I was following this thread:

> ok, this is getting confusing now. we said: but then you say So: what’s the difference between “which JSON”, a “specific version of JSON” and the “specific package called JSON”? I am asking because every now and then it’s very useful to be able to Pkg.pin(JSON,version) in case of a bug somewhere. Would I have to go and find a previous uuid of JSON to be able to do that with Pkg3? If I should just RTFM please tell me, I haven’t read anything except this thread. thanks!
But wanted to ask something very specific. Now that 1.0 is released, how can I pin a package to a specific, older version? Here’s a concrete example. On Julia v0.6.4, the following works:
```julia
Pkg.pin("Blink", v"0.6.2")
Pkg.pin("PlotlyJS", v"0.10.2")
```
How could one accomplish the same behavior on Julia v1.0.0 ?

Thats what the help says (on 0.7):
```julia
(v0.7) pkg> ?pin
pin pkg[=uuid] ...
Pin packages to given versions, or the current version if no version is
specified. A pinned package has its version fixed and will not be upgraded
or downgraded. A pinned package has the symbol ⚲ next to its version in the
status list.
(v0.7) pkg>
```
So if you have Blink v0.6.2 and PlotlyJS v0.10.2 installed,
```julia
pin Blink
pin PlotlyJS
```
should be sufficient.

That makes sense. How can I resolve the uuid of v"0.6.2" of Blink and v"0.10.2" of PlotlyJS?

If you just want to pin the current version the uuid is not required.

That makes sense as well. But what if I want to pint to a specific, older version of the code?

The uuid refers to the package, not the version. If you want to pin a specific version, use `add` to obtain it, then `pin` to pin it.

I tried this as I need package “GDAL” of version 0.1.2 pinned in Julia 0.7. But it does not work as expected.
(v0.7) pkg\> add GDAL@0.1.2
Resolving package versions…
Updating `~/.Julia/environments/v0.7/Project.toml [add2ef01] + GDAL v0.2.0 updating `~/.Julia/environments/v0.7/Manifest.toml`
strange behavior?

You are posting the same question in multiple places. There is no need for that.

oh. Thank you for letting me know. I will delete one if I get a solution.

No need to delete it now. The reason for this is to prevent people putting time into answering your question, when it might have already been answered elsewhere.
Short answer is you first have to add the package before pinning it, for full answer see: [How to pin a package to a certain version using Julia 0.7? - Stack Overflow](https://stackoverflow.com/a/54216576/2875964)

What wrong in Pkg.pin(“DataFrames”,v"0.17.1") ?

Either `pin DataFrames@0.17.1` in Pkg REPL mode or
```julia
using Pkg
Pkg.pin(PackageSpec(name="DataFrames", version="0.17.1"))
```
