I need to reinstall nodejs in windows 7 in a shorter character folder (closer to root, that is) than the one previously used since the character length is giving me problems with some packages.
However, when I reinstall, npm always installs in the PREVIOUS folder. How can I perform a new, fresh installation? Specifically, where I can select the folder where the packages will be installed?
Thanks.
I just found out about:
npm config set prefix C:\blahblahblah
Hope this solves my problem.

Internet research indicates that one can remove the Cygwin package files to save space. Within the Cygwin installation folder, I have a subfolder (say) http%3a%2f%2fcygwin.mirror.constant.com%2f reflecting the mirror site. The file http%3a%2f%2fcygwin.mirror.constant.com%2f/x86_64/setup.ini seems to contain all the information about installed packages. The only other folders/files are in the following two folder trees:
http%3a%2f%2fcygwin.mirror.constant.com%2f/noarch/release/*
http%3a%2f%2fcygwin.mirror.constant.com%2f/x86_64/release/*
Can I remove everything in the http%3a%2f%2fcygwin.mirror.constant.com%2f folder tree except http%3a%2f%2fcygwin.mirror.constant.com%2f/x86_64/setup.ini and still have the installer know what I have installed, what needs updating, and what needs downloading for a re-install?
The information about installed package is stored in
/etc/setup/installed.db
the cache in http%3a%2f%2fcygwin.mirror.constant.com%2f
is only needed during installation or re-installation of any package.
See info in the Cygwin User Guide
https://cygwin.com/cygwin-ug-net/setup-net.html#setup-localdir
After installing Cygwin, the cache is no longer necessary, but you may
want to retain the packages as backups, for installing Cygwin to
another system, or in case you need to reinstall a package.
I haven't been able to find any questions/answers regarding how to install two versions of Node.js (such as v10 and v14) on the same computer without using NVM. I can't use windows-nvm because it requires admin privileges, and I'm working on a company laptop as a standard user.
I need to be able to install multiple different versions of Node.js because different projects under the same company use different versions of Node.js as a necessity.
Is the only way to uninstall the installed version and install a new version every time? Is there any way I can have v10 under C:\Program Files\node10, and v14 under C:\Program Files\node14?
To be clear, the admins are willing to grant me specific privileges or install any software needed in order to get this working. We have tried using something called RunAsTool to try to let me run NVM as an admin, but this doesn't work because of its limitations.
Another option would be to grant me admin rights to any files and directories needed for NVM to function, but there is no list of those files/folders that I can find.
A third option would be to simply install two different versions, but when you install a new version, the previous version gets removed, even if it's installed under an unusual path like C:\Program Files\node16.
There's no easy way to do this, I think. Broadly you need two things to get node working on Windows: the nodejs folder with the executable in it, by default c:\Program Files\nodejs, and the path to that to be on the system path before any other node paths.
Unfortunately both writing to c:\Program Files and changing the system path require admin rights.
However, there is a somewhat clunky workaround. The overall idea is to put the nodejs folder somewhere where you have write access, point the system path at it, and it should run. Then you can switch versions without admin rights by replacing the folder. To do this:
With admin, install the first version you want to use. Copy the c:\Program Files\nodejs folder somewhere where it won't get deleted on a new install: say c:\nodejsbackups\v10\nodejs if it's version 10.
Install the second version you want to use, and copy the nodejs file to the same place, say c:\nodejsbackups\v14\nodejs.
Also copy it to a place you will run it from and where you have write access, say c:\nodejs if you have write access on the c: drive, or your user profile somewhere if not.
Still with admin rights, edit the system Path environment variable (NOT the user path). Find the entry to c:\Program Files\nodejs and remove it. Add an entry for c:\nodejs. Or just edit it.
I found that to get Visual Studio node apps to work I then had to also uninstall the original node using Control Panel/Programs and Features.
Now fire up a command prompt and do node --version and npm --version and you should see the second version is working.
To switch versions, without admin delete c:\nodejs and then copy the first version to there from c:\nodejsbackups\v10\nodejs. Restart your command prompt, issue the same commands, and you should see the first version is now working.
This seems to work on some very limited testing, but I think you need to test it all works for your use cases. There may be programs like Visual Studio that assume node is at c:\Program Files without using the path. In the end it may be better to beg for admin rights.
