMware Workstation - YouTube

 

2. Solution

Although VMware Tools is grayed out, there is a linux.iso in the VMware download package, which is what we need, as follows.
1. Mount the image file
Open VMware, click Virtual Machine>>Settings>>CD/DVD, then select “Use ISO image file” in the “Connection” on the right, then select the linux.iso file in the VMware directory, select it. After that, click OK.

2. Connect the CD-ROM file
After completing the previous step, open the virtual machine, there is a “CD/DVD” icon in the bottom right corner of the virtual machine, click on it and select “Connect”, you will see a CD file on the desktop after successful connection. The screenshot is as follows.

3. Decompress and install
Open the CD file, there is a file named VMwareTools…. .tar.gz, move this archive to the directory where you want to extract it (e.g. /home/Documents/VMTools), then click on the archive, right-click and select “extract here” to extract it to the current directory.

Open a terminal, go to the unpacked folder, then go to the vmware-tools-distrib directory and type sudo . /vmware-install.pl and enter, followed by yes and enter again.

4. Restart the virtual machine
After doing the above, you will need to reboot the virtual machine. Here you can test if the installation is successful by copying a file locally and pasting it in the virtual machine, if it is successful then VMware Tools is successfully installed.

Error: Node Sass does not yet support your current environment: Linux 64-bit with Unsupported runtim

Error: node sass does not yet support your current environment: Linux 64 bit with unsupported runtime (93)

It is taken for granted that the versions of node and node sass do not match.

It is useless to refer to various upgrades and demotions of the forum. mmp.

There’s really no way to install sass:

npm install sass

My project will automatically use sass. If you are worried or node sass is still working, you can also uninstall node sass:

npm uninstall node-sass

At this point, your project should run normally. Anyway, this is how I run packaging.

Solution to error [error] LD returned 1 exit status in C language

This error is sometimes reported when writing C/C + + experiments:

[Error] ld returned 1 exit status

This error is sometimes reported, that is, when running, it will jump to the warning place to report an error, but the warning will not report an error originally.

There are several reasons:

1. Other functions are defined in the main function

2. When there are many codes, the function name of a library function is wrong, such as scanf, printf and main

3. A custom function has only a function name and no function body, but is called

4. The function name of the custom function is inconsistent with the parameters in the function body below, resulting in the non existence of the called function

5. The last running program has not been closed