Install here:
Delete %NVM_HOME% and %NVM_SYMLINK%
Add path relative
Enjoy :)
I installed tcl to learn it, however, I installed all the files in the wrong location. I am trying to uninstall it, But the uninstall file does not work. I am trying to carry out the instructions form their website:
To uninstall ActiveTcl, run the "uninstall.tcl" script that is located in the directory where you extracted the ActiveTcl archive. Note that you must use the "wish" in the distribution you wish to uninstall. For example:
% /path/Tcl/bin/wish /path/Tcl/lib/ppm/log/ActiveTcl/uninstall_ActiveTcl.tcl
stored, by default, in the directory /lib/ppm/log/ActiveTcl. You must use the wish interpreter from the distribution you wish to uninstall. Ensure that you do not run the uninstall script from a directory that will be removed during the uninstallation.
For example:
% /path/Tcl/bin/wish /path/Tcl/lib/ppm/log/ActiveTcl/uninstall_ActiveTcl.tcl
Note: if you are uninstalling both ActiveTcl and Tcl Dev Kit, uninstall Tcl Dev Kit before uninstalling ActiveTcl.
There is no uninstall_ActiveTcl.tcl. I do see an "uninstall" file but it does not have an extension, and I do not know how to run it.
Any help is appreciated
Thank you
Try editing the file to a uninstall.tcl file and see if that works. Take a back-up first though. Because we might need that file later
I re-installed it in a new location, compared the files that were installed between the old and the new location and deleted the file sin the old location. Unfortunately I could not delete many of the hidden files, as I did not know if they were there originally or if they belonged to Tcl. I am really surprised and disappointed there is no easy way to uninstall tcl properly.
I strongly suspect that you should uninstall ActiveTcl as follows:
Open a command prompt
Change directory to where you found the install file - e.g.
$ cd path_to_Tcl_installation/bin
Run the file
$ ./uninstall
On linux systems, you don't need any particular file extension in order to be able to run a file.
I don't know CentOS but a little googling led me to a forum thread that describes how to open a command prompt.
Good luck
I have node and npm with existing packages currently installed to the C drive on Windows. My C drive is an SSD with a low amount of space. How can I move the node installation to a different drive? Would I need to reinstall node and all packages? The current node installer doesn't seem to specify drives.
You can move the node.exe to the d drive. Then check your environment path. Type set in a command window or in computer properties. Make sure you have the folder that contains node.exe in your path. Running node in a command window will work from any folder then.
For installed npm packages, ie.. node_modules folder.. That just needs to be in a directory above where your writing your code, so try putting that folder in d:\ Assuming your going to be writing your apps on the d drive now.
In .npmrc file, change prefix setting to desired folder. Global packages get installed in node_modules under that folder
I'm not sure what you are talking about, the node installer has this page.
What version of node are you trying to install? This screenshot is taken from v0.11.7 of node.
I know this post was basically forever ago, but I found a much easier way than manipulating the path. Simply uninstall NPM using the npm uninstaller, reinstall on your other drive with a new folder called nodejs. It'll create the folder in there appropriately and npm will be successfully installed on you D drive.
Search -> Environmental variables of system
click on path ( both )
click on new
add the path of your node.exe file
boom you are done*
node -v to check
I´m doin a unattended cygwin installation and I was wondering if there will occure any problems without a setup.ini.
Following: my "install-folder" includes a setup.exe and a subfolder release (within all the packages packed).
I´m starting the setup silent (with Nsis) and install the packages. In NSIS I define the Root, the location of the packages etc.
I think it works so far (I´m not sure because i´ve got a curious error in cmake). There are many instructions how to modify the whole setup for an offline installation. But I don´t get the point why I have to modify it at all.
I hope anyone has got experience with this issue!
#Daniel Le cygwin installs the packages without the .ini (all of them). And there has nothing to be downloaded because the packages are on the local machine.
I believe the setup.ini is essential to the setup process, as it indicates which packages to be downloaded and installed.
The Ini file is so far only a description for file locations and paths to be set as default. It is not necessary to have the ini file if you wanna install some packages!
That´s my conclusion.
